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.

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:

turn off the engine and turn off the ignition;
find the daily mileage reset button on the dashboard and press it;
at the same time turn the key in the starting cylinder;
if everything is done correctly, all the indicators on the dashboard will light up, and the instrument arrows will make a full circle and return to their place;
at the same time, the firmware version of the on-board computer will be reflected on the built-in display;
The next press of the key will display a network error.

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:

0 – error 0 Niva Chevrolet indicates that there are no problems in the on-board circuits; most likely, the breakdown is purely mechanical in nature;
1 – standard error of the Niva Chevrolet ECU – the processor is not working correctly;
2 – for a Chevrolet Niva, error 2 indicates a lack of power to the gas tank float;
4 – malfunction of the battery or generator; a critical excess of the rated voltage of more than 16 volts was detected in the on-board circuits;
8 – has the opposite meaning; on a Chevrolet Niva, error 8 indicates an excessive voltage drop in the wiring due to a deep discharge of the battery or a malfunction of the generator;
12 – error 12 Chevrolet Niva reports a breakdown of the control indicator;
13 – signal transmission from the lambda probe is disrupted, you need to check the device and main power lines;
14 – on Niva Chevrolet, error 14 indicates a critical antifreeze temperature, the system requires cooling, otherwise the power unit may boil;
15 – the motor is too cold for normal operation, usually the error disappears after a good warm-up or replacement of the sensor;
19 – malfunction of the DPKV, the encoding indicates an incorrect speed of rotation of the unit;
21/22 – the throttle position differs from the calculated values up/down;
23/25 – the air mixture on the intake manifold is excessively cooled or overheated;
24 – open circuit of the speedometer, accompanied by a lack of response of the instrument needle to the driver’s manipulations;
27/28 – incorrect display of the actual amount of exhaust from the calculated value;
33/34 – Mass air flow sensor, the indicators of the device are overestimated or underestimated, relative to the actual state of the system;
35 – incorrect operation of the engine at idle, you need to check the correctness of the mixture formation settings;
41 – the phase distribution sensor or DPRV has detected an open circuit or the data received is erroneous;
42 – multiple misfires were detected, the system turned off the fuel supply to the damaged cylinders;
43 – the detonation channel sensor generates an error;
44/45 – fuel mixture is too rich/lean; you need to check the fuel lines for mechanical damage;
49 – the vacuum gauge is out of order or overloaded;
51 – ROM has failed, or there is a breakdown in the power cables;
52 – RAM is not working correctly, damaged, no power;
53 – the adsorber purge valve is faulty;
54 – octane corrector controller is de-energized or broken;
55 – the calculated load on the internal combustion engine differs from the established one;
61 – the oxygen quantity controller in the intake system transmits incorrect data to the computer.

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.

How to decipher error codes on Chevrolet?

P The control unit receives incorrect data from the Chevrolet Niva processor error p0118 in the engine control module. Sometimes resetting the error and installing a so-called fake instead of a second oxygen controller helps. The catalyst device itself cannot be repaired; it can only be replaced with a new one. User A car enthusiast spoke about solving problems in the operation of the power unit in a Chevrolet car. Malfunctions of sensors Separately, we should consider problems with the Chevrolet Niva error p0118 controllers.

Error code Description and troubleshooting tips P, P, P, P, P, P One of these combinations reports problems that have arisen in the operation of the heating device of the oxygen controller or lambda probe.

More detailed diagnostics of the functioning of the sensor is required; there may be a problem with its connection. Therefore, it is also necessary to check the electrical circuit for an open or short circuit. Chevrolet Niva error p0118 The conductors are damaged, they must be replaced, the failed lambda probe P is being replaced, P The problem is related to the second oxygen sensor, in particular, it does not send a signal to the microprocessor module.

This leads to incorrect operation of the power unit as a whole, since the air-fuel mixture cannot form in the cylinders. The problem is caused by the regulator itself or problems in the power line.

Niva Chevrolet Error P0118 (High signal level TOZH)

A detailed diagnosis of the device and its plug is required; the oxidized contacts must be cleaned. If the wires are damaged, they are replaced or restored. P Malfunctions in the operation of the pressure control device in the manifold assembly. It is necessary to check the sensor and, if necessary, change it. P The absolute pressure controller is faulty. P Overload of the IAC control circuit. P Short circuit to ground in the Chevrolet Niva control circuit, error p0118 idle speed IAC.

