Renault Sandero diagnostics, error codes and methods for eliminating them. Renault Diagnostics. The cost of computer diagnostics Renault Entering the diagnostic mode

The Renault-Repair technical center employs unique specialist - COTECH. it certified electrician-diagnostic Renault the highest qualification, who knows everything about the device and repair of Renault cars, and also has an official permit for complex diagnostics.

There are only a few such people, each Renault dealership is obliged to maintain such an employee on the staff.

If KOTECH cannot solve some technical issue, then the next step is a request to the manufacturer's research center. The number of electronic control systems in cars is growing every year, their diagnosis is becoming more complicated. The experience and qualifications of COTECH Renault is guarantor of fault detection with minimal time spent on diagnostics.

The auto concern Renault delivers to the Russian automotive market models that are maximally adapted to our conditions: bad roads, low-quality fuels and lubricants and motor fuel. But even with them, the consumption of gasoline and oil begins to increase over time; there are various knocks, creaks, noises. Any deviations from the normal operation of a Renault car are a reason to present the car for diagnostics at a specialized car service.

Most frequent calls:

• Renault won't start!
• There was an error on the dashboard!
• Reno check is on!
• Alarm not working!

In our technical center, the cost computer diagnostics Renault with the connection of the Renault Can Clip diagnostic scanner and reading errors - 550 rubles. In a short time it is possible to produce diagnostics of most control systems: automatic transmission, engine, ABS/PBS, cruise and climate control, etc. The price of troubleshooting identified during Renault diagnostics depends on the amount of work required.

Simple work- replacement of the sound signal, steering column switch are 500 - 1500 rubles. Works medium difficulty related to troubleshooting in the wiring, with a partial analysis of the car's interior usually - 3000-4000 rubles. Prices on complex work, such as: replacement of wiring, repair of electronic control units begin from 10000 rubles.

In addition to computer diagnostics, the Renault-Repair technical center offers:

• Renault engine diagnostics for gasoline engines (computer diagnostics, cylinder compression check) - 1050 rubles. With the removal of the collector (Nissan engine) - 3150 rubles
• Renault air conditioner diagnostics (downloading freon, evacuating the system, refueling - 1200 rubles, searching for a leak - 800 rubles)
• diagnostics running Renault ( for free, during any work)

Many of us have encountered such a problem as turning on the engine icon (Check engine ...), the appearance of which scares car drivers. Here are 5 of the most common reasons why dashboard check engine light comes on.

The appearance of the engine indicator icon occurs, as a rule, without warning. The reason for the appearance of the Check engine cannot be immediately understood. Even if the car has auto diagnostics (for example, in cars such as,), which scans all car systems for errors and, if any, displays a decryption on the information panel, the reasons for the appearance of an engine check will not be deciphered.

For most drivers, the appearance of this warning icon on the instrument panel means the need to urgently go to a car repair shop to diagnose and fix the cause of the "Check Engine" warning sign. But in fact, in most cases, when the "Check" indication appears, you can, and in some cases, possibly, eliminate the cause yourself without a trip to a car service, which will save you money.

1. Replace the oxygen sensor (lambda probe)

The oxygen sensor in your car is part of the exhaust aftertreatment system that monitors how much oxygen has not been burned in the engine's combustion chamber. This sensor helps to control the fuel consumption of the car. A malfunctioning oxygen sensor (lambda probe) means that car computer receives incorrect data, which can significantly increase fuel consumption and reduce engine power. Most cars have 2 to 4 oxygen sensors. If you have a home automotive error scanner, then by connecting it to the car, you can easily find out which sensor needs to be replaced.

For what reason does the oxygen sensor in the car become unusable: Over time, the sensor is covered with a layer of used and engine oil(oil soot), which reduces the accuracy of reading the sensor indicators for regulating the gasoline mixture and distributing the optimal one. A malfunction of the oxygen sensor in a car leads not only to, but also to an increased content of harmful CO2 substances in the exhaust.

