From the conveyor of the Togliatti plant, AvtoVAZ moves several options for Samara cars with VAZ-2111 engines. These engines are equipped with a multipoint distributed fuel injection system, which has several versions.
The first version of the system is the fruit of the joint work of AvtoVAZ and the American firm General Motors (GM), which is intended only for export. The car corresponds to the ecological standards of Euro-2, a neutralizer is installed on it, in the injection system there is a oxygen concentration sensor (DCC) installed in the flow of exhaust exhaust gases (VOG). But the engine should work only on unleaded gasoline, otherwise the named elements will fail. Accessories to such an injection system are supplied by GM.
The second option is intended for domestic market. His feature - the electronic unit Management (ECU) own development January-4, the components of the Russian system, there is no neutralizer and DCC in it, the use of eatelled gasoline is allowed. Details of the second variant of the system are produced by small parties at different domestic enterprises. Contact connectors of nodes and blocks in the systems of the first and second options are the same, some of them are interchangeable.
The third option has appeared thanks to cooperation with the German company Bosch. Engine 2111 added five "forces" - now it develops 57 kW (77 liters.) Power. A new intake manifold has been installed, and camshaft with more "wide" phases. Two control units were developed: a cheaper ECU-M1.5.4, which provides Euro-2 toxicity norms, and promising EBU-MR 7.0, which is more expensive, but it meets the stringent requirements of Euro-3. In the third version of the system, the contact connectors are original, and the system is not compatible with two first.
To determine what type of injection system is equipped with an engine of a particular car, it is possible for an inscription on the ECU, which contains the VAZ catalog number, name, serial number and the date of the block. ECU is also called the controller. Data for different types Controllers are shown in Table. 1-3.
ESAU-D controllers are running the program laid into the ECU storage device. Different versions of programs allow you to create modifications of controllers to work with different models Engines and ensure the implementation of various environmental norms.
Data on versions software (PO) for ESAU-VAZ, its correspondences, the type of controller and their interchangeability are shown in Table. 4. The table of interchangeable blocks and programs is combined into groups.
Decryption of the designation for the development of VAZ
As an example, consider the designation: M1 V 13 O 54.First discharge
- Letter and figure (in example - M1) - denotes the type (family) of the controller:J4 - the family of control blocks January-4;
J5 - Family of control blocks January-5;
M1 - Bosch Control Blocks Family M1.5.4;
M7 - Bosch Control Blocks Family MR7.0 Motion.
Second discharge

16 - Euro-3 toxicity norms (EOBD), engine 2111.
Fourth discharge
- Letter (in the example - o) - denotes the level of software (a ... z); The further letter from the beginning of the alphabet, the older the level of the software.Fifth discharge
- Two digits (in example - 54) - denotes the calibration version (00 ... 99); The greater the number, the newer calibration.Thus, the example above is deciphered as:

V - family front-wheel drive VAZ;
13 - 8 valve 1.5 liters engine 2111, the norms of toxicity of Russia;
O - version of the software;
54 - Calibration version number 54.
Changing calibrations can be achieved some improvement in the dynamic characteristics of the engine, reducing fuel consumption and toxic emissions to VOG. To change calibrations there are special programs and devices for their implementation, and for different types Controllers have developed different methods for replacing the "chip tuning" (adjustments of the ECU control program). As an example in Table. 5 shows tuning firmware for ECU BOSCH M1.5.4 1411020-70.
Component composition, functions, location of ESAU-D elements on the example of the VAZ-2111 engine with the MP7.0 Bosch controller
ESAU-D, equipped with an MP7.0 controller and installed on the VAZ-2111 engine, on the principle of action and the device is similar to the Motronic Bosch system and refers to ESAU-D with the combination of injection and ignition functions.In addition to controlling injection and ignition, ESAU-D manages turns idle move, electric displacement, blowing the adsorber of the gasoline vapor capture system, control lamp " Check Engine", Cooling system fan and air conditioner compressor coupling (if installed). In addition, ESAU-D generates signals, proportional vehicle speeds and fuel consumption for a route computer, as well as a signal about the rotational speed of the engine crankshaft for a tachometer. The controller provides interaction with an external diagnostic device through a special connector located in the car. Domestic ESAU-D has a self-diagnostic function that allows you to fix the faults that cause them to identify them, write to the memory, inform the driver with the inclusion of the Check Engine control lamp. Diagnostic information can be removed from the EU RAM through the diagnostic connector to the external scanner.
It should be noted that the inclusion of the "Check Engine" lamp during movement does not require an instantaneous engine stop, as, for example, in situations with emergency disappearance of oil pressure in the lubricant system or emergency engine overheating, but only indicates the need to check the engine in the near future. The ESAU-D controller has emergency modes that provide engine operation when many malfunctions occur, with the exception of the most difficult, for example, when the crankshaft position sensor fails. To ESAU-D, you can connect the car protection system from the hijacking.
Constructive ESAU-D consists of a set of sensors, computer, a set of executive devices and wiring harness with connectors.
Electronic control unit (controller)
ECU is a central device ESAU-D. It receives analog information from the sensors, processes it with analog-to-digital converters and the program embodied in the ROM implements the control of actuating devices. Communication ECU C. electrical scheme Exercised through a 55-pin plug connector. ECU is placed under the appliance panel console (see Fig. 1).
Purpose of contacts and some data for control are shown in Table. 6.
ESAU-D Sensors (VAZ)
Air Flow Sensor (DMRV)
The DMRV GM and Bosch used in VAZ ESUs differ in the form of the housings and output signals. The GM sensor (HFM-5) generates a frequency signal for GM and January-4 controllers, and the Bosch sensor (HFM-5SL) - Analog signal for Bosch and January-5 control units.
Characteristic malfunction DMRV - Cutting wires from the sensor or breaking the platinum thread of the sensor itself. With such malfunctions, idling turns rise to 2000 rpm. During the movement in separate modes, detonation is possible.
When the sensor fails, it may occasionally produce an incorrect signal (typical for frequency sensors), and this does not lead to a malfunction code in the controller's memory. In this case, even when moving without acceleration, large "failures" arise and idle becomes unstable, which can lead to engine stop. ESAU-D In the case of DMRV failure, it turns back to the backup mode, calculating the air flow rate from the sensor of the Crankshaft position of the DPKV, (the signal contains information about the engine speed) and by signal with DPDZ. The fault is recorded in the memory of the error (P010-P0103) corresponding to the home and is indicated by the Check Engine lamp.
Throttle position sensor (DPDZ)
The sensor is designed to determine the position. throttle valve.
When the flap is closed, the signal issued by the sensor is 0.5 ... 0.6 V, with an open position - 4.5 ... 4.8 V.
