Every owner of a car with an engine fuel injection system sooner or later encounters errors in the operation of the main power unit. If a particular system malfunctions, a special indicator lights up on the instrument panel. Some drivers ignore the persistent warning and continue to operate the vehicle. Experienced car enthusiasts, at the first mention of an error, are sent to undergo diagnostics, which allows them to correctly determine the cause of the malfunction and select the most effective ways to eliminate it.
Renault Megane 2 is one of the most common representatives of French engineering. A stylish and modern car is popular among domestic drivers. Despite the fact that Renault Megane 2 has good technical characteristics and boasts a long engine life, sedan owners also encounter errors DF080 and DF119. How to decipher them and what are the ways to eliminate them?
How to conduct self-diagnosis?
You can decipher the error meaning using special equipment. Many service stations today are equipped with all the necessary components to carry out high-quality diagnostics. However, such work can be done independently if you have the proper equipment. In most cases, an inexpensive device operating via the OBD-II interface is sufficient. Using such a device, it is easy not only to detect and decipher an error, but also to control many parameters.
A console to an on-board computer is one way out of this situation. For a more detailed scan, it is best to arm yourself with a laptop and an OBD-II adapter. Today you can also purchase a wireless analogue of the device, with which you can decipher the error code on Renault Megane 2 even using a smartphone. In general, there are a lot of ways to diagnose and solve problems that arise.
Error DF119
Cars of the Renault Megane 2 family are equipped with a multiplex network that allows you to diagnose the system using the on-board processor, or using the above-mentioned external scanners. DF119 stands for camshaft sensor error. To solve this, you first need to check the camshaft teeth located under the valve cover and the teeth from which the sensor takes readings. If the teeth and marks are in the correct position, the DPRV itself should be checked for functionality. To do this, just arm yourself with a multimeter.
Sequencing:
- Set the multimeter to voltmeter mode.
- Measure the input voltage - it should be at least 12V.
- Measure the power supply of the contacts: 12V on the first, 0V on all others.
- Disconnect all sensor wires and connect a measuring device to the output.
- Select the “resistance” mode and hold a metal object near the sensor.
- Constancy of readings is evidence of sensor failure.
How to remove error DF119 on a Renault Megane 2? If the sensor is inoperative, it should be replaced with a new one. It is also worth checking all wiring and contacts. After replacing the mechanism, the electronic unit needs time to rescan the system. Therefore, during subsequent trips after the repair, the error indicator will still appear on the instrument panel. Some drivers try to resolve the error by disconnecting the battery. Such manipulations sometimes give a positive result, but if the problem has not been solved, the indicator will light up again over time.
Error DF080
If there are problems with the phase regulator, the scanner often displays DF080, indicating that there have been changes in the characteristics of the camshaft. What to do in such a situation? The phase regulator allows you to determine the position of the camshaft. By closing, it thereby allows you to switch the operating mode of the motor. It is easy to determine its malfunction; it is enough to measure the level of consumption of fuels and lubricants, or its failure will be clearly manifested in the failure of traction.
On Renault Megane 2, the phase regulator fails most often due to a faulty valve or oil seal. If the scanner displays DF080, then the first thing you need to do is check the RFG. To do this, just do the following:
- Using a hexagon, remove the decorative insert on the power unit.
- Disconnect the sensor contacts.
- Dismantle the RFG.
- Carry out a thorough visual diagnosis.
Cracks, corrosion and other defects indicate that the mechanism needs to be replaced. If the problem has not been solved, then the cause should be sought in the camshaft position sensor, the scanners also respond to faults by displaying DF080.
Error DF624
DF624 most often signals that there has been a failure in the multiplex circuit of the protection and switching unit. This means that it is necessary to check all contacts of the battery and fuse box. It would be a good idea to inspect all air and fuel filters, which are often the cause of the appearance of DF624. If the scanner displays a message about non-compliance with environmental standards, then it is worth inspecting the catalyst and. In some cases, cleaning the throttle valve helps.
It is necessary to disconnect the crankcase ventilation hose pipe, and then disconnect the block from the throttle assembly. The assembly itself is dismantled by releasing the four mounting bolts. The throttle body can be cleaned with gasoline and finally treated with silicone spray. Install the mechanism in the reverse order.
