Car diagnostics
Diagnostics of the engine and other systems and units in Chevrolet Niva, Cobalt, Lacetti, Lanos, Captiva, Cruze, Aveo 2004, 2005, 2010, 2012 and other model years allows you to timely identify the fault. Thanks to this, the car owner can prevent more serious damage. The errors themselves when diagnosing with a laptop or on a VDO display or other factory dashboard will be different. In the first case, the car owner receives the most accurate information about breakdowns, which allows them to correctly decipher and remove faults. Error combinations will be four-digit.
During self-diagnosis on the on-board computer State on the instrument panel of a VAZ 2123 or Chevrolet Tahoe, Orlando, Blazer, Lanos, Niva, Lacetti, Cruz, Captiva, Epica, Aveo in the T250 and T300 body, faults are displayed in two-digit form. Instead of combinations, messages may appear on the display to warn motorists.
Pressing the odometer button on the dashboard
How to do it yourself?
There are two ways to check for errors in a Chevrolet: self-diagnosis or using additional equipment or a computer. In order for the on-board computer to test for faults, you need to hold down the button on the odometer to reset the daily mileage and turn the key in the ignition. This will cause the needles on the speedometer and gauges to start moving along the scales. And when you press the button again, the ECU will display a message on the display about the version of the firmware being used. After the next press, combinations of problems, if any, will appear on the screen.
What codes may appear on a Chevrolet Niva after self-diagnosis:
- 1 - the microprocessor is not working correctly;
- 2 — a break was detected in the electrical circuit of the fuel level controller in the tank;

How self-diagnosis of Niva Chevrolet is carried out and the main error codes
Not enough people understand that the Chevrolet Niva has a self-diagnosis function that produces the main error codes, which can be used to quickly find and fix problems with the car’s operation. It is not difficult to perform this function without the help of others; just press the odometer button firmly and turn on the ignition. The arrows on the speedometer will creep up, after pressing again, an information message about the firmware version will be displayed, and then all the error codes will appear on the monitor, of course, if there are malfunctions in the car.
Self-diagnosis
If there is no ability to check with a special device, then this can be done using self-diagnosis, which will help to quickly identify all problems associated with the operation of the vehicle. To do this, press the odometer button and turn on the ignition. The speedometer needle will begin to rise to the top, by pressing again the display will show information about the firmware, and by pressing again all existing errors will appear.
Let's take a closer look at the Chevrolet Niva error codes with decoding:
During self-diagnosis, error 8 and error 14 often appear. The first informs about problems in the braking system, and the second is related to fuel consumption, quite often this is a system glitch, but in any case it is necessary to change the sensor responsible for these mechanisms, or reset the memory by resetting the battery terminals.
As practice shows, knowing how to carry out an independent check is very useful, because this knowledge helps to quickly identify a malfunction and just in time to remove it.
Replacing oxygen concentration sensors
Oxygen sensors need to be replaced after 75 thousand km of vehicle mileage.
We unscrew the sensors when the engine has cooled down.
Disconnect the negative terminal of the battery.
To replace the control sensor, in the engine compartment, press the lock of the wire block and disconnect it
Disconnect the plastic holder of the sensor wiring harness from the bracket
Use a 22 key to unscrew the sensor.
We remove the sensor from the engine compartment
If the sensor is very stuck and cannot be unscrewed using an open-end wrench, then if you are replacing the sensor, you can cut the sensor wires with side cutters and unscrew them with a spanner.
You can also disassemble the wiring block if the sensor cannot be replaced.
To replace the diagnostic oxygen sensor, pry from the bottom of the car with a screwdriver and disconnect the wire holder from the protective casing of the wire blocks.
Using a 10mm wrench, unscrew the two nuts.
Remove the protective casing with wire blocks
We remove the wire blocks from the protective casing
We press the block clamp, disconnect the wiring harness blocks
Use a 22 key to unscrew the sensor.
Removing the diagnostic sensor
Oxygen concentration sensor
When installing the sensor, do not allow dirt and grease to get on the pads and the sensor itself.
We install the sensors in reverse order.
Check engine error
If a check light comes on on a Chevrolet Niva, this warns that there are malfunctions associated with the operation of the engine. The light comes on at the moment when the engine begins to detect a failure or error and writes a specific code into its memory.
Let's look at the main reasons for which this warning may appear:
- The air/fuel mixture is incorrect. This problem is eliminated by filling the tank with the highest quality gasoline.
- Low engine oil level
- Engine overheated
- There are problems in the ignition system, which may be due to a faulty spark plug or ignition coil
- The power system is faulty. It may be that fuel injection into one of the cylinders has ended.
- Lambda probe faulty
- A separate sensor in the ECM system has failed
We can come to the conclusion that in some cases, when the engine starts and the check light is on, this may indicate that the engine is running in emergency mode and the problem is not very critical. If the engine starts and stalls, then this is most likely a problem with the fuel supply or the crankshaft sensor has failed.
In any case, until you find out the exact cause of the drug, it is better not to use it.
Wiring diagram VAZ 2131 Niva injector
The Chevrolet Niva lambda probe, together with a sensor system, helps to properly regulate engine operation and use fuel extremely efficiently. This affects the amount of harmful emissions into the atmosphere.
On the Shnivy, the sensor is designed to transmit information to the computer regarding the amount of air coming out after combustion of the fuel. The information helps to adjust the composition of the fuel mixture and unlock the potential of the engine. It also significantly increases the life of the catalytic converter.
Chip tuning
Some drivers, in order to increase engine power, do chip tuning of the Chevrolet Niva. The essence of this procedure for us is to remove the established restrictions by adjusting good industrial options in the electrical control unit. This procedure helps to extract the additional performance inherent in the motor.
The whole process can be divided into several steps:
- Reading the required data from the electrical control unit
- Implementation of the necessary adjustment
- Update and record the latest data
The main advantage of this procedure is:
- Motor power increases
- Speed limit removed
- You can change the fuel type
- All factory options can be returned at any time
The disadvantages include:
- Highest cost of work
- The ECU may fail
- Increases fuel consumption, decreases system resource
- Errors may appear
Every specialist has a different attitude towards chip tuning, some consider it useful, while others believe that this procedure can have a bad effect on the performance of the car, while at the same time reducing its service life.
Summarizing the result, we can come to the conclusion that it is possible to identify error codes on a Niva Chevrolet either independently or with the help of a special device. If defects occur, they must be removed as soon as possible, otherwise this can lead to irreversible bad consequences in the operation of the entire system.

How to replace fuses on a VAZ 21213 (carburetor)?
The block is a metal board with flag-type disposable electrical fuses installed in it. A special fuse is provided for each electrical circuit and for all electrical appliances.
Fuse box
An electrical fuse is a low-melting wire core with two mounting legs enclosed in a plastic sheath. The shells are made of plastic of different colors. There is a marking on the top indicating the rating for which the fuse is designed.
In the event of a sudden surge in voltage, the thin wire instantly burns out and the circuit opens, thereby protecting the corresponding equipment from failure.
