April 30, 2020 Lada.Online 34,000 8

The fault indicator (Check Engine) on Lada 4×4 cars (VAZ 21214, 21314) is located in the instrument cluster. When the warning light turns on, it signals to the driver that the on-board diagnostic system has detected a malfunction of the ECM and the vehicle continues to move in emergency mode. To determine the cause, you should use a diagnostic tool, with which you can read error codes and decipher them according to the table below.

To carry out repair and maintenance work on the vehicle's engine management system, a diagnostic tool should be used. In service centers this can be a DST; for self-diagnosis, an ELM327 OBD-II scanner (price about 200 rubles, see the AliExpress catalog) and a smartphone with installed software (for example, OpenDiag), or an on-board computer installed in the car, are suitable for self-diagnosis.

VAZ error table

If replacing the fuel does not help, it is necessary to diagnose the air intake system. It is necessary to tighten the fastening clamps, change the air filter element and check the pressure in the rail (the normalized indicator is no more than 2.8 atm). It is also necessary to perform diagnostics:

Diagnostics of high-voltage wires is carried out using a tester; it is necessary to check the resistance. If the obtained value is more than 10 kOhm, then the cables must be replaced. You also need to check the integrity of the spark plugs and make sure that there is no carbon deposits on their tips. If the described actions did not help determine the cause, the cylinders are diagnosed. The user needs to check the compression level, which should be approximately the same in each device. If the obtained values ​​differ by more than 0.5 atm, then the power unit needs to be tested in more detail.

Chevrolet Niva error codes: decoding and description of meanings

The popular Russian-made model is very widespread in the CIS countries due to its optimal cost and increased cross-country ability, which is critically important in the conditions of domestic operation. Motorists buy cars for off-road travel and small towns, where the quality of roads leaves much to be desired.

The disadvantages of the car include weak wiring - when the load increases to the design limit, on-board electronic systems often fail, which causes software failures. Chevy Niva error codes appear on the dashboard display or are detected using special equipment, but the common thing is that they all indicate a malfunction of a specific component.

Lada 4×4 3d › logbook › the “check” light periodically lights up in the field 21214

Returning to the previous entry about the incomprehensible situation with the engine or brake pedal sensor... The burning “check engine” icon today, 08/20/2020, finally got to me and I decided to go for computer diagnostics of the car, check the Niva’s brains for possible errors. Previously, I drove around with my brother-in-law in his car those auto shops that I didn’t have time to visit in my Niva.

The new model brake pedal sensor I needed for the VAZ 21214 was not there either - all the sellers looked in amazement at the faulty sensor I was demonstrating, which I took with me, and unanimously turned their heads in different directions, saying the word “No”. Particularly advanced sellers, looking at the markings of the sensor, sent me to the foreign cars department, and my words that this sensor is being installed en masse on all domestic cars with an electronic gas pedal produced in 2021 were perceived with extreme distrust.

It seems like a sensor, like a sensor, if you believe the Internet, then it is produced by a plant in Arzamas, the sensor is marked 8200168238-B, on the other side there is an inscription in English “Renault 047”. On the official website in the city of Togliatti, its cost is set at 170 rubles. In Podolsk, they tried to sell me a sensor with the same marking, but made in Spain or France, for a minimum of 2200 and a maximum of 2900 rubles.

Everything is the same, only on expensive sensors there is additionally the inscription “Made in Spain” (the inscription is made in English). Having returned home, I got into my Niva and went to a car service center for diagnostics. My guess about the malfunction of the brake light switch off sensor or the simple “frog” turned out to be correct.

Having previously visited almost all the auto shops in my city in vain, I purchased the brake pedal sensor I needed at a car service center for just the negligible price of 350! rubles The “not original” sensor, completely black, made in France, is installed on some Renault cars. But then the most interesting thing began - the Niva’s engine worked intermittently, and continued to work.

The diagnostician constantly got errors “faulty injectors 1-2” and “misfire in cylinder 1.” During two hours of being in the service center, the spark plugs, the first and second injectors, spark plug wires, compression in all cylinders, and the ignition coil were checked for serviceability. I bought new ones with return conditions - an injector, an ignition coil, DENSO spark plugs (recommended at a car service center).

The spark plugs were original and they were black from carbon deposits. I must say that the electrician-diagnostician found it difficult to determine the malfunction of my car, because... The “misfire in cylinder 1” error appeared constantly, but periodically and disappeared when the engine was restarted. “DENSO” spark plugs were installed on my Niva, and the injector and ignition coil were returned to the seller.