Error DF025
If among all the alerts there is also a place for DF025, then you cannot do without inspecting the ignition system of the Renault Megane 2. There is only one solution in this situation - check the glow plugs. First of all, the resistance of each glow plug is measured, which must be at least 2 ohms. If the spark plugs are in good condition and turn out to be fully suitable for further use, all efforts should be directed toward measuring the battery voltage and inspecting the 32-pin connector.
Procedure:
- Warm up the engine, then remove the spark plugs.
- Blow away dust and dirt from the area where the spark plug is installed.
- Use wd40 to soak threaded connections.
- Inspect the spark plugs and check their functionality.
Sometimes the problem can be solved by replacing the preheating mechanism and wiring.
P0010 signals that there has been a malfunction in the valve timing system drive, or there has been a malfunction in the functioning of the electrical circuit. Initially, the condition of the filter mesh on the phase regulator valve and the degree of contamination are visually assessed. If you change the engine oil in a timely manner, premature clogging of this element with dirt is unlikely, but in some cases it is appropriate. As in the case of the DF080, it is important to check the functionality of the RFG itself; often replacing it becomes the solution to many difficulties.
In order to have detailed information about the car during diagnostics, it is important to have an electrical diagram at hand. You can find it in the vehicle's operating manual. You should not immediately resort to radical methods of eliminating errors, replacing capricious mechanisms. Often faulty connectors and oxidized contacts become the culprits of the car owner's headaches.
Most owners of Renault Kangu, when looking for information about typical errors of this model, know well what they are talking about. And for beginners and drivers who have not yet had time to deal closely with the malfunctions of the purchased car, we note that every vehicle coming off the assembly line since 1996 has a special OBD-II connector. With its help, you can diagnose the car and get a report on errors and malfunctions.
In some cases, car owners can use a special OBD-II scanner ELM327 with wireless access to the on-board system, as well as download and install special software for sending data to a mobile device. This device is multi-brand. But if desired, equipment from any other company can be used for diagnostics - from professional to simple.
According to the standard, OBD-II has certain operating modes and, accordingly, error codes. The on-board PC stores information about them by default. Data can be removed by connecting to the connector using a wired or wireless adapter.
Renault Kangoo diagnostic connector and scanners
Beginners who have never encountered a breakdown in their Renault Kangoo should know where the diagnostic connectors are located on cars of different generations. As you know, there were two of them.
In Renault Kangu I, the diagnostic input is located in the area of the fuse box, in a separate compartment. It can be found under the steering column, above the pedals on the driver's side. The connector is located in a protected black box with a lid slightly to the right of the fuses. It must be said that the test input is located in this place for all models of this manufacturer until 2003-2006.
In the Renault Kangoo II, the connector is located directly below the armrest and is covered with a small plastic plug. To connect a wireless scanner, you will need a Bluetooth adapter. In this case, the scanner or phone will receive the data.
If you choose an adapter, then one of the multi-brand options may be suitable for your car. There is also a wired scanner on sale, called Renault Can Clip, which is not inferior in functionality to other devices.
Please note that if you use a non-branded scanner on machines before 2006, there may be installation difficulties. The fact is that many are connected to the bottom connector, and data is removed from the top.
Operating modes and OBD-II codes
The OBD-II connector can be made according to two standards. Earlier machine models are oriented to the SAE J1979 standard, more modern ones - to J2190. There are modes defined by the standard, and there are also those that can be determined by the manufacturer. Moreover, the manufacturer may not support some of the standards.
Typically, the third mode 0x03 is responsible for reading fault codes, that is, information can be downloaded by connecting to the on-board system. Codes for the Kangoo model are published in company repair documentation and are available to a wide range of users.
How to decipher a car breakdown code?
All standard error codes are divided into two sets: spoken by OBD-II (reported by the on-board Multitronics PC) and unspoken, that is, proprietary to the Renault Kangoo, or rather to the Renault brand. Multitronics is an on-board trip computer that fully automates communication with your car. It connects to the OBD-II connector.
