Error codes for VAZ 2110 and VAZ 2112 with interpretation

On Lada cars produced in 2001 - 2007 and subsequent ones, the manufacturer installs a BC capable of performing a self-diagnosis procedure. Thanks to this, the motorist can independently read the fault codes of the VAZ 2112 and determine the presence of a breakdown. Errors are reflected on the instrument display in the form of one or two-digit codes. The disadvantage of the procedure is the lack of an accurate determination of the location of the breakdown - self-diagnosis is only capable of a general determination of the circuit. Faults can also be read using additional equipment. The connected scanner provides detailed information about the specific location of the breakdown.

Error Diagnosis Methods

In 2022, errors on the VAZ 2110 on-board computer can be identified in two ways.

Self-diagnosis. The method is feasible thanks to a special option in the on-board computer. The principle is that the system shows faults in the main circuits and mechanisms. The advantage is that there is no need for additional equipment or special programs - everything that is needed is already “hardwired” into the on-board computer. The disadvantages include the low accuracy of the readings.
With the help of auxiliary equipment. This type of procedure is characterized by high accuracy of the read data. Thanks to a third-party analyzer, you can find out exactly where the breakdown occurred, which simplifies the repair process. An obvious disadvantage is the need to connect a computer with a special program. Such equipment is present only in specialized service stations.

Self-diagnosis VAZ 2110: error codes

To enable self-diagnosis mode, the driver or technician will need to perform a certain sequence of actions.

Turn off the engine ignition.
Press the daily mileage reset button and, without releasing it, turn on the ignition. In this case, all digital cells should light up on the display.
Click on any module control button twice.
The device will display the error number.

If everything is done correctly, one of the following symbols will light up on the device:

2 – critical excess of the rated voltage of the on-board network, a short circuit of the main line or loaded components is possible;
3 – a similar error on the instrument panel of the VAZ 2110 indicates that the gasoline level sensor is damaged or there are problems in the sensor’s power supply; to check, you can replace the part with a new one and ring the circuit;
4 - error 4 VAZ 2110 indicates that the antifreeze temperature sensor is broken or its wiring is broken, the problem is resolved in the same way;
5 – the thermometer designed to measure the temperature outside is faulty;
6 – the engine is very overheated, you need to stop and wait for it to cool down, and there should be a sound signal (add antifreeze/water into the radiator);
7 – the lubricant pressure in the crankcase compartment of the engine is below the established norm, the losses must be urgently replenished;
8 – error 8 VAZ 2110, interpretation shows that the brake system is damaged, possibly a drop in the fluid level in the expansion tank or severe wear of the pads;
9 – the battery is completely discharged, the element needs to be charged or replaced with a new module;
E – software failure of the on-board computer firmware; complete diagnostics with a scanner and qualified repairs in a workshop will help here.

Also, error 14 VAZ 2110 or another two-digit number will indicate the presence of two problems. Usually, with such a picture, the ciphers are summed up. For example, error 10 VAZ 2110 may indicate problems in circuits No. 4 and 6.

How to reset errors on a VAZ 2110

Typically, the procedure is carried out after repairing the unit for which the fault code is responsible. In this case, the symbol does not disappear - it must be forcibly reset. This is done quite simply. The user is required to enter the service mode (hold down the daily mileage button), then double-click on any control. After completing the manipulations, a code will appear on the display. To eliminate this, the daily mileage button is pressed for 3-4 seconds and the system is reset. The machine exits the dialog box automatically after 30 seconds of inactivity.

B – body systems are damaged;
C – a problem has been detected in the vehicle’s chassis;
U – violation of pairing of different modules.

First digit:

0 – general value;
1/2 – manufacturer code;
3 – reserve.

Second digit:

1-2 – violation in the air-fuel mixture supply devices;
3 – malfunction of the ignition units;
4 – atmospheric emissions control device;
5 – malfunction of the engine speed or engine speed meters;
6 – failures in electronics;
7-8 – malfunction of the gearbox module;

Some suggested steps to troubleshoot and fix error code P0261:

Read all stored data and error codes using an OBD-II scanner.
Clear error codes from your computer's memory.

Symptoms of malfunction

The main driver symptom of P0261 is the MIL (Malfunction Indicator Light). It is also called Check engine or simply “check light”.

They can also appear as:

The “Check engine” warning light on the control panel will light up (the code will be stored in the ECM memory as a malfunction).
Floating speed, the car engine may operate unstably.
Increased fuel consumption.
The engine stalls or has trouble starting.
Jerking/misfire at idle or under load.
Poor speed gain.
Black smoke from the exhaust pipe.

P0261 is above average in severity and should be used with caution. Because the vehicle may experience serious problems, potentially affecting safety.

Prevention of breakdowns of electrical appliances

To prevent breakdowns of electrical circuits, you must follow a number of simple rules.

Periodically check the contact connectors for oxidation or overheating. Rust disrupts the passage of impulses, which can be read by instruments as damage to the unit.
Once a year, treat contacts with special oils. Lubricants prevent moisture from entering metals, which prolongs their service life.
Replace dry wires in a timely manner. Cracked insulation can cause a short circuit.