P Chevrolet Niva error p0118 short to on-board power source or open circuit for controlling the idle air control regulator.

P Open circuit of the electric fuel pump relay control circuit. P There is no response from the car's anti-theft APS system or the circuit is open.

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:

turn off the engine;
find the contact connector under the dashboard, the connector is located at the bottom of the steering column;
connect the configured computer to the ECU output;
turn on the ignition;
follow the program instructions.

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.

Priora error codes and their interpretation

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.

First part:

P – the motor electronics have failed;
C – there are problems with the chassis;
B – interior space, a problem has been detected;
U – there are problems when establishing pairing of on-board systems.

The next element is a single digit:

0 – OBD 2;
1-2 – standard code of the manufacturer;
3 – reserve part of electrical equipment.

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

0 – exhaust system device;
1-2 – violation of the fuel or air supply device to the engine;
3 – ignition does not work correctly;
4 – additional equipment control;
5 – monitoring the engine idle state;
7-8 – transmission and chassis design.

Chip tuning

Some drivers perform chip tuning on their Chevrolet Niva to increase engine power. The essence of this procedure is to remove the established restrictions by adjusting the optimal factory settings in the electronic control unit. This procedure helps extract the extra performance inherent in the engine.

The whole process can be divided into several stages:

Reading data requested by the electronic control unit
Make the necessary changes
Updating and recording new data

The main advantage of this procedure:

Speed limit lifted
All factory settings can be restored at any time back
Increase engine power
You can change the fuel type

The disadvantages include:

The ECU may not work
Errors may appear
High labor costs
Increases fuel consumption, reduces system resources

Each specialist has his own attitude towards chip tuning, some consider it useful, and some argue that this procedure can negatively affect the characteristics of the car, while reducing its resources.

Decoding codes

Now we suggest that you familiarize yourself with the decoding of the combinations. Why errors may occur and how to eliminate them can only be found out as a result of diagnostics.

The elm327 channel published a video showing the diagnostic procedure for a Chevrolet Niva using a special adapter and an Android-based mobile phone.

Common mistakes

First, let's look at deciphering frequently occurring problems that occur in the Chevrolet Aveo in the back of the T250, T300, Niva and other models.

Error	Decoding
p1396	Code p1396 is an error in the operation of the ABS system. If this code appears in an Orlando, Niva, Lacetti or other Chevrolet model, the car owner needs to test the performance of the unit itself, as well as the rough road controller. Often the cause of 1396 is a failed sensor, damage, oxidation or contamination of its contacts. You can try to solve the problem by dismantling and cleaning the connector
p0661	The car owner is informed about problems with the solenoid or damage to the electrical circuit. A detailed check needs to be done
p0404	The on-board computer received a message about violations in the functioning of the exhaust gas recirculation system. Often the reason is related to a breakdown of the controller, so it is necessary to diagnose and replace the sensor
p1628	Error code 1628 indicates a problem with the locking device. It is necessary to test the operation of the immobilizer. If you do not pay attention to diagnosing and checking this error, then over time the immobilizer may block the engine and, as a result, it will be impossible to start it. You can try to disable and activate the immobilizer or reprogram its chip
p1661	The Check Engine light does not work. You need to check the functionality of the indicator light in the dashboard. Often the problem can be solved if the light bulb is working by resetting the error
p1602	Error 1602 literally means a loss of voltage in the on-board network. The reasons may be different. If the car starts and the engine runs normally, the malfunction may be damage or poor contact of one of the plugs of the control unit, or poor soldering of its components. Perhaps this is a firmware glitch or some relay is not working. A qualified electrician can find the cause.
136	The meaning of this code may vary for different Chevrolet models. In Orlando cars, this error means a malfunction of the second lambda probe or damage to the wiring. In Cruze models, the code indicates the need to diagnose the parking radar. Perhaps the parking sensors are simply clogged

The My Altai channel published a video in which the author talked about diagnosing a Chevrolet Niva car using a Bluetooth adapter and an OBD-2 connector.

Chevrolet Niva error reset

The standard procedure for resetting the controller occurs only after all faults have been completely corrected, otherwise annoying encryption will appear again. The procedure is performed in two available ways.