The data on the position of the throttle is necessary for the control unit for calculating the duration of the electrical impulses of the nozzles control and determining the optimal angle of the ignition advance.
Potentiometric DPDS injector engines VAZ usually fail due to wear of the conductive paths of the resistive plate and incorrectly selected spring force, pressing the resistive plate to the connector contacts.
Brand sensors often come across russian productionThey give out an unstable signal with a voltage of 0.25 ... 0.7 V with a closed throttle.
The sign of a faulty sensor is elevated or floating idle speeds. At the failure of the DPDS ESAU-D, it replaces it with a signal calculated in the rotational speed of the crankshaft and the DMRV signal. The fault is recorded in the memory with the corresponding error code (P0122-P0123) and the "Check Engine" lamp is indicated.
Coolant temperature sensor (DPU)
The temperature sensor is a thermistor with a negative resistance coefficient (R \u003d 470 OM at 130 ° C and R\u003e 100 com at -40 ° C). The ESAU-D controller on the drainage of the DRP voltage calculates the temperature of the coolant using its value in most engine control functions. At the failure of DRP, ESAU-D calculates the temperature of the engine operation and the testimony of DMRV. The malfunction of the DTP is recorded in the memory of the error code (P0115, P0117, P0118) and is indicated by the Check Engine lamp. In tab. 7 shows the data for checking the temperature sensor using a digital tester.
Detonation sensor (DD)
A sensitive piezoceramic element is used in DD, which generates alternating voltage during vibration. The amplitude and frequency of the signal depends on the level of detonation in the engine, which allows the ESAU-D controller to adjust the ignition advance angle to clean the detonation. You can check DD using an oscilloscope: A properly working DD generates a signal of a sinusoidal shape with a duration of 4 ... 6 ms and an amplitude of 2.5 ... 3 V (causing detonation with a sharp discovery of the choke on the operating engine). The malfunction in the DD path is recorded in memory with the appropriate error code (P0327, P0328) and is indicated by the Check Engine lamp.
Oxygen concentration sensor
Modern injection systems are performed in two versions - with feedback And without it. Feedback implies the presence of DCC (lambda probe) in the receiving pipe and the catalytic neutralizer of exhaust gases. With the ratio of air and fuel in the fuel-air (TV) mixture 14.7: 1 (this ratio is called a stoichiometric) catalytic converter the most effectively reduces the amount harmful substances (CO, CH, NOX) emitted with exhaust gases. To optimize the composition of the exhaust gases, in order to increase the fuel economy and the achievement of the greatest efficiency of the neutralizer, the fuel supply control is applied closed contour With feedback using a signal to DKK. The oxygen concentration sensor, the sensitive element of which is in the stream of exhaust gases, generates a signal as a buckling voltage change from 0.1 to 0.9 V (value 0.1 V - a poor TV mixture; 0.9 V is a rich TV mixture), With the transition through the average value of 0.45 V, when the TV mixture is stoichiometric. The ESAU-D controller based on the data obtained from the DCC changes the composition of the fuel-air mixture, maintaining it close to the stoichiometric.Operate and heated to operating temperature (more than 300 ° C) DCC generates a frequency signal with a frequency of 1 ... 5 Hz. The malfunction in the DCC tract or the failure of the sensor itself is recorded in the memory of the corresponding error code (P0130, P0132, P0134) and the "Check Engine" lamp is indicated.
Car speed sensor (DSA)
DSA consists of a stator with a lounge element and a rotor with a magnet. During the movement of the car, DSA produces a signal with a frequency of 6 pulses per 1 m movement. The ESAU-D controller determines the speed at the frequency of the DSA pulses. The characteristic malfunction of DSA is a mechanical damage to the sensor, the speedometer does not work and the Check Engine lamp lights up. One of the codes is entered into memory - P0500 or P0503. It should be noted that at the engine work this refusal is not reflected in any way, which is sometimes used by unscrupulous owners, turning off DSA to hide real mileage car. On the example of the operation of the car VAZ-21102, the average duration of the DSA failure domestic production does not exceed 1.5 ... 2 years (or 20 ... 30 thousand km run).Crankshaft position sensor (DPKV)
On VAZ-2110, 2112 cars with a distributed injection of gasoline, DPKV is controlled from a special disk (sensor rotor) with 60 teeth, which are placed in a pitch of 6 degrees. For synchronization, two teeth are absent. The beginning of the synchronization reference for the ESAU-D controller is the first tooth after two missed, the crankshaft is at the position of 114 degrees to the top dead point (NTT) of the 1st and 4th cylinders. The toothed disk is located on the pulley crankshaft To drive the generator, and DPKV - on the oil pump lid. In the gap between the sensor core and the disk tooth 1 ± 0.4 mm and the frequency of 30 ± 5 rpm, the minimum amplitude of the AC voltage at the DPKV output must be at least 0.28 V. Resistance to the serviceable sensor is 500 ... 700 ohms. There are cases of contact loss in the connector and cliff of supply wires. The supply wires to protect against interference are shielded, the screen breaking can also lead to failures in the DPKV path.The malfunction in the DPKV path or the refusal of the DPKV itself is recorded in memory with the appropriate error code (P0335, P0336) and the "Check Engine" lamp is indicated, the engine will not work.
Executive elements ESAU-D (VAZ)
ElectricalSonasos (EBN)
In ESAU-D (VAZ), an ebne of a turbine type is used (Fig. 9, 11).
Ebn turns on the controller through the relay. It is also possible to enable EBN through the diagnostic connector (closed the contact between themselves. G and H). The ESAU-D program provides an automatic shutdown of EBN, if after 2 s after switching on the ignition or starter, the engine crankshaft does not rotate. On the Samara cars, different instrument panels are mounted with different fuel level pointers. In this regard, the fuel level sensors (located on the Benzonasos monoblock) also exist in two versions:
21083 (with a high instrument panel), the resistance of the sensor 0.25 ohms - with an empty tank and 20 com - with full;
2112 (for cars with Torpeda 2108, 2110 and 2115). Ebn assembled with a high-panel VAZ car sensor have a yellow setting mark in the arrow zone (when installing the EBN arrow should look back) and for low - without a label or with a black mark. Ebn itself is the same and if they accidentally confuse, then there will be incorrect fuel level readings, but the engine will work normally.