What needs to be done: If you do not change the faulty automotive sensor oxygen, this can lead to the failure of your car's catalyst (may burst), which will result in costly repairs. The cost of new catalysts is very high due to the content of precious alloys. On some cars, there are several catalysts, the cost of which can reach up to 90,000 rubles. So do not pull with the replacement of the sensor. Although the replacement of the sensor and its cost is not very small, but it is not commensurate with the cost of the exhaust gas converter system. You can also save on replacement costs by doing it yourself. Many vehicle manuals have detailed instructions How can I replace the oxygen sensor myself. If you know where the oxygen sensor is located, then it will not be difficult for you to disconnect the faulty "lambda probe" and replace it with a new one. Remember that you can’t pull with the replacement of this important element!

2. Check the fuel filler cap

Many drivers, in most cases, when the "check engine" indication appears, they will think about serious problems in the car's engine, but will not even think to check the tightness fuel system which may be broken due to a defect or an insufficiently tightened neck cap fuel tank. This is a very common reason for the "Check" engine icon to appear.

Reason for the error: Leakage of the fuel system due to the passage of air by the fuel filler cap will increase the fuel consumption of the vehicle, to which the vehicle diagnostic system will issue an engine error by turning on the “Check engine” indication on the instrument panel of the vehicle.

What needs to be done: If, when the "Check" indication appears, your car does not lose power, and there are no sound signs of engine damage (engine knocking, hum, squeaking, etc.), then first of all check the tightness of the gas tank. Your gas tank cap may be cracked or not tight enough. If the cap was not tightened enough, after tightening it all the way, continue driving the car for a while to see if the engine error disappears. To prevent the appearance of an engine check for this reason, regularly check the fuel filler cap. Remember that periodically the cover must be replaced with a new one!

3. Car exhaust catalyst

The car catalyst helps the car to make the exhaust gases of the engine more environmentally friendly. It converts carbon monoxide and other harmful substances into harmless compounds. If your exhaust gas catalyst has become unusable, you will notice this not only when the engine icon (check) appears, but long before that, when the car's power drops by 2 times. For example, when you press the gas pedal, the car, as before, will not have good acceleration dynamics.

What can cause a car catalytic converter to fail: if you regularly service your car, in accordance with the maintenance regulations car company, then the catalyst should not fail. The main reason for catalytic converter failure is not timely replacement a faulty oxygen sensor, as well as irregular replacement of spark plugs at the end of their expiration date. When the oxygen sensor or spark plugs fail, the conversion of carbon monoxide in the catalyst to harmless chemical elements stops, which leads to overheating of the catalyst, which can fail because of this.

What needs to be done: If your catalytic converter has become unusable, then you cannot drive a car, as the engine will not work correctly, warning about this by indicating the engine icon (check) on the dashboard. Also, you will have very much increased fuel consumption, and there will be no engine thrust. Although the replacement of the catalyst is a very expensive repair, there is nowhere to go from the repair. Although there is an alternative in replacing the catalyst with a flame arrester, but this is not a 100 percent option. Unfortunately, if you are not an experienced auto mechanic, then you cannot replace a faulty exhaust gas catalyst yourself. In any case, you will have to contact the auto repair shop. Remember that timely replacement of oxygen sensors and spark plugs protects your catalytic converter from damage!

4. Replace mass air flow sensor

The mass air flow sensor regulates how much air must be added to the gasoline mixture for optimum ignition of the fuel. The sensor constantly informs the car's computer about the amount of oxygen supplied. A defective mass air flow sensor increases fuel consumption, increases CO2 levels in the exhaust gas, and reduces engine power and ride quality. Also, with a faulty sensor, poor acceleration dynamics are observed. In cold weather, a car with a faulty sensor does not start well.

What are the reasons for the failure of the mass air flow sensor: Most sensor failures occur due to improper installation of the air filter during its scheduled replacement. Also if not changed regularly air filter as required by regulation Maintenance vehicle recommended by the manufacturer, the mass air flow sensor may fail.