Disconnect the battery from the on-board network for 10-15 minutes. The controller will completely reboot and return to factory default settings.
In the BC menu, enter the “errors” service, press the daily mileage reset button and wait for the sound signal from the car, and horizontal lines should appear on the display.

SELF-DIAGNOSTICS OF THE KALINA/PRIORA INSTRUMENT COMBINATION

With the ignition off, press the “Reset” button (reset daily mileage). While holding the button, turn on the ignition.
The instrument cluster will go into self-diagnosis mode, all segment positions will light up on the display, all indicators will light up, and the arrows will travel the full path.
Use the control button on the right steering column switch to switch between modes (self-diagnosis, firmware version, error codes).
To reset errors, you must be in error mode and press and hold the “Reset” button for more than 3 s.
The diagnostic mode exits automatically after 20-30 seconds of inactivity.

Decoding error codes in the dashboard:

5-external temperature sensor error (if there is no sensor reading within 20 seconds, the LCD displays “-C”);
E-detection of an error in a data packet built into the EEPROM.
2-increasing the voltage of the on-board network;
3-fuel level sensor error (if an open circuit in the sensor is detected within 20 seconds);
4-error of the coolant temperature sensor (if an open circuit of the sensor is detected within 20 seconds);

8-malfunction of the brake system (the criterion for turning on the sound signal is met);
7-emergency oil pressure (the criterion for sound alarm activation is met);
6-engine overheating (buzzer activation criterion met);

Bottom line

The most common Niva Chevrolet computer errors are found in 90% of car diagnostic cases. There are also a large number of rare failures that are not included in the list due to their low prevalence.

01 April 2022 20 316

The fault indicator (Check Engine) on Chevrolet Niva cars 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.

Auto parts for foreign cars, auto repair

P The control unit has detected a mechanical fault in the idle air boost drive. P The ignition off timer in the engine management system has failed.

Decoding the P combination As mentioned above, the P code is a common combination when diagnosing a Chevrolet car. P indicates that incorrect data is being received into the control unit from the ABS control unit.

In particular, when R appears, the BC signals a malfunction of the bad road sensor.

Chevrolet Niva error codes. Carrying out diagnostics.

This time there is nothing to worry about, as the appearance of such messages may be due to a lack of communication with the device itself. It is also worth checking the standard chevrolet niva error p0118 anti-theft system, if so, then check the adapter itself. As standard, it is connected to the diagnostic line between the ECU and the immobilizer.

And if it is missing, a plug is installed in its place. To restore communication with Chevrolet Niva error p0118, install a jumper with contacts, as shown in the following figure: Depending on the year of manufacture, the connectors may differ from each other. Self-diagnosis. If it is not possible 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 car.

The speedometer needle will begin to move up, when pressed again, information about the firmware will appear on the screen, and when pressed again, all existing errors will be shown. Let's take a closer look at the Chevrolet Niva fault codes with their decoding - as practice shows, knowing how to carry out an independent check is very useful, since this knowledge helps to quickly identify the fault and fix it in a timely manner.

Check engine error If a check mark is lit on a Chevrolet Niva, this warns of the presence of malfunctions associated with Chevrolet Niva error p0118 with engine operation.

Chevrolet Niva error p0118 occurs at the moment when the engine begins to correct a malfunction or error and writes a certain code into its memory. P, P valve of the exhaust gas recirculation system is faulty or blocked - the device requires replacement.

P The on-board computer has detected a controller malfunction - the device needs to be reprogrammed. P The control unit reports a malfunction of the engine control system controller.

Check Engine

When the ignition is turned on, the indicator should light up, so the ECM checks the serviceability of the lamp and control circuit. After starting the engine, the indicator should go out if the controller memory does not contain the conditions for turning it on.

If:

The Check Engine light is constantly on - in this case, the driver is obliged to make the vehicle available to service technicians as soon as possible.
A flashing Check Engine Light indicates a problem that can cause serious damage to the ECM (for example, a misfire can damage the catalytic converter).

To protect against random, short-term errors that may be caused by loss of contact in electrical connectors or unstable engine operation, the warning light turns on after a certain period of time after detecting a malfunction in the ECM. During this period, the on-board diagnostic system checks for a malfunction.

After eliminating the causes of the malfunction, the alarm will turn off after a certain delay time, during which the malfunction does not appear, and provided that there are no other fault codes in the controller’s memory that require turning on the alarm.