Fuel injectors
Fuel nozzles (see Fig. 10, 11) are electromagnetic devices and serve for gasoline injection on inlet valves Calculated ECD of the amount of fuel. The MP7.0 Bosch controller uses the injectors driver with a self-diagnosis function. It determines the failure of a break, a short circuit for a mass or defects of the power control circuits of the nozzles. At the same time, the error codes P0201, P0202, P0203, P0204 and the CHECK Engine lamp turns on. The malfunction of this character is easily diagnosed with a multimeter by checking the resistance of the winding of each nozzle (11 ... 15 ohms), the connective harness is less than 1 ohms.Injectors different manufacturers (Bosch, GM or domestic) interchangeable by internal resistance and landing places. The nozzles are better to change the set, as their fuel sprayers are different. Injectors russian manufacturers And Bosch is less susceptible to corrosion and, accordingly, serve longer. On the saddles of the injectors and at the ends of the locking elements, solid resinous sediments appear over time, the main reason for the failure of the injectors. As a result, the following symptoms appear: embarrassed, unstable idling, dips during acceleration, increased flow Fuel, power loss and turret engine. Therefore, especially for engines with a mileage of more than 100 thousand km, it is recommended to clean the nozzles. Specialists of the company "Inomor" held comparative analysis The effectiveness of various solvents and devices for cleaning the nozzles and came to the conclusion: all devices are close in design, their capabilities and differ only at the price. But the cleaning solvents are different efficiency. The best was the solventccentrate of the American company "Carleb Wedge" (Carbol Clean). According to reviews of firms from Angarsk, Krasnodar, Moscow, Novosibirsk, Togliatti, this concentrate is significantly (on average 15 ... 20%) more efficiently. Accordingly, the flow rate is less and cleaning is faster.
Ignition module (MZ) with candles
In the ESAU-D (VAZ) ignition system, a MH is used consisting of a 2-channel electronic switch and a pair of two-water ignition coils (see "Repair & Service" No. 6, 2003, Fig. 11 on p. 62). The ignition system ensures detonation deviations on a special algorithm using DD. The ignition system has no moving parts and therefore does not require maintenance. In the event of a malfunction of any element of the MH, it is necessary to replace the entire node assembly. Signs of malfunction MH are diverse: from engine interruptions in separate modes before stopping it. The control lamp does not light up. To diagnose malfunction in the ignition system, it is necessary to check the presence of the MH power (contact. D "- power +12 V, contact." C "- common), the presence and serviceability of the connection of the controller with the MH (Cont." B "MH - Cont. 1 Controller and contact. "A" of the Ministry of Health - Cont. 21 of the controller) and the resistance of high-voltage wires (approximately 15,000 ohms).Domestic MC 42.3705 consists of two ignition coils with two high-voltage conclusions and a 2-channel switch collected in one monoblock and compounds are filled (Fig. 12).
Until April 1999, the modules were poured by a silicone compound, which adopted badly to the details and was not plastic enough. Heating, silicone peelled from the body of the monoblock and moisture fell into the resulting cracks, after which the module was out of order.
From April 1999, polyurethane is used instead of silicone compound. After that, the number of failures of the MH decreased by 80%. The MH, manufactured by the Moscow Plant MZATE-2 (previously ATE-2), is used with Bosch and January-5 controllers. To control systems with GM and January-4 blocks, this module is not suitable.
The VAZ-2111 engine ignition system is equipped with A-17 DVRM (or analog) with an interference resistor with an interference resistance of 4 ... 10 com and copper core. The gap between the electrodes is 1.00 ... 1,13 mm. The VAZ-2112 engine is equipped with AU-17 DVRM candles that can be used on the VAZ-2111 engine. Based on the experience of the operation of VAZ-21102 cars, the average duration of the work on the refusal of candles of domestic production is 1-1.5 years (or 20-30 thousand km of mileage).
Idling regulator (RXX)
RXH (Fig. 13) is installed in the bypass (bypass) channel of air of the throttle nozzle and adjusts the rotational speed of the crankshaft at idle when the throttle valve is closed (see the scheme in Fig. 11), while it helps to reduce toxicity exhaust gases. When braking the engine, when the choke is sharply closed, the RHX increases the amount of air supplied to the throttle bypass, thereby ensuring the depletion of the TV mixture. It also provides a decrease in exhaust toxicity.It should be noted that the improper operation of the engine at idle is not always associated with the refusal of the RCX. Disturbance of the idling engine can be caused:
receded TV mixture;
re-entered TV mixture;
defect throttle;
Incorrect operation of the ventilation system carter gases;
Brown air filter;
Air seats in the intake manifold.
Only after the elimination of all these problems should be dealt with RXX. Verification of RXX in the absence of a special tester is very problematic. The only thing that can be done is to ring the windings of the RXX in the absence of a cliff and short circuit (the resistance of the windings should be 40 ... 80 ohms) and inspect it for obvious defects. Based on the experience of the operation of VAZ-21102 cars, the average duration of developments on the refusal of the PCX domestic production (2112-1148300-82) is 1.5-2 years (or 40 ... 50 thousand km mileage). RCX failure identified by the diagnostic system is fixed by error codes P0506, P0507 and the inclusion of the "Check Engine" lamp.
Diagnostics ESAU-D (VAZ)
Self-diagnostic function
ESAU-D (VAZ), as well as the "Motronic" system, has a built-in self-diagnostic function, by which the signals generated by sensors and signals entering the actuators, with the regular values \u200b\u200bof these signals, which are stored in the constant memory of the ECU in the ECU . Detected faults and the corresponding mode parameters are entered into the controller's memory. These data can be analyzed during maintenance via diagnostic equipmentconnected to the standard diagnostic connector.For prompt informing the driver about the work available ESAU-D ErrorIn combination of VAZ devices there is a check engine test lamp. If this error occurs in the system for a short time, and then it does not appear for a long time, then after some time the lamp goes out (however, the diagnostic fault code is stored in memory). If the error does not disappear, the lamp burns stand alone, recalling the need for diagnostics. Clearing memory from recorded error codes is made either by disconnecting the controller from the power supply for a while at least 10 seconds or using special diagnostic equipment.
Diagnostic code (DC) malfunction, codes table
AvtoVAZ seeks to maintain the compatibility of fault codes with the ODB-II standard (SAE / MFG). Although not all codes are supported, gradually their number is growing.ODB-II error code format Next:
The first letter in the code means a car system in which a malfunction arose: B - Body (body), C - Chassis (chassis), P - PowerTrain (power unit), U - Network (on-board network).
The first digit in the code means the authorship of the error: if "0", then this is SAE (J2012); If "1", then this is MFG (specific code that is necessary for the car manufacturer).
The second digit in the code means the subsystem and decrypts as:
1 - Fuel and Air Metering Fuel and Air
2 - fuel-friendly engine subsystem (injection circuit) Fuel and Air Metering (Injector Circuit);
3 - Ignition Systems or Misfire (Ignition Systems or Misfire);
4 - Auxiliary emission management subsystem (Auxiliary Emission Controls). It should appear in the ECU VAZ with the transition to the ejection norms of Euro-3;
5 - Engine, speed and idle speed control subsystem (Vehicle Speed \u200b\u200bControl and Idle Control System);
6 - Computer output chains (Computer Output Circuit);
7 - Transmission (TRANSMISSION).