In rare cases, the manufacturer separates error codes by car model. Please note that any new modification may contain an improved set of codes. Renault has specific repair lists containing this information.
Errors spoken by the on-board PC are available when the mode is activated. Here are additional codes used by the French concern Renault:
- 3500. The integrity of the electrical wiring responsible for blocking the engine during an attempt to steal has been compromised.
- 3501. There is not enough data to maintain the specified microclimate (failure to communicate with the system).
- 3502. Electronics does not read data coming from cruise control (BVA operation is disrupted).

- 3520. Light signaling electronics when the permissible temperature of the coolant is exceeded (open circuit).
- 3521. Electrical circuit of the indicator indicating that the permissible temperature of the engine cooling liquid has been exceeded.
- 3522. Error in the electronics that control the idle speed setting (diagnostics reveals that it is “shorted to positive bat”).
- 3523. Malfunction of the electrical wiring leading to the electronic pedal (broken).
- 3524. Malfunction of the electrical wiring leading to the electronic pedal (shorted to plus 12V).

- 3530. Malfunction of the climate control module (fault in the circuit).
Standard (spoken) codes can be found on the official Multitronics website, where you can also familiarize yourself with the capabilities of this device.
If your car is equipped with an on-board computer, then you can read the error codes to find out why the car is not working correctly. In this case, you will need to decipher the codes that appear during error diagnosis. Today you will learn how Renault Logan error codes are deciphered, what they are and how they happen.

Car diagnostics
If you decide to decipher the error codes of your Renault, be it Logan, Megan or even Premium, then you will need to first make a diagnosis. There are several ways to do this:
- A trip to the service station. Specialists will carry out diagnostics using equipment, in particular a scanner, and provide you with error codes present in the system of your car. This procedure costs on average 1 thousand rubles (500 hryvnia) and more.
- Diagnostics using a computer. To do this, you will need a special scanner, which costs 5 thousand rubles (2,500 hryvnia) on average and more. The procedure is not cheap and is more suitable for those who like to “dig” into technology.
- New on-board computer. Just in case you are not satisfied with the native BC installed at the factory. You can purchase a more functional one that will alert you not only about errors, but even about fuel consumption.
- Connect your smartphone to the on-board computer. Having a functional phone, you can connect it to the OBD-2 connector and start deciphering codes directly from your gadget. For this you will need a Bluetooth adapter. The asking price is up to 1,000 rubles (500 hryvnia).
Let's look at the Renault diagnostic process using the ELM327 adapter as an example.
- First, find the OBD, which is located in the glove compartment of the car on the right side.
- Then insert the purchased adapter into and place your mobile device next to it. By the way, you can use not only a phone, but also a tablet computer. Download and install the necessary software on it in advance. Depending on the phone model, the names of the programs may differ. In practice, most domestic car enthusiasts diagnose their Renaults using the Torque program. It can be easily found and downloaded on the Internet.
- Turn the key in the ignition and start your car.
- Next, turn on your phone's Bluetooth feature and launch the software you decide to use for diagnostics.
- Wait a few minutes for your phone to begin syncing with the adapter you inserted into the diagnostic socket. When the utility connects to the ELM327, the phone screen will show the parameters of your car's engine in working condition.
- To understand why the Check Engine light comes on on your car’s dashboard, go to the appropriate section in the program window. Then the utility will begin to read combinations of faults from the memory of the on-board computer. If the software has detected at least one failure, a combination of letters and numbers with an explanation will be displayed on the mobile phone screen. Only by deciphering the code will you be able to replace a non-working component.
Decoding codes
Vehicle fault codes consist of five characters. The first is a letter, and then there are numbers. As for the letters:
- P - means that the malfunction is related to the operation of the engine or gearbox;
- B - literally translated means body malfunction. Here we are talking about electric windows, seat adjustments, car central locking, etc.;
- C - indicates a malfunction in the chassis system;
- U - means identifying a breakdown in the operation of electronic systems.