When clearing (deleting) fault codes from the controller’s memory using diagnostic equipment, the indicator goes off.

Chevrolet Niva error 8 how to fix

Disassembling the panel

If the shield malfunctions, it will have to be disassembled in any case to determine the cause of the breakdown. How to remove the instrument panel? “Niva-Chevrolet” will not cause problems in this sense.

This is done as follows:

Use a slotted screwdriver to pry up and remove two plugs. The first is located to the right of the hazard warning button, and the second is in the far right corner of the panel trim.
We turn out the screws located under the plugs.
We pull out the right side of the dashboard trim and remove the connectors from the control buttons. Remember (take a photo) which connectors go to which buttons!
We disengage the left side of the trim, remove the block from the buttons for turning on the headlights and dimensions. We remove and remove the lining.
Unscrew the two screws securing the dashboard. Disconnect the connectors.
We remove the panel.

Self-diagnosis

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 DST 2M (DST-10, DST-12), for self-diagnosis an OBD-II scanner ELM327 (price about 200 rubles, see the AliExpress catalog) and a smartphone with installed software (for example, OpenDiag) are suitable. or an on-board computer installed in the car.

Error P2188

P2188 (Fuel supply system rich at idle) is one of the most common errors on the Chevrolet Niva.

Code P2188 is entered if:

the engine is idling;
fuel supply control is carried out in feedback mode based on the signal from the control oxygen sensor (B_LR = “Yes”);
the fuel supply adaptation function is activated (B_LRA = “Yes”);
the value of the RKAT parameter is outside the lower limit of the acceptable range (-8%).

The Check Engine light comes on after 2 drive cycles in which the check was unsuccessful.

Use the following flowchart to determine the cause of the problem:

After repair, start the engine, reset the codes and make sure there is no malfunction.

ELM327 Niva, specifics

Bluetooth adapters ELM327

When I became concerned about this problem, I attracted an electronics engineer friend of mine, who is very, very meticulous in his profession. He immediately told me the following phrase: China and China are different. I have already tried to convey this idea to the people in an article about rear brake pads. On the current issue, we ordered several samples directly from the FACTORIES and began to slowly mock them, open them and break them. I won't wait long. Only ONE adapter connected normally with the fields and shnives. In the photo, he is in the middle. The rest either did not communicate with the smartphone or did not connect to power at all. Even my branded Konnwey adapter (far right), which sees almost the entire Japanese fleet and half of Europe, did not want to communicate with the fields.

Attention. The main and main function of this Bluetooth adapter ELM327 Niva is only one - to view and erase errors and turn off the “check engine on the panel” light. You can't do anything else on a wireless device. If you want to make friends with the engine more seriously, the tool must be different. A wired USB adapter (possibly with the same ELM327 chip) and a laptop with more serious diagnostic programs.

Computer diagnostics of the Chevrolet Niva family of cars is carried out to determine fault codes (error codes), as well as to obtain its decoding for further repairs.

Error P1602

P1602 (Court Controller, power supply loss) is another common Chevrolet Niva error.

Code P1602 is entered if the following conditions are met:

ignition on;
The controller has detected a loss of RAM data.

The codes should be cleared using a scan tool. If the code is entered again, check the power supply circuit from the battery to pin “12” of the controller.

Realities

Let's look at the ELM adapter from a purely technical perspective. Its function is simple - it is a translator between the car's ECU and your smartphone or tablet. But translators are different, I declare this responsibly, as a person who speaks German. There are general translators, there is a technical language, there is a diplomatic language, and there is the pinnacle of the art of translation - simultaneous translation. The Chinese wireless version of the ELM adapter represents a high school student who got a C in English and thinks that he knows the language. It would be appropriate to recall an anecdote on this topic. *The Georgian went swimming and began to drown. I either didn’t know the word “help” or forgot it. A man is walking along the shore. The Georgian shouts: uh, darling, help, I’m swimming for the last time. * This is approximately the same information provided by the vast majority of Chinese “Elms”. The Chinese are deceiving consumers twice. First point: a real original ELM 327 chip costs about $20. This doesn't look like 400 rubles. The second point is that all electronics that end up on Ali and other similar sites are shamelessly cut down to cost 400 rubles, or even better, 300, or even better, even cheaper.

How to run diagnostics?