The last two digits mean the actual fault code itself.
In tab. 8 are given diagnostic codes Faults that are supported in controllers
AvtoVAZ (fatsed codes used by the Bosch MP7.0 controller).
Methods and practical receptions of reading diagnostic codes (DK)
Reading DC with the "Check Engine" lamp
This method is applicable to GM and January-4 controllers. Bosch controllers can only be interviewed using diagnostic equipment.In order to count the fault codes using a control lamp, you need to close the contacts A and in the diagnostic connector (see Fig. 11) and turn on the ignition, without a winding engine. At this moment, the Check Engine lamp should give code 12 three times in a row. The code indication sequence is as follows: Turning on the lamp, short pause, two inclusions in a row, a long pause and so twice. Code 12 is not a malfunction code, it suggests that the self-diagnosis system is operational. If the code 12 is missing, the self-diagnosis system is faulty.
After issuing the code 12, the Check Engine lamp will begin to produce previously detected and recorded fault codes in the order of increasing their number. Each code is issued three times. And so in a circle. If malfunctions are not detected, only code 12 will be issued.
Reading DC with special diagnostic equipment
1. DST-2 tester or similar overseas production tester.The Scanner Tester of the Samara NPP "New Technological Systems" DST-2 and its modifications that appeared in 1995 provide ample opportunities for the diagnosis of ESAU-D (VAZ). In addition to controlling the current ESAU-D parameters, sensor checks and executive mechanisms DST Family Scanner Testers allow you to control and register the ESAU-D state in the dynamics, which helps in finding non-permanent faults. The only drawback of the DST family testers is a high cost.
2. Route computer (MK) with diagnostic function.
There are many MK options, but only on-board computers of the Kursk OJSC "Rovmmash" have a certificate of auto-vase and are supplied to the conveyor for car configuration "Suite". This is AMK-211000 for cars of the tenth series and AMK-211500 - for installation on all VAZ small cargo cars. The available MK in their capabilities are little inferior to the testers scanner, for example, DST-4M, but the cost of these devices is even higher.
3. Personal computer with special (software and hardware) connected interface.
This method of reading codes and at the cost of implementation and according to the diagnostic possibilities provided is the most applicable in the "home" conditions. Indeed, the diagnostic program distributed on the Internet (the author used "Mytstr R12") and adapters (see http://www.autoelectric.ru/) provide ample opportunities for the diagnosis of ESAU-D (VAZ). The main advantage of the computer in front of the tester is the convenience of saving test results. In order to save the results, it is enough to click on the "Record" button, set the file name and add a comment if necessary. In the future, it is enough to compare the obtained parameters with regular parameters Good ESAU-D and make the necessary conclusions.
Upon completion of the repair and to control the re-appearance of the DC, it is necessary to clear the memory of the controller. There are two ways to erase from the memory of the fault codes. Codes can be erased using diagnostic equipment, as well as if disable control unit from rechargeable battery for 30 s.
General approach to the search and troubleshooting in ESAU-D
Condition normal work All ESAU-D components are the working condition of all mechanical, pneumatic and hydraulic Systems Engine. Therefore, before the start of the diagnosis of ESAU-D, you must check:The working condition of the cylinder-piston group (the compression measured on the heated engine in all cylinders should be at least 10 kg / cm2);
tightness of intake and exhaust manifolds;
correctness of the installation of the phases of gas distribution;
Fuel system service (Normal pressure in fuel system should be 2.5 ... 3.5 bar);
state of power supply (voltage in on-board network On the running engine, 13.2 ... 14.7 V and when starting it should not fall below 8 V).
ESAU-D has a number of operating parameters, compliance with the regulatory value of which determines the performance of the system as a whole. Their check is carried out using an oscilloscope, a digital multimeter and strobe. Note that the check of some of the parameters is possible only on the engine running. Therefore, at the first stage of diagnostics, you need to start the engine and correctly estimate the state of all ESAU-D components.
An ideal prerequisite for the correct diagnostics of ESAU-D is the appearance of a diagnostic malfunction code. Although not always, the DC accurately indicates the root cause of malfunction. More often, DC indicates a consequence of what happened. And only a detailed analysis, checking the doubt of ESAU-D parameters help to find a malfunction.
A large number of electronic devices in modern car requires the owner of special knowledge and techniques in operation and maintenance. The following features of the operation of the vehicle with ESAU-D must be known to maintain and repair their car.
1. It is possible to de-energetize the ECU not earlier than 30 seconds after turning off the engine, otherwise information will be erased from RAM. In order to restore lost information, you need to start the engine and give it to warm up to the operating temperature. After starting the engine, the check engine check lamp will be lit for some time, which is not a malfunction.
2. On all injector engines VAZ after an unsuccessful start attempt (more often it happens at air temperature below -25 ° C), "flooded" candles can be dried by turning on the purge mode. To do this, it is necessary to smoothly click on the gas pedal and on 5 ... 10 with the starter. For ECU, such actions will be a signal to turn off the fuel supply.
3. All controllers are designed in such a way that at ambient temperature to + 25 ° C, they retain performance at a supply voltage of 18 V in two hours. At voltage 24 V, they are guaranteed to retain their performance for at least five minutes. Cases of failure of controllers due to increased voltage in the onboard network, even if the voltage regulator fails, is not recorded.
4. Car controllers "Tenate" series are compatible with onboard computer 2111-3857010 (16.3857). The control units that are installed on the Samara-2 car are compatible with onboard computer 2114-3857010 (15.3857).
5. In order to block the start of the engine when installing the security alarm on the injection engines of the VAZ car with controllers of the M1.5.4 or "January 5.1" (inapplicability to MR7.0, the *) is noted to "break" any of the following wires:
control of the ignition module;
gas station management;
Control Injectors; *
The wire connecting the 15th terminal of the controller (Ignition signal on the engine control system) with a 18-terminal block;
"Plus" or "mass" wire of the fuel pump relay; *
To climb among themselves or clogging on the "mass" of the wire of the inductive sensor. In addition, it is possible to climb through a resistor with a par value of 680 Ohm - 1 kΩ wires (signal and power) sensor of the throttle position sensor. *
When breaking conductors that feed the ignition module or nozzle, it is necessary to use openingors, withstanding current of at least 3 A, and the wires of the supply chain of the fuel pump - at least 10 A.
Troubleshooting on the example of the VAZ-2111 engine with Bosch MP7.0 H controller
Previously need to check the operating parameters of ESAU-D, which can be measured on disabled Engine (See Table 8).To start the engine you need:
The presence of fuel in the tank and normally working fuel pump;
good ignition;
so that the DPKV is;
In order for the nozzles (the failure of all the nozzles is unlikely);
In order for the controller (although its breakdown, even for domestic cars, is unlikely).