- in the second position, the number 0 indicates the general code for the OBD-2 diagnostic connector, the number 1 or 2 means the vehicle manufacturer code;
- in the third position, numbers 1-8 mean breakdowns in the fuel system, ignition, idle system, transmission, etc.;
- the fourth and fifth positions indicate the serial number of the malfunction.

Engine malfunctions
It should be noted right away that this material provides an incomplete list of code combinations that you can see during diagnostics. We consider only those that are most often encountered when checking Renault. In addition, with the release of new models from the French manufacturer, the number of codes and, accordingly, errors is constantly growing.
| Combination | Decoding |
| P0200 | The Renault on-board computer reports that the voltage coming from the fuel injector is too high or low. This combination is especially typical for Premium and 420 dci models. It is necessary to check the injector circuit or replace the element. |
| P0201 - P0104 | One of these combinations means a short or open circuit in the injector circuit of one of the four cylinders. You need to check the chain or replace one of the injectors - the one that has failed. Such errors are typical for Renault Logan and Megan cars. |
| P0230 | The control unit notifies the car owner that the fuel pump fuse voltage is too high or low. The first step is to check the circuit, but it may be necessary to replace the fuel pump itself. |
| P0301 - P0304 | One of these combinations indicates the occurrence of misfires. In particular, we are talking about one of the four cylinders. Such errors are especially common when diagnosing Renault Logan and Megan cars. To correct the code, you need to check the performance of the engine cylinders. |

How to check?
There are several ways to check problems related to the operation of the on-board computer in cars of the Premium dxi 460, Duster, Kengo, Megan and others:
- At a service station. For a fee, specialists will diagnose all systems and components of the machine using a computer and scanner. The car owner will be provided with information on existing problems in the form of letter and number combinations or recommendations from service station employees. The average cost of performing this procedure by specialists is about one thousand rubles.
- Independent testing of systems in Simbol, Scenic, Traffic, Fluence and other models can be done at home using a computer, adapter and program. The cost of the scanner will be from 2 to 5 thousand rubles on average, depending on the model. Having purchased such a device, the car owner can perform diagnostics at any time to determine problems. The best option for those who solve device problems on their own.
- Installation of a new on-board computer. If the functionality of the existing BC does not suit the owner of a Renault Magnum Mac, Laguna, Logan 16 valves or another model, you can install a new, more modern device. Such on-board computers warn car owners not only about problems, but also about other parameters, for example, fuel consumption.
- Perform self-diagnosis on the dashboard. In this case, the display will display fault codes in a different format than the computer check. This method is less accurate, but it still allows you to determine the main damage.
- You can connect a mobile device on the Android or iOS platform to the diagnostic output in Renault Default Capture, Logan, Premium dxi 270, 380, 440, 450 or 460 cars. Having a smartphone or tablet will allow you to connect to the diagnostic connector and check all systems using the gadget. For diagnostics, you will need a special adapter that works via Bluetooth. The cost of the device is about one thousand rubles.
The Useful China channel showed how to check car systems using an adapter.
Self-diagnosis
The self-diagnosis procedure will not identify minor errors, but it allows you to identify the main problems associated with the operating state of the systems:
- Before the test begins, the key is installed in the ignition switch.
- After installation, you need to hold down the odometer button on the dashboard, designed to reset the daily mileage.
- When the button on the dashboard is pressed, the ignition is activated. Within a few seconds, numbers will appear on the dashboard. Once the button is released, the testing process begins. All the arrows will begin to move quickly along the scale, we are talking about the speedometer, tachometer, engine temperature and fuel remaining sensors.
- Renault cars use five modes with information; to move to the next one, you need to press the mileage reset button. The first screen shows the firmware version of the control unit, the second screen activates all indicators on the screen, and the third displays the remaining fuel in liters. If there are problems with the operation of the on-board network, then dashes will be displayed on the dashboard display. The fourth screen displays instantaneous fuel consumption. At the fifth stage, all problems that exist in the operation of the vehicle’s systems and components are shown, but this mode is available only to car owners whose cars have an on-board computer with firmware 6002 installed. It will not be possible to accurately determine all problems, since this screen allows you to identify problems in the functioning of level sensors antifreeze, fuel, as well as an information system about gasoline or diesel consumption.