Press the daily mileage reset button and hold it. Turn on the ignition and release the button.

The arrows on the dashboard start moving - this is the entry into the mode. Press the button briefly twice and it will display an error code.

As follows:

Nothing is clear, but there is a special table that deciphers these codes. It looks like this.

Sometimes it happens that the code we need is not in the table. This is fine. If the figure is not the same as in the table, then this means the presence of two malfunctions at the same time. For example, code 6 means the simultaneous presence of codes 2 and 4. And code 10 means errors 2 and 8.

All other error codes are deciphered in the same way. True, this system is quite primitive. Normal diagnostic tools have more detailed information about faults. The codes would look, for example, like this:

“P0303” - 03 means misfire, and the second 03 is the cylinder number. That is, the engine is tripping.

Error codes on the dashboard provide little information. It is much better to use special diagnostic equipment. Even the cheapest one can scan almost all Chevrolet Niva engine errors.

It may happen that an unknown combination of numbers and symbols appears on the dashboard, this indicates that the on-board computer is warning you that there are certain malfunctions in the car, and in order to correctly decipher the error codes on the Niva Chevrolet car and make the necessary repairs, you need to know what this or that information warns about. This article will help you with this, as in it we will look in detail at what different combinations of numbers mean and how to correct them.

But before we look at what errors there may be, let’s figure out how to detect and decipher them in general. In order to do this, you must first of all diagnose the car itself, since you can’t do without it. One of the simplest diagnostic methods is the information that appears on the dashboard, but in addition to numbers, certain phrases can also be displayed, but the car owner cannot always understand the translation of this message.

To find out in more detail about the causes of a breakdown on a Niva Chevrolet car, you can use a special scanner. It is a laptop computer with special software installed, thanks to which self-diagnosis occurs without any problems.

Scanner types:

Universal ones, which are usually used by many specialized car services, but they cannot be called full-fledged since they do not always allow one to identify certain errors.
The second type of scanners is dealer scanners. They are not sold in the public domain; they can only be purchased from an official dealer. This device detects breaks associated with electrical wiring without any problems; it can be used to interrogate the on-board computer and chip key. Having this device, you can easily determine what errors they are talking about.

Now let's take a closer look at what errors can appear in the Chevrolet Niva SUV and what they mean.

Dashboard faults

The instrument panel, like any other electronic component, is susceptible to harmful factors such as a short circuit, broken wires in the power or information circuit, or a malfunction of one of the main components of the device. If you have encountered a similar problem, first of all, determine what signs of failure the shield is showing:

the panel does not function at all, but the engine starts and runs normally;
The Niva-Chevrolet instrument panel does not light up, but all indicators work (no backlight);
The speedometer and tachometer do not work;
Temperature and fuel level sensors are not functioning.

In the first case, contact on the device connectors is most likely lost. It is enough to disconnect the pads, clean the contacts, and everything will work again. A similar malfunction can overtake you in the fall or winter, when the level of moisture in the air is high.

If on a Niva-Chevrolet car the instrument panel lamps do not light up, but all its elements are operating normally, the reason must be sought in the power wires of the lighting bulbs, or in the lamps themselves.

Failure of the tachometer or speedometer also indicates a break in the power circuit. The same can be said if there are problems with the fuel level and temperature sensors.

How is self-diagnosis performed?

Most car enthusiasts prefer to regularly go for computer diagnostics of their vehicles. If you do not have the opportunity to visit a service center or do not have a scanner to check the car, then you can do it differently - run the on-board computer diagnostic program. To do this you need to do the following:

Press the daily mileage reset button on the odometer and at the same time turn the key in the ignition.
If you did everything correctly, the speedometer and gauge needles will begin to move along the scales.
Click the reset button again. The display will show the current firmware version of the on-board computer. After this, you need to repeat the action with the reset button so that the bookmaker displays whether there are errors in the system. If they are present, their numbers will be shown on the display.

This diagnostic will not take much of your time; you can quickly check the Chevrolet Niva system. If the number 8 appears on the display, then do not be upset - this error with number 8 is not terrible in most cases, you just need to check individual components of the car.

How to find out the ECU version

If you don’t know what ECU you have, there is, of course, the option of removing the glove compartment and reading the markings.