Electrical junction (EBN) is checked by characteristic sound. Also, when the ECU is turned on, gasoline pressure should appear in the fuel line (2.5 ... 3 bar). After turning off the pump, the pressure in the system should not fall quickly. If it falls, then most likely the fuel pressure regulator valve is faulty. For a short time it can be drowning, without completely shifting the tube (for example, a suitable clamp) reverse benzorota, creating the necessary pressure in the system. If EBN is "silent", the presence of +12 V on the pump block and then on the chain (see Fig. 11).
Ignition can only be checked with a reliable connection of candles with a mass, otherwise the control unit is easily increasing. To diagnose a malfunction in the ignition system, it is necessary to check the presence of the MH power (contact D +12 V, contact. C - general, see Fig. 11), the presence and serviceability of the connection of the controller with the MH (line B - Cont. 1 ECU and A - Cont. 21 ECU), check the resistance of high-voltage wires (about 15 com).
Initially, it is necessary to inspect the DPKV for damage to the wire and the screen. DPKV is the only knot in ESAU-D, without which the engine will not work. Resistance to a good sensor - 500-700 Ohm. AC amplitude measured on DPKV (Control. 48, 49 ECU, see Fig. 11) When scrolling the engine, the starter is 1 ... 2 V. There are cases of contact loss in the connector and breaking the supply wires. The supply wires to protect against interference are shielded, the screen breaking can also lead to malfunctions in the work of the Ministry of Health. The design of the crankshaft pulley has a rubber damper, due to poor vulcanization, the rubber is sometimes peeling from one of the pulley disks, and they are shifted. As a result, the impulses on the nozzles and the ignition come not in time. The engine in this case will also not work.
The electrical resistance of the nozzles is checked by an ometer. It must be 12 ... 15 ohms in each nozzle. The resistance of the wires in the connecting harness is less than 1 ohms.
The controller (ECU) is checked for power on a shut off and non-disconnected inputs (contact 18 and 37, see Fig. 11). In the absence of power, the main relay is checked, fusible insert and fuses X, Y and Z.
If the engine is poorly started in the cold time (at ambient temperature of less -20 ° C), you can scroll through the engine with a pressed gas pedal (in this case, the fuel will not be supplied) that will allow to blow cylinders. By letting the pedal, you can repeat the attempt to start. If it succeeded, it is either faulty PCH, or one of the sensors (most likely DPT). But the cause of poor start can be the low fuel pressure, due to the fault of the fuel pump or the fuel pressure regulator valve.
Also prevent the launch of the throttle position sensor (DPDZ). If the voltage on it is about 3.4 V, then it will not be possible to start. It can be turned off or stunned by providing voltage on it 0.1 ... 0.2 V.
In some cases, an emergency version of the engine starts, when all sensors are turned off from the computer, except for DPKV, and the attempt to start will be repeated. In this case, the engine may start, if experimental by determining the initial position of the gas pedal.
If he started, then it is necessary to check the ESAU-D parameters and its elements (see Table 9).
Using diagnostic codes (DC) when searching and troubleshooting ESAU-D
After starting and warming up the engine in any available methods Check diagnostic fault codes, pre-checking the performance of the diagnostic chain. How this fall is described in the instruction manual for a specific tester. If it is a tester scanner or IBM PC-software tester, then it is possible to check the entire ESAU-D periphery (executive mechanisms and sensors) and carrying out various dynamic tests. The resulting DCs must be analyzed to establish the causal relationship of what is happening in ESAU-D.The following conditions must be performed before checking:
The engine is heated to the operating temperature;
The engine runs on low idling;
Diagnostic contact is not closed for mass;
The DST-2 device (or similar) is not connected;
air conditioner (if any) is disabled;
The negative clip of the digital voltmeter is securely attached to the mass.
In tab. 10 shows diagnostic codes, possible faulty electrical chains, as well as additional manifestations of identified faults.
In the "Voltage" columns and "possible signs of chain malfunction" of this table, the following notation was adopted:
(1) - below 0.1 V for the first two seconds after turning on the slide without scrolling the engine;
(2) - below 1 in or above 10 V, depending on the position of the leading wheels standing car. When moving, the voltage varies depending on the speed;
(3) - varies depending on temperature;
(4) - varies depending on the level of vibration of that part of the engine on which the detonation sensor is installed (DD);
(5) - varies depending on the frequency of rotation of the engine;
(6) - voltage on the battery battery (B +) when driving the engine;
(7) - cliff;
(8) - breakage / circuit circuit;
(9) - the chain is closed for mass;
(10) - the chain is closed at +12 V;
(11) - varies in the range from the battery voltage to voltage less than 1 V in information from the duty of pulses;
(12) - with a relay on less than 0.1 V, and with a relay disconnected - equal to the battery voltage;
(13) - with the included control lamp The voltage is less than 0.5 V, when the battery is turned off on the contact, the battery voltage appears;
(14) - decreases with increasing duration and frequency of injection pulses;
(B +) - should be equal to the battery voltage.
The color of the wire (2nd column), indicated by P (purple), corresponds to the designation of the Kyrgyz Republic (red).
The concept of the hidden faults of ESAU-D
Some ESAU-D faults may have an implicit or hidden character. This may be due, for example, with a short-term change in the characteristics of ESAU-D components, which lead to errors in the system. Some motor testers have a special mode that allows you to record changes in ESAU-D parameters for a certain time to clarify the source of floating malfunction. In DST-2, for example, this mode is called "data collection".In tab. 11 shows the ESAU-D (VAZ) parameters with the BOSCH MP7.0 controller (removed using DST-2), which can be used to diagnose in the absence of malfunction of DC.

Following foreign car manufacturers Concern AvtoVAZ introduces hi-tech in your vehicles. One such example is an on-board computer, designed to identify a malfunction in the machine using a digital code. We invite you to find out how diagnosed on VAZ 2115 - error codes will also be decrypted in this article.
[Hide]
Diagnostics cars
Of course, to detect a malfunction in the work of the vehicle is impossible without diagnostics. It can be carried out through special equipment, which can be found on each specialized service station. But also to test your car for faults on your own. Note, when self-checking auto, error codes will not be as if diagnosed on equipment.
So, how to independently do the diagnosis, such a question came to each owner of these machine models. Now we will tell you more detail about it. But to diagnose the machine is half of the case, because the troubled fault combinations must also be decrypted.
- Find the Odometer button on the instrument panel. You need to hold it.
- Then check the key in the ignition lock to position 1.
- Having done this, the odometer button will need to be released.