1. First diagnostic display on the dashboard 2. Self-diagnosis of all screen components 3. Third display showing the remaining fuel in the tank 4. Instant fuel consumption screen
You can find out more accurately about the state of the systems using smartphone diagnostics.
Let's look at the process of performing this task using the ELM 327 adapter:
- Locate and provide access to the OBD diagnostic output. Depending on the year of manufacture and model of the car, its location may be different. Look for the connector under the steering wheel, ashtray, or in the glove compartment.
- The existing adapter must be installed in the diagnostic connector, and place the mobile device next to it. It is possible to carry out the test using a smartphone or tablet; you must first download a diagnostic utility onto the gadget. The name of the applications may be different; here you need to focus on the mobile platform and model of your phone or tablet. In most cases, accurate diagnostic results can be obtained from the Torque program. The utility is downloaded from the Internet and installed.
- The next step is to turn the key in the ignition and start the power unit of the car.
- The Bluetooth option is activated on the mobile device and the diagnostic application is launched.
- Within a few minutes after starting the program, the phone will synchronize with the adapter installed in the diagnostic connector. After successfully connecting the devices, the gadget’s display will display data with the machine’s engine parameters.
- Use the program interface to troubleshoot problems. In the testing section, click on the start diagnostics button. The process of reading error codes from the memory of the electronic control unit starts. If there is at least one malfunction, special codes will be displayed on the gadget screen. The resulting combinations must be decrypted, this will allow you to obtain accurate information about problems. In accordance with the malfunction, the failed part is repaired or replaced.
To remove faults from the memory, you need to disconnect the battery terminal for a few minutes.
Decoding codes
Below are lists with explanations of problems in Russian and recommendations for troubleshooting.
User TRAKSITE showed in the video how the procedure for reading and decoding trouble codes on a SCANIA truck is carried out.
Engine problems
First, we will analyze the decoding of fault symbols for Renault Master, Megane, Premium and other car models.

You can learn about troubleshooting the operation of the power unit and removing errors from the memory of the control module from the video filmed by the Xeonnick LIVE channel.
Problems with electrical wiring
Now let's look at error codes specific to the vehicle's electrical network.
| Code | Decoding |
| P3500 | The car owner is warned about failures that have occurred in the electrical power supply circuit of the car alarm. In practice, such problems lead to the fact that if the car is broken into, the power unit will not be blocked, as a result of which the car can be stolen. |
| P3501 | The control module has registered a loss of communication with the climate system. It is necessary to check all electrical circuits for possible breaks and short circuits. |
| P3502 | Malfunction of the electrical circuit with the cruise control system control module. The error is only relevant for machines that have it. |
| P3503 | The control module has registered a loss of communication with the ABS system unit. The system will not operate until the fault is corrected. To restore the signal, the electrical circuit that goes from the ABS module to the electronic unit is diagnosed. Often a malfunction occurs at soldering points; such sections of the wiring must be carefully checked. |
| R 3504 | Problems associated with the electrical circuit require diagnostics. |
| P3505 | The control module has registered a lack of communication with the fuel rail. All electrical circuits are checked for possible short circuits or damage. First of all, adhesions are diagnosed. |
| P3506, P3507 | The control module has detected a short circuit to ground in the electrical circuit of the coil of cylinders numbered 1 and 4. An integrity check is performed, damaged or defective wires are short-circuited. |
| P3508, P3509 | There is a similar problem with the wiring of the ignition coil in cylinders 2 and 3. The steps to detect the problem are identical. |
| P3511 | Problems in the electrical control circuit of safety devices, most likely meaning a short circuit. |
| P3515 | Problems have been reported in the electrical circuit of the canister purge valve. The reason may lie in a short circuit or damage to the electrical circuit. Detailed troubleshooting is required. If the insulation breaks, the defective area must be replaced or re-wrapped with insulating tape. |
| P3520 | The car owner needs to find the location of the break in the electrical circuit of the emergency refrigerant temperature indicator light in the cooling system. The reason may be a short circuit or a break. |
| P3522 | A short circuit has been detected in the electrical circuit of the idle speed controller. The problem will cause the internal combustion engine speed to fluctuate, and in some cases the engine may “triple”. If the electrical circuit is intact, then the controller must be replaced. |