No similar programs appeared on the iPhone? My whole family has apples, I’ll have to take one of my friends to the garage

I have never done such a diagnosis on my VAZ, although I have had it for more than five years. With such an adapter and program, there is no need to go to the station.

I have a modern smartphone based on Android, so downloading the OpenDiag program and diagnosing the car should not be a problem.

What does error 8 mean?

In the table for decoding error codes of the on-board computer, error number 8 means that there is low voltage in the electrical network of your Chevrolet. To eliminate it you need to do the following:

check the battery charge status;
diagnose and, if necessary, repair the generator.

Most often, error 8 appears due to problems with the battery. It may lose its capacity over time and produce a voltage less than 8 V required for the normal functioning of the electrical network and vehicle sensors. Similar procedures are carried out if the network voltage is too high.

If you think that the error message was not generated by the on-board computer due to a problem, then you can check its readings. To do this, remove the negative terminal from the battery for 10 minutes, and then plug it back into the power supply. If there are no problems, then the error on the dashboard will disappear.

Tuning options

The choice of options for tuning is not particularly large:

Install a device from another car. In this case, you will need the services of a qualified electrician, since the connectors will have to be redone. You can also install a digital version of the tidy - it will be more than original.
As a tuning option, you can install LED bulbs instead of regular ones. Many car owners choose this option because it is less expensive and the easiest to implement.
Another tuning method is to install original instrument scales on the speedometer, tachometer and other sensors. Moreover, you can buy such scales either ready-made or make them yourself in accordance with your preferences.

What problems may be hidden in the Chevrolet Niva generator

If you are sure that the battery is in good condition and produces sufficient voltage, then you need to diagnose the generator. It is one of the weak points of the Chevrolet Niva. During its diagnostic process, malfunctions may be detected:

pulley wear or damage;
wear of current collecting brushes;
rectifier failure;
failure of the voltage regulator;
destruction or wear of the bearing;
wires are damaged;
collector wear.

Before dismantling, you can check the generator by paying attention to the headlights and other signs. The malfunction is present in the following situations:

headlights burn dimmer than usual;
while the engine is running, the battery discharge lamp lights up or flashes on the dashboard;
as engine speed increases, the brightness of the headlights changes;
spontaneous shutdown of the radio;
rapid battery drain.

If you have these problems, you need to replace the generator or its parts. We will give examples of how to install new brushes on this unit or replace it entirely.

Design Features

What can the instrument panel tell us? The Chevrolet Niva is designed in such a way that its panel unites all the control devices of the car. It includes:

speedometer;
odometer (counter of kilometers traveled);
tachometer (crankshaft revolution counter);
coolant and ambient temperature indicators;
fuel level indicator;
12 control (signal) lamps.

In order for the driver to monitor instrument readings at night, the panel is illuminated when the side lights are turned on. How bright is the instrument panel backlight? "Chevrolet Niva" has the function of adjusting the level of illumination of the dashboard. It is provided by six special light bulbs.

Important: the shield has an electronic design and cannot be repaired if it fails! Spare parts in the form of individual panel units are not available for sale. The only exceptions are signal and lighting lamps. In other words, if at least one indicator fails, you will have to buy an assembled panel.

Replacing brushes or the generator itself

Current collection brushes wear out most often, so here is a description of how to do this job:

Remove the negative terminal from the battery and disconnect the wires leading from the generator casing.
Remove the protective cap from the terminals of the positive terminal of the wires. Unscrew the nut that secures the block to the generator block.
Disconnect the spring clips and remove the black plastic cover.
Unscrew the voltage regulator mountings with a Phillips screwdriver. Take it out along with the brushes.
Disconnect the wires from it. Remove the assembly together with the fastening bar, take off the belt.
Release the generator from the bracket by unscrewing all the mounting bolts.

The further plan of action depends on what you will change. If the brushes are very worn, they need to be replaced. If the current collectors are visually intact, then the reason may be in other parts of the generator. In most cases, car enthusiasts simply change it entirely.

Why is error 8 associated with brake system problems?

Some car enthusiasts misinterpret error message 8, believing that they need to check the brake system. This is due to the fact that on VAZ cars this fault number indicates insufficient brake fluid level.

The Chevrolet Niva's on-board computer uses different designations, so you should not interpret them in the same way as in the VAZ. If you doubt the condition of the brake system, you can check it during the repair process. First of all, pay attention to the brake fluid level, and then check the pads.