- When you released the button, the arrows will jump on the instrument panel.
- Once again clam and release the odometer button. On the speedometer, figures will appear, denoting the version of the firmware on-board computer.
- Finally, for the third time, clamp and release the button of the odometer and you can see a fault combination. When independent check Error codes will be presented in a two-digit form, in contrast to the diagnostics on the equipment, where the faults are presented in a four-digit form.
Deciphering codes
As mentioned above, without deciphering the error codes, the diagnosis of the vehicle is meaningless. Therefore, the decoding of combinations should also be paid attention to. Especially if you do not want to pay for this considerable money to specialists for a hundred. So, let's start with combinations that appear during self-diagnostics of the machine.
Self-diagnostic codes
| Combination | Deciphering breakdown |
| 1 | Code 1 Indicates a malfunction in the operation of the microprocessor. Sometimes an error is corrected by flashing the device. |
| 2 | On-board computer reports the incorrect operation of the gasoline level sensor in fuel tank. There are problems with electrical wiring. |
| 4,8 | Too high or excessively low voltage in the vehicle network. |
| 12 | The incorrect operation of the diagnostic chain of the control lamp. |
| 13 | On the on-board computer stopped the signal from the oxygen level control device. |
| 14,15 | The control unit enters an incorrect signal from the antifreeze temperature sensor in the cooling system. In particular, the signal may be too low or overestimated. |
| 16,17 | The combination data when checking the car for error detection means the wrong on-board network voltage. It is necessary to carefully check the network for closures and cliffs, since the voltage rate is too high or very low. |
| 19 | On the on-board computer, the VAZ 2115 enters the incorrect signal from the crankshaft position control device. Check the chain. |
| 21,22 | The VAZ 2115 control unit comes to a very low or high signal from the throttle position control device. To eliminate a malfunction, it is necessary to check the performance of the device directly, as well as moderate the wiring. |
| 23,25 | A device for controlling the temperature of the suction air. The incorrect signal comes to the control unit from this sensor. Check the chain, as well as the sensor directly. |
| 24 | On the on-board computer, the signal from the VAZ 2115 vehicle speed sensor has ceased. |
| 27,28 | Error combinations data indicate an incorrect signal from the CO sensor on the auto control unit. It is recommended to check the circuit for cliffs and closures or replace the sensor. |
| 33,34 | Control device mass flow air. Error data indicate an incorrect signal from the sensor, as a result of which it should be replaced. There is also a chance of breaking in the chain, therefore it makes sense to check and wiring. |
| 35 | A malfunction is detected in the operation of the idle regulator. You should replace the sensor to restore the correct operation of the device. |
| 41 | An incorrect signal from the phase sensor enters the control unit. |
| 42 | This combination indicates a malfunction in the control wiring electronic ignition. Apparently, the ignition is all right, but the chain is diagnosed. |
| 43 | The control unit caught an incorrect signal from the detonation sensor. You should check the device or to diagnose the chain for cliffs. |
| 44,45 | In the injection system, the on-board computer recorded the depleted or enriched combustion mixture. In this case:
|
| 51,52 | The troubleshooting data indicate errors identified in PPZ or RAM devices. |
| 53 | On the VAZ 2115 control unit, the signal from the CO-sensor has ceased. The device's performance should be checked. |
| 54 | Signal from the Ocan-corrector sensor. |
| 55 | This combination reports that when driving a car, in particular - with high load on the Motor VAZ 2115 in the injection system is impoverished fuel mixture. In this case, the signs of breakage may be the same as in the case of codes 44 and 45. |
| 61 | The oxygen sensor broke. To restore the system operation, you should replace the sensor. |
Errors controllers
| Combination | Decoding |
| R0101-R0103 | These combinations mean. In particular, the signal can be elevated or low. The device should be replaced. |
| R0112-R0113. | It is reported about the failure of the intake air temperature sensor. It is necessary to check the wiring, especially in places where the wires were repaired. Apparently, the on-board computer tries to inform you about the occurrence of short circuit or cliff. |
| R0116-R0118. | These error codes indicate a malfunction of the antifreeze temperature sensor in the system. As a rule, in such cases, it is better to check the wiring better to begin with, and if everything is in order with the chain, it is desirable to replace the sensor directly. |
| P2138, p2122, p2123, Р0222, Р0223 | These error codes indicate the incorrect operation of the accelerator pedal position control. |
| Р0201-Р0204 | When such combinations appear, the on-board computer is trying to inform the car owner about incorrect work one of the injectors. In particular, the circuit breakdown or short circuit can be fixed in the system. |
| R0130 - R0134. | One of these combinations of numbers may mean a malfunction in the functioning of the control sensor of the oxygen. To restore the sensor, check the circuit for cliffs and short circuits or it is worth replacing the device. |
| R0136-R0140 | Error data means incorrect operation of the diagnostic oxygen control sensor in the injection system. As in the previous case, errors can mean incorrect operation of the device or electrical wiring fault. |
| Р0217. | Indicates engine overheating internal combustion. In this case, malfunctions can be covered both in the engine itself and in:
|
| Р0326-Р0328. | On-board computer VAZ 2115 informs the car owner about the detonation sensor breakdown. In particular, such combinations may indicate not only the output of the sensor, but also the incorrect signal coming from it to the control unit. |
| Р0340-Р0343. | Such combinations indicate a breakdown of the position control sensor distribution Vala VAZ 2115. In particular, errors can mean:
|
| Р0351, Р0352, Р2301, Р2304 | The data of the combinations mean the incorrect operation of the ignition coils, namely, it is about the incorrect signal entering the on-board computer. Also, these combinations may indicate the cliff in electrical wiring or a short circuit, recorded in the chain. |
| Р0422. | There was a breakdown of the device of the neutralizer. |
| Р0691, Р0692. | There was a breakdown of the first fan relay of the cooling system. |
| Р0693, Р0694. | The on-board computer recorded a breakdown of the second relay of the cooling system fan. When undime replacement The fuse is possible boiling coolant. |
| Р0485 | The control voltage from the cooling fan enters the control unit. |
| Р0560-Р0563. | The control unit registered too low or high voltage of the aircraft. |
| Р0627-Р0629. | The combinations data may indicate both the incorrect signal from the fuel pump and the breakdown of the relay responsible for the operation of the aggregate. It is worth noting that when the fuse breakdowns, the vehicle work will be impossible, since neither will start the engine. |
| P1602. | 1602 is a widespread VAZ error. Malfunctions are registered in the operation of the controller of the DVS control system. |
Reset mistakes
If you have discovered and eliminated a malfunction, then it needs to be erased from the side of the on-board computer. To do this, repeat the following actions:
- Mustle the engine and turn off the ignition.
- Disconnect the terminals from the battery.
