KamAZ error codes allow you to understand and most accurately determine the causes of malfunctions based on the vehicle’s passport data and correctly transmit this information, for example, in the same service. Any owner of such equipment will sooner or later need this information. Let's look at it in detail.
What does the error consist of?
The first character is a letter that determines the type of defective system:
- P – malfunction of the power unit or transmission (automatic transmission).
- B – malfunctions in the operation of body systems - airbags, electric windows, central locking, etc.;
- C – malfunctions in the chassis of the vehicle;
- U – errors associated with the interaction of electronic modules.
The second character is a number that determines the specificity of the malfunction:
- 0 – general symbol for OBD block;
- 1 and 2 – personal codes of the car manufacturer;
- 3 – reserved information.
The third character determines the type of failure:
- 1 and 2 – air or fuel supply;
- 3 – ignition unit, system for detecting misfires of the air-fuel mixture;
- 4 – additional emission control mechanism;
- 5 – control of vehicle speed and idle speed;
- 6 – electronic control modules, as well as their wiring;
- 7, 8 – errors in the operation of the gearbox;
- 9, 0 - reserve.
The fourth and fifth digits of the error are a number that corresponds to the serial number of the malfunction.
Possible malfunctions of the ignition system
The ignition system is checked if the starter turns and gasoline is supplied to the engine, but the engine cannot be started. Spark plugs and high-voltage wires are excluded from the list, since these units cannot break down at the same time. If KamAZ does not start, the reasons can only be determined through diagnostics.
Important! In the most difficult cases, the problem may be caused by a blown fuse, power failure, relay failure, contact damage, or engine ECU malfunction.
In this case, comprehensive diagnostics may be required, the results of which will determine the condition of the vehicle. You can also read about Wheel alignment on KamAZ - How to do it right.

Diagnostic specifics
The KamAZ engine can stall for various reasons, so you need to take into account the typical malfunctions for a specific car model. In some cases, clogs may occur due to low quality fuel, requiring professional cleaning.
In addition, each type of car requires special attention. For example, the battery of injection vehicles cannot be disconnected while the engine is running, you cannot perform actions with the batteries yourself, disconnect the ground on the car, or actively use charging and starting devices. When using diesel fuel, you need to remember that it is vulnerable to low air temperatures, as a result of which diesel sometimes freezes. The simplest are cars with gasoline engines, since they require a minimum of maintenance and are undemanding in terms of fuel and operating conditions.
KamAZ is also vulnerable to water, since its entry into the injector will lead to acidified contacts and breakdown of the technical system. To prevent unwanted problems, it is advisable to promptly change fuel filters and fill only high-quality fuel.
If KamAZ does not start, diagnostics are carried out taking into account the following aspects:
- is there fuel in the tank and is the fuel pump working;
- ignition system condition;
- Is the engine crankshaft timing sensor working?
- condition of injectors;
- technical condition of the ECU.
How to diagnose the error?
There are two ways to diagnose errors on KamAZ - using a computer, or using self-diagnosis.
Description of instructions for diagnosing a Bosch computer unit (Bosch) model MS 6.1:
- The car's ignition is turned on. Icons will appear on the KamAZ Kamens (Cummins) dashboard, including the Check Engine (ICE) fault indicator. The symbol will appear for three seconds and then disappear. If the indicator does not turn off, then there is a malfunction in the operation of one of the systems or components.
- Then you need to find a special diagnostic button; on most Kamins or Common Rail models,
it
steering
wheel on the center console. If this control element is missing, then you need to look for the key next to the safety module, opposite the passenger seat. - The button has two extreme positions and one fixed position in the center. The control must be lowered down or raised up and then held for two seconds.
- The button should automatically return to its original state after the driver releases it. Then the diagnostic indicator will begin to blink, first at longer intervals, and then at short intervals. The number of blinks indicates the first fault category, and the number of short flashes indicates the second. You need to write down all the errors, after which you will need to decipher them.
Diagnosis of KamAZ error codes using a computer and program is performed as follows:
- The scanner or laptop is connected to the vehicle control unit via the OBD2 connector.
- The diagnostic equipment is activated. Depending on the requirements specified in the service manual, the ignition is activated or the engine starts.
- Then you need to start reading errors on KamAZ Cummins or another model. The diagnostic scan tool or computer should show error codes on the panel. You need to find and find out what these codes mean in the list of errors; repairs are carried out in accordance with the received designations.

- Start the engine of a KamAZ Kamenz or other model and warm it up to operating temperature.
- Open the engine compartment of the car and disconnect the positive terminal from the battery. In this state, the battery should last about 5-15 minutes.
- The terminal is then connected back to the battery.
- The key turns in the ignition, but there is no need to start the engine. The lights on the dashboard will start blinking. In this position, the key is left in the lock for one minute.
- Then the ignition in the car is turned off.
Clutch adjustment
Adjusting the KamAZ clutch is carried out in several stages:
- Adjusting the free play of the clutch pedal. To do this, you need to measure the free play from the central part of the plate to the pedal itself. The gap should not exceed 12 mm. If the indicator is outside the normal range, you need to use an eccentric finger to press the pedal to the upper stop and turn the finger. Then you need to tighten the lock nut and measure the full stroke.
- Freewheel debugging. To do this, you need to move the fork shaft handle so that it moves in the direction of the spherical nut, which is located on the pneumatic power steering.
- Debugging the full stroke of the amplifier pusher. It is recommended to press the pedal all the way and measure the gap, which should be at least 2.5 cm. It is also necessary to measure the fuel fluid level in the cylinder block.
- Eliminate leaks in the system and adjust the clutch pedal sensor.
- Start the engine and check the operation of the coupling mechanism.

Tips for proper operation of KamAZ
KamAZ models 5350, 5490, 6520, 43118, 65115, 65201 deserve proper operation.
- It is recommended to use only suitable fuel. Often gasoline or diesel worsens the performance of a vehicle.
- A dirty air filter causes the KamAZ Euro 3 to take a long time to start. In this case, cleaning measures are carried out.
- Dirty fuel filter. In this case, the engine is also unable to produce power or start. Only maintenance will prevent such contamination.
- Mechanical engine failures. If the engine cannot be turned, evaluate the condition of the engine. If necessary, expensive repairs are carried out. The condition of the engine largely depends on proper driving.
- A malfunction of the fuel system will also lead to the fact that the KamAZ Euro 3 will not start and the vehicle cannot be fully used. The reasons are different, so they are determined by the exact circumstances that negatively affect the technical condition of the machine. For this reason, driving rules and using suitable fuel are mandatory.
In cases where the KamAZ Cummins 6isbe engine does not start and nothing can be done, the best option would be to turn to professionals, determine the cause and normalize the technical condition of the car. It is important to understand that there can be many reasons for breakdowns, and the degree of severity varies. Only professionals will determine the exact cause and condition of the units to carry out repairs and perform maintenance work.
The KamAZ manufacturer tries to make the car reliable, but there are situations when suddenly the KamAZ car stalls and does not start. This refers to the environmental class: Euro-3, Euro-4, Euro-5, Euro-6. At the same time, a message describing the error code appears on the instrument panel display. But there are exceptions when errors and the check do not light up. The described situation includes KAMAZ vehicles with the following engines:
- Cummins 6Isbe, 4Isbe
- Mercedes OM457La (KAMAZ-5490 NEO)
- 740 BOSCH MS6.1 (mechanical injection with electronic pedal)
- 740 EDC7 Common Rail (solenoid injectors)