What needs to be done: Theoretically, you can drive for a long time with a broken mass air flow sensor (several weeks or months). But you will notice that the longer you drive, the more fuel consumption increases. Replacing the sensor in a car service is not so expensive, since the work itself does not take much time and is quite simple. The main costs are associated with the cost of the sensor, which for some car models can be 11,000-14,000 rubles if it is an original sensor or up to 6,000 rubles if it is an analog substitute. Self-replacement sensor is very simple. But due to the low cost of replacing the sensor, you can entrust this work to a master in a car service. Remember that it is necessary to change the air filter regularly, following the vehicle maintenance regulations!

5. Replacing spark plugs and high voltage wires

Spark plugs in a car are the main parts for igniting the fuel mixture. With faulty spark plugs, there is an incorrect spark supply to ignite the gasoline mixture. Faulty plugs often have no spark or an incorrect spark interval, resulting in improper engine operation. If the spark plugs do not work properly during acceleration, especially from a standstill, you may feel slight jolts.

What are the reasons for the failure of spark plugs: Most spark plugs in pre-1996 vehicles need to be changed every 25,000-30,000 kilometers. In newer cars, spark plugs last more than 150,000 km. However, these scheduled spark plug replacement times may be reduced due to various factors related to fuel quality and driving style.

What needs to be done: If your candles have not been changed for a long time, or if you feel ignition-related failures in the engine, then you should immediately replace them with new ones without delay. Do not try to save money on late replacement of spark plugs, as the cost of candles is not very expensive, as well as the work of replacing them. By changing old spark plugs, you will improve engine performance and reduce vehicle fuel consumption. It is quite easy to change the spark plugs yourself. Basically, they are easily accessible under the hood of the car. You need an ordinary candle key to remove the spark plugs from the engine. It is also advisable to monitor the condition of the high-voltage wires, as over time they can become unusable and pass electricity that is transmitted to the spark plugs, which will reduce the strength of the spark. Remember that regularly changing your spark plugs, in accordance with your vehicle's maintenance schedule, keeps your exhaust catalyst from breaking down and improves engine performance!

All modifications Renault Sandero equipped with an on-board digital system capable of diagnosing errors and malfunctions in the operation of all units with integrated sensors. The first series of the car are equipped with electronic firmware code 6001, on later models with on-board computer firmware code 6002. As for the engine, fuel supply system, ABS, the malfunction indicator is located in the dashboard light panel in the instrument cluster. Decryption of the malfunction of a particular node in this case is not provided.

Diagnosis can be made in two ways: using the on-board self-diagnosis program or an external test device.

Entering diagnostic mode

The self-diagnosis mode is blocked by the program. Before checking, it is necessary to insert the key into the ignition lock. Activation of the diagnostic mode of any Renault Sandero model (except for the Prestige configuration, where it is permanently active) is performed by pressing the pin button on the dashboard. Without releasing the button, turn the key to the ignition on position (position "M"). Keep the button pressed for a few seconds until the numbers appear on the dashboard screen. After the information appears, the button should be released. In this case, while the test mode is active, the arrows of the speedometer and tachometer will make a constant movement from the zero position to the extreme points.

Information display

The information is displayed through four consecutive screen images. Changing images is done by a short press on the button.

Instrument testing

You can get more if you want. full information on the status of Renault Sandero systems. The fact is that the appearance of malfunctions is signaled by regular signal lamps on the dashboard. Data on what kind of breakdown takes place is not displayed on the scoreboard. In order to get a complete picture, you need to use a professional tester (adapter, scanner) or a special computer program that is compatible with the Windows package, which can be installed on a laptop. There are also dedicated apps for smartphones and tablets. The main thing is to choose the appropriate type of connecting cable.

As for the scanner, then, as a rule, a certain type of adapter is intended for each car model. Some testers transmit information directly to a computer via Bluetooth.

An external diagnostic device is connected to electronic system Renault Sandero through a 16-pin OBD-2 connector. It is located in the glove box of the front panel and is closed with a plastic plug.

During testing, the display of the device will not display information about the damage, but the so-called error code.