| P1546 | Depending on the model, the decoding of the code may be different. The cause may be a defect in the AC compressor clutch signal circuit. Or the problem should be found in the wiring of the second exhaust gas controller. |
| P0335 | Problems in the electrical circuit of the crankshaft position regulator. It is recommended to test the device as well as its circuit. Defects in the form of breaks or damage to the insulation are corrected by replacing the defective sections of the circuit. |
| P0340 | Similar error related to the camshaft. Check the wiring and contacts on the connector. |
| df097 | There is a problem with the multiplex network; the control module does not transmit a signal to the automatic transmission. There may be several reasons. First, the wiring is checked, then the connector and contacts on the control unit and automatic transmission module are diagnosed. The signal problem may be due to oxidation or damage to the contacts. If they burn out, you need to check the voltage level in the on-board network. |
| u1123 | Literally, the malfunction is translated as loss of communication for devices of the second class. It is necessary to test the electrical circuit of the central module. |
| df272 | There is a short circuit to ground in the code line circuit. If the engine is running normally, we recommend checking the control module. It is required to diagnose it, check all contacts and electrical circuits connected to the device. If you hear a burning smell from the unit, it needs to be repaired. |
| R 9007 | Problems have been detected in the electrical circuit of the first frontal airbag on the driver's side. It is necessary to diagnose the presence of an airbag in the steering wheel, make sure that the contacts on the connector are securely connected, the problem may be their arbitrary disconnection. Make sure that the steering column cable is intact and not damaged. If everything is fine with it, most likely the module was locked manually or is operating in crash test mode. The device needs to be replaced. |
The PSA Service channel in a video showed how the procedure for repairing electrical circuits in a Renault car is carried out.
Sensors
| Combination | Designation |
| 1525f328 | Problems have been detected in the operation of the speed limiter sensor. This error code often appears when the regulator contacts are clogged or when the electrical circuit is damaged. It is necessary to check the wiring for defects and clean the connector with contacts. If this does not help, the controller is changed. |
| P1638 | Problems have been reported with the throttle valve. Part diagnostics required. |
| P1122 | Gas pedal sensor correlation reported. It is necessary to check the quality of the device connection, its wiring and contacts. If the circuit is working, the device is replaced. |
| P1264 | This code may indicate several problems. Either this is a malfunction of the fuel level sensor, or water has gotten into the fuel. We recommend draining or using up all the gasoline and then refilling with fuel from another gas station. If the problem persists, check the sensor, in particular its electrical connection. |
| P1372 | Problems with the crankshaft position controller. In practice, the malfunction is often associated with oxidation or contamination of the contacts on the sensor. The device is installed in the engine compartment in such a way that dirt can get on it while driving. When it sticks to the contacts, it makes signal transmission difficult. As a result, a sensor error occurs. If you are sure of its working condition, clean the connector. |
| P2299 | The accelerator pedal position controller has failed to synchronize with the pulse sent by the brake sensor. Device verification required. The cause of the problem may be dirty contacts on the connector. If there is no signal, you need to check the electrical circuit. |
A periodically lit “Check Engine” often indicates low quality fuel poured into the Renault Logan tank. Constant flickering of the check is evidence of failure of one of the two oxygen sensors. If the filling is checked, then replace the spark plugs; their malfunction causes the error indicator to light up. To accurately diagnose problems with the engine, go through diagnostics, or better yet, connect the adapter to the OBD2 connector via a mobile phone and quickly identify the error yourself.
Diagnostics is not a panacea for your car
The engine of a modern vehicle is equipped with an on-board computer, which can detect a malfunction in a sensor or the entire system at an early stage. If the error is minor, we advise you to get rid of the flickering “Check”, because If new problems arise in Logan, the burning light will no longer attract your attention.
Drivers often say that they went to the service center, paid a thousand rubles and left with a clear conscience. Most “specialists” don’t even bother to tell the reasons why the check lighted up, or they use the standard phrases for everyone: “Poor quality of fuel - go to another gas station.” At the service station, be prepared to update the sensors on your car, but as practice shows, this will not save you from the error flaring up in the future, and the malfunction has not gone away.