Afterwards, the electrician went to “call a friend” in a nearby repair bay to get advice from other repairmen. In the next box there was a VAZ 2109 with similar symptoms, but with the error “misfire in the 3rd cylinder.” In total, I was told that my fault could not be detected (everything is normal) and they advised me to change the gas station where I constantly fill up my Niva .

I already own my third car, since 2006 I have refueled at only one, the only gas station in Podolsk, and I have never had problems with the engines of my cars. Although everything in our life always happens for the first time. At a car service center, I was advised to completely drain the gasoline from the gas tank and refuel at another gas station, drive around, look, and if the “CHECK” lights up again, then go for warranty repairs to the car dealership where I bought the car.

I just recently filled the tank full. Now there is 0.75 gasoline in the tank. I’m thinking about either pouring my gasoline into a canister, or driving around to produce gasoline, not paying attention to the burning “CHECK”... In terms of money: for two hours of work they charged me “divinely” 1,000 rubles, DENSO spark plugs 700 rubles, diagnostics with removal of the “CHECK” error 500 rubles. Total - 2200 rubles.

Chevrolet Niva error diagnosis

The most reliable way to identify what is wrong with a car is to diagnose electrical appliances and equipment. The procedure allows you to accurately identify breakdowns and quickly repair your car.

There are two ways to detect a problem in a car.

Self-diagnosis VAZ 2123

The simplest procedure allows the motorist to independently identify the damaged area and repair the damage. Thanks to the successful firmware of the on-board computer, some errors are displayed on the standard display. In this case, nothing happens on its own - you will need to perform several steps manually:

If the manipulations are correct, one of the indicated codes will appear on the display, and each Niva Chevrolet error number will be responsible for its own section of the highway:

At the same time, you need to accurately understand that, for example, when error 10 is on the display, the Chevrolet Niva tells the driver that there are several problems (standard, unambiguous codes are summed up).

You should also know that Niva Chevrolet self-diagnosis errors do not reflect the exact location of the breakdown. Codings can only show the section of the wiring where you need to look for the cause of the malfunction. Also, these encryptions may be the result of a software failure after an unsuccessful wash or disconnection of the battery. To obtain more accurate data, the user needs to connect a special diagnostic scanner.

Diagnostics using third-party equipment

More precisely, errors on Chevy Niva can be identified by connecting additional equipment. The technique is more technically complex, but allows us to determine the cause of a breakdown or failure with minimal error. In this case, the sequence of actions is as follows:

If all actions are performed correctly, all available information and any errors in the form of encrypted codes will be displayed in the desktop window.

There are also specialized scanners designed specifically for Chevrolet NIVA. Dealer devices are connected to the place of the standard signaling unit through an output cable.

Separately, we should highlight modern devices designed to connect a smartphone to a car, while reading encodings and controlling operating modes occurs directly from the gadget’s display.

At the same time, you should know what the encodings displayed during diagnostics mean. The code consists of several elements.

The next element is a single digit:

The following digit determines the exact serial number of the line in which the defect was detected:

Types of equipment used to check LADA

A list of diagnostic devices used not only in specialized car services, but independently, for example, in a garage. • Odometer correctors, with setting mileage values; • Models that support protocols, by reading information, erasing errors, codes are deciphered: ELM327 USB / Bluetooth / Wi-Fi running on the elm327 chip; • Vag adapter (cable) for later versions of the ECU and 12 pin pads; • Testers whose work is organized on the basis of oscilloscopes.

6.2.2. Self-diagnostic system (OBD) and codes

Warning

On models from 1990 to 1994, the obd1 self-diagnosis system is installed, and since 1995, the obd2 self-diagnosis system is installed.

To determine fault codes in the obd1 system, you simply need to disconnect the test connector located under the instrument panel. But to determine fault codes in the obd2 system, you need to use a special device to view fault codes. To diagnose the exhaust gas emission reduction system and control engine operation, it is advisable to use a digital voltmeter, which has a high input resistance and does not affect the operation of the circuit being tested (see Fig. Digital voltmeter ).

To determine fault codes and analyze engine control systems, it is necessary to use special scanners (see fig. Scanner ).

The ecm contains a built-in self-diagnosis system that detects and classifies faults in electrical circuits. When the ECM module detects a malfunction, the check engine light comes on, the malfunction is identified, and a fault code is recorded and stored in memory.

There are four methods for self-diagnosis of engine malfunction. The check engine warning light comes on if there is a fault in the u-mode.