- Wait a few seconds and connect the terminals back to the battery.
Video "Reset Motor Error VAZ"
This video describes the process of resetting a combination of errors for cars VAZ of the tenth family.
Please note that when self-diagnosis, the on-board computer has habit of folding the combinations obtained.
For example, often car enthusiasts are looking for information about the failure of 10, under which the errors 2 and 8 are hidden.
How to decrypt codes
The listed combinations occur extremely often. If another digit is displayed on the display, refer to the technical documentation of the car. In most cases, it is necessary to test the electrical circuit to detect the breakage. Since most often problems arise in it, and errors are due to incorrect processing of query sensors.
Errors that may produce an injector
In a separate group, it is worthwhile to display the error of the fuel injection unit and combinations associated with engine malfunctions. With self-diagnosis, they can appear as follows:
- 35 - failures in the operation of the idle sensor, it will be necessary to replace it;
- 43 - incorrect signal from the detonation regulator, often appears when cliffs in the electrical circuit;
- 44 and 45 - malfunctions in the injection system, fuel is overly enriched or, on the contrary, depleted;
- 54 - The Octane-corrector controller does not respond;
- 55 - by high revolutions fuel mixture depleted.
It is worth considering the combination 44, 45 and 55 in more detail. If the fault is hidden not in the sensors themselves, then you can notice the signs of it from the engine side:
- it will troop;
- during gear shift, jerks can be felt;
- in rare cases, VAZ-2115 simply stalls without reasons.
If you have noticed one of these combinations on the display, it is worth conducting a more thorough diagnosis of your car. In some cases it may be necessary overhaul. Those who have faced the problems described, it is worth contacting the service station, because the car will not often repair on their own.
Invalid data for self-diagnosis
According to the reviews of the experienced VAZ-2115 owners, the on-board computer cannot be called perfect on this model. They recommend not entirely relying on self-diagnosis, since the data obtained with it does not accurately indicate the problems of transport nodes.
The basis of the self-diagnosis system is taken to process signals from common sensors. They are unable to transmit specific data that is necessary to accurately determine the problem. Imperfections are almost in each node. A few controllers are located on air system and fuel injection mechanism. They can malfunctions both with a serious breakdown and when the conductors' breakdown.
Most often, the owners of the VAZ-2115 have to deal with incorrect operation of the generator. It is this unit that often gives too low or high voltage, which causes malfunctions in all controllers.
Modern cars are abundantly filled with all sorts of electronics. Therefore, computer diagnostics has become quite ordinary phenomenon when repairing a car.
Not exceptions are VAZ 2110 cars with injection engines, to check which with the help of computers, special adapters and software can be even their own hands.
Why do you need diagnostics
Let's see for a start, why to diagnose malfunctions and whether it is specifically required for your car.
The main advantage of the diagnosis is the ability to save money, time and modern nerves. If the car begins to retire itself inadequate, some extraneous sounds appear, violated stable work Engine, then there are two options:
- Examine all systems manually by dismantling and testing, spend a bunch of time and nerves. The probability of finding the cause of the breakdown is far from 100%.
- Conduct computer diagnostics with your own hands by connecting a special adapter, a cable to a computer. The program scans the car and can give the appropriate error codes. After examining our material with error codes, you will easily find the reason why the car started to behave abnormally.
Should I contact a hundred?
The quality of diagnostics to a hundred is often not much different from an independent check. The presence of an adapter and cable for connecting the device allows you to deal with problems of your own auto without outside intervention.
By contacting the service station, you can diagnose the same equipment, only at the same time you will request a decent amount of money. If you do not control the checkpoint yourself, the masters can declare the detection of other errors that do not actually exist.
The result of the appeal to a dubious STR for the purpose of diagnostics may be serious financial costs and a long lack of a car at your disposal.
The only option when it is necessary to contact the car service - this is the lack of equipment for the diagnosis and the presence of good acquaintances among auto mechanics.
What is necessary for work
If you decide to diagnose your VAZ 2110 faults yourself, then you will need several basic things for this work.
|
Device |
Features |
|
This is a kind of chip, enclosed in the body. It allows you to connect the "brains" of your car with a computer and issue the appropriate information on the laptop or tablet screen |
|
|
Used to connect the adapter with a car and computer. Usually comes with an adapter |
|
|
A computer |
When choosing a computer, rejoice at what you have is a stationary PC, a tablet, a laptop. Better portable computer, since it is difficult to connect cars with a stationary PC. Do not suit for diagnostics cables more than 5 m long, so taking into account this when connected to a PC |
|
The required software can be found on the Internet, or take the software provided with the adapter. There are no problems with searching for NO today. |
Choosing an adapter and cable, take into account the features of your car. Not all universal adapters. For VAZ 2110, an example of an excellent adapter is ELM327. We will talk about him later.
How it works?
Now we'll figure it out how it all functions together and propagate the car as you can dig.
- The diagnostic program sends signals through the COM port through the adapter to the car controller.
- The controller sends information in response.
- The program conducts the processing of the received data by issuing the corresponding result on your computer screen.
- Data exchange is carried out according to the relevant protocol. Depending on the car manufacturer, the protocol may be different, have its own features.
- To simplify the diagnosis, many manufacturers use the ODB II Universal Protocol. Its possibilities are limited and adapted not for all cars. It is suitable for the VAZ 2110 model perfectly, since the tent are not distinguished by an increased electronics in contrast to more modern cars.
- In the case of the VAZ 2110, the program on the computer screen will display the result in the form of error codes. It is enough to open the material where we described the error codes for the VAZ 2110 to understand exactly what breakdown fell on your car. Next, appropriate actions are being taken to eliminate them.
The essential advantage of the diagnosis is the fact that after it you know exactly, with a malfunction of which nature you are dealing. You do not have to sort out half the car to find the source of the problems.
Types of diagnosis
Computer diagnostics of the car can be divided into three main species, one of which directly to the VAZ 2110 does not have a relationship.
- Check suspension. It must be carried out if the rubber began to uneven wear out or extraneous sounds are heard when moving. Diagnostics will determine the reasons for the demolition of the posterior and the front axle, which you can see when the speeds can be rotated.
- Engine check. The main share of diagnostic events falls on power units. Computer and adapter will help you if instability is observed idling, the machine is hardly started, the fuel consumption increases, power drops, etc.
- Check automatic transmission. Since the VAZ 2110 is not equipped automatic box Transmissions, no sense in conducting its diagnostics.
Connectors
You decided to diagnose. But what and where to connect?
On the VAZ 2110 connector for computer diagnostics (CD) is located below the steering column to the right of the driver. The connector is called OBD. This information greatly simplifies the search for a suitable adapter.