It's easy to reset the error yourself. To reset the on-board computer memory, remove the terminal from the battery for a couple of seconds. But the check will continue to bother you if you have not repaired the problem in the car, so be sure to get it diagnosed. Renault Logan, older than 2000, is equipped with a diagnostic connector OBD2, which will be needed for this procedure.

Self-diagnosis methods
| Brief description of the method | Comments: what you need and where to go, what’s the catch | Issue price (in rubles) |
| 1. A trip to the service center | Diagnostics are carried out using a scanner, and specialists are required to give you a printout of the error codes found in Logan and reset the ECU memory. If your check flashes and goes out not regularly, but chaotically, then it is advisable to go to the service center exactly at the moment the error flickers. The option is costly, both in terms of money and time. If a new error is detected, you will have to go to the workshop again. | Starting from 1000 and above |
| 2. Purchasing a scanner and installing diagnostic software on a PC or laptop | Today, many diagnostic devices and software have become freely available; the only thing left is to install it on your car. This option is not for everyone, but rather for those who like to tinker with technology. In addition, you need to connect to a laptop, which is not always convenient. Prices for specials the equipment “bites”, which is why a scanner with software is not the cheapest choice for diagnosing a single error. Of course, the investment will pay off in the future. | From 5000 and above |
| 3. Buy an on-board computer | If you are not satisfied with the factory one, then buy a powerful and multifunctional one, for example, in addition to important performance indicators of the power unit, you will see instant fuel consumption. Separate devices are produced for Renault Logan, but not everyone wants to tinker with them. | From 3000 |
| 4. Connection to the OBD2 connector via Bluetooth adapter | Using a modern phone, you can easily decipher error codes directly from your mobile phone. If you bought a used car, then such a thing is a mandatory attribute of your iron horse. The BT adapter is also useful when driving long distances. Later in this article there will be The experience of using this particular device is described in detail. | 950- 1000 |
What is the beauty of the latter diagnostic method:
- the adapter is constantly working and at the slightest blink of the “check” you diagnose errors without wasting time and money on service centers, or you monitor the operating parameters of the Renault Logan engine;
- simple connection/disconnection, for which you do not need to run extra wires that always get in the way. We remind you that it works via BlueTooth;
- There are no changes in the interior, because Half of the drivers have a mobile phone on a stand on their dashboard.
Renault Logan diagnostics via ELM327 adapter
If you have not read codes using this method before, you have a number of questions to which we have answers.
1. Where is the diagnostic connector located? Look in the glove compartment.
2. What do you need? Buy an ELM327 adapter from a special workshop or online. A phone, tablet, for example, based on Android OS, or a smartphone with Windows Mobile is suitable for connection. If you have an IPhone, then there is a program for it, but it is not BlueTooth that will work with it, but WiFi equipment.
3. What are the next actions?
First of all, install the appropriate software on your device. There are a lot of programs, but one of the most common and free to download is the Torque version. Go to Android Market, download and install.
4. Why is Torque popular among drivers? A simple and intuitive interface, additional features, including not only decoding and resetting errors, but also setting up the engine parameters you need, recording a log file with a GPS track, recording performance indicators of the power unit in motion, did their job. Be patient when filling out the primary information for your car: engine volume, technical specification weight, tank volume and others.
Sequence of diagnostics using the adapter:
- Insert the adapter with the OBD2 connector and place the phone on the stand or place it in a visible place.
- Start Renault Logan, turn on the Bluetooth function on your mobile phone, and launch Torque.
- After a few minutes, the program connects via the adapter and displays the engine parameters in operating condition.
- To find out the reason for the flickering of the Check Engine indicator, go to the appropriate subsection. The program reads memory from the control unit. When the slightest malfunction is found, a code is displayed on the mobile phone, followed by its reading and decoding. Torque gives the driver time to search for additional information on the Internet and the opportunity to reset the error. This is how you will get rid of the “check” and find out the reason for its fire.