To check, you must perform the following sequence of operations:
- The adapter is inserted into the OBD steering slot;
- The computer should already be included;
- When the shoe is connected to the adapter, you need to turn on the ignition. Without power, the program will not work and read the data;
- Next, connect the program with which testing is performed;
- If all the elements are workable, the electronics of the computer will be displayed on the computer monitor;
- Start checking.
Plotovka
Since it requires a diagnostic shoe to verify, that is, OBD, it will not be superfluous to learn about the peculiarities of its pinout. So you can easily figure out how to connect:
- Contact A - is responsible for the mass connection;
- Contact V - Required to connect L-LINE. Note, not all cars have this contact;
- Contact M - serves to connect K-Line;
- Contact N - Power + 12V;
- Contact G - controls the operation of the gas station.
Separately, we will introduce you to the ELM327 adapter, with which many owners of VAZ 2110 perform their own full diagnostics.
ELM327 is one of the latest OBD developments. This scanner applies auto checks using a computer. The key advantage is that the device supports all the well-known OBD protocols and interacts with many diagnostic programs. To communicate, a USB cable is used to communicate with the computer.
Software for ELM327 is predominantly free, although a certain software is only available for payment.
The adapter operation is possible on computers with different OS. Namely:
- Windows;
- MacOS;
- Linux;
- Palmos;
It is possible to fully disclose the scanner capabilities only at the expense of correctly selected software. For self-diagnostics, the software for the scanning of the gearbox and the engine is available for free. Commercial versions of programs allow you to additionally check other vehicles of the car.
Main features
Let's get acquainted with the possibilities that the ELM327 microcircuit provides:
- Reads error codes, car faults;
- Displays codes and their description;
- Exports data to the printout, if necessary;
- Removes error codes;
- Displays data in the metric measurement system and system used in the US;
- Writes, saves data, builds graphs;
- It has an overclocking counter from 0 to 100 km / h, which allows you to diagnose on the go.
Checking many parameters of the car's work should be carried out on the go. Not all adapters are adapted for this, so it is important to choose the equipment that meets your requirements.
Equipment
By purchasing such an adapter, you get:
- High-precision adapter based on the ELM327 processor;
- OBDII cable;
- Cable for connecting to a computer;
- Disk with free software.
For the adapter and receive information, it is not necessary to have a powerful computer. The parameters of the simplest laptops are enough to carry out the diagnosis of VAZ 2110.
An independent CD allows you to seriously save, get objective information about the state of your car, as well as save yourself from unnecessary financial costs, which, when handling a hundred, be sure to appear.
Greetings you ladies and gentlemen! At the very least, I really want to believe that there are also a fair sex representative among you! If you are the happy owner of modern classics in the form of a car brand VAZ 2114, then sooner or later, you will have to face the errors of the control system of the ECU. Help to understand these unknowns for an ordinary driver combinations - the main goal of this article. VAZ 2114 errors, as in many others vehicles - This is the main tool for the message to the driver of a malfunction of any mechanism, the unit, or the automotive system assembly.
Definition of malfunction on your own
Of course, we are like real drivers, always strive to solve any problem own hands. Well, do not like you when someone else's uncle treats your "swallow" and I understand you perfectly perfectly. However, if we consider the question of the on-board computer, then everything is somewhat different, but in certain cases it can cope on your own. Immediately I warn you: do not listen to the pessimists who will prove with foam on the lips that the computer errors do not win. But remember once and for all, error codes will differ from the hundred options, because by and large we will test dashboardwithout resorting to the help of the very "bortovik". Instead of a number with a four-digit value, we will have a double-digit.
Before you tell you about various combinations, perform a few simple actions. They will help not only determine the firmware version, but also to find out about the faults. Self-diagnosis, starts with these actions!
- Find the odometer button and hold it.
- Turn the key to position 1.
- Release the odometer (start running the arrows).
- Click on the odometer and immediately release (information about the firmware appears).
- Again, repeat the previous steps, after which, when the fault persuasion, you will see their error codes.
In the case when the Check Engine lamp is burning, it means a failure in the electronics system, then do not do without specialists. In other cases, after these actions, using the following information, it will be possible to read errors. Combinations that may appear on the instrument panels:
- 1 - failure of the microprocessor;
- 2 - faulty fuel level sensor;
- 4 - increased voltage in electrocups;
- 8 - low voltage in electrocups;
- 13 - there is no signal from the oxygen indicator;
- 14 - elevated coolant temperature;
- 15 - reduced coolant temperature;
- 17 - Low voltage onboard network;
- 19 - a malfunction of the sensor determining the position of the crankshaft;
- 24 - failed a speed sensor;
- 41 - phase sensor error;
- 51 - constantly storage device, it is unstable;
- 53 - co-potentiometer is faulty;
- 61 - The lamb-probe is not working correctly.
Even by removing the fault, the corresponding codes will still go to the error panel. "How to throw out these testimony?" You ask. Yes, very simple! We turn on the ignition and disconnect the plus terminal from the battery for a few seconds.
After that, check the result of almost 100% warranty, which, with a corrected error, the problems will disappear. Another nuance that can mislead you, this is the addition of errors. That is, if there are several of them, for example: 24 and 41, then you will see the number 65.
Diagnosis Special Equipment
To conduct a "examination" of directly onto the on-board computer, the most likely will not be possible. Of course, if you have special skills and there is a special laptop, then it is quite real and telling how to check this node you do not need. However, in most cases, you have to contact specialized Services. There are so-called glitches. In other words, the situation where the information demonstrating the computer does not respond true. Of course, like any electronics, "bortovik" can give a failure. I hurry to calm you - it is more exception than the rule. If somehow it was still possible to lure the ill-fated four-digit code from the system, although the answer to the question of how I already gave it to see. But still consider the most important faults that can define on-board computer:
- 0102, 0103 - The mass flow sensor was faced;
- 0122, 0123 - The throttle position sensor was faced;
- 0300 - ignition pass, lead to problems when starting the car;
- 0335, 0336 - failure of the detonation sensor;
- 0480 - the cooling fan does not work;
- 0505-0507 - the idling sensor failed;
- 1500 - a break in the fuel pump circuit;
- 1602 - the most popular error, means disappearing the power of the on-board network;
- 1689 - means of incorrect data coming from onboard computer, including error codes;
- 0217 - Engine overheating.
Of course, it is only a small part of the five sheets of A4 format of such codes. But at the most common moments, I pointed your attention. I advise everyone from you to acquire my own table where such decryption is presented. I want to warn right away, there are no codes of the injector breakdown, but all adjacent mechanisms are under strict control of the on-board computer. I want to believe that this article I achieved the tasks and helped at least one of you. Believe me, I will be enough. Well, okay, something suffered me. Good and good and new meetings!
