If a malfunction occurs during operation of the bus (the diagnostic lamp of the "COMMON RAIL" system lights up or flashes), it is necessary to diagnose the "COMMON RAIL" system using the diagnostic lamp and diagnostic key and eliminate the identified malfunctions
Flashing of the diagnostic lamp indicates the occurrence of a more serious malfunction than intermittent lighting.
To diagnose, press the diagnostic key and hold it for more than 2 seconds.
After releasing the key, the diagnostic lamp will “blink” the three-digit blink code of the engine malfunction in the form of flashes. It will look like this:
- after releasing the diagnostic key - pause, after a pause a series of flashes (for example - two, mark the number - 2), - pause, after a pause a series of flashes (for example - four, mark the number - 4), - pause, after a pause a series flashes (for example - three, mark the number - 3) - as a result, we have the fault code blink code “243” (Oil pressure sensor).
The next time you press the diagnostic key, the diagnostic lamp will “blink” the blink code of the next fault.
Thus, all faults recorded by the electronic unit are displayed; after outputting the last detected fault, the unit begins to display the first fault again.
Deciphering the blink codes of faults, see the table below.
Remedy the fault in the manner indicated in the table and delete the fault record in the control unit memory as follows:
- - turn off the ignition and pause for one minute;
- - press the diagnostic key and, holding it, turn on the ignition;
- - hold the diagnostic key pressed for 5...7 seconds after turning on the ignition
To make sure the problem has been resolved, take a test drive. During this trip, the self-diagnosis checks the system and again stores information about a possible remaining fault
After a test drive, re-read the diagnostic fault codes from the control unit memory.
The error memory should now be cleared, indicating successful completion of the repair
If not all the faults displayed by the diagnostic system of the control unit have been eliminated, you need to proceed to the diagnostic station even if the fault that has arisen does not significantly affect the operation of the diesel engine, since the present fault can radically affect the deterioration of the environmental performance of the engine.
Engine diagnostic blink code table
Note: Regarding the recognition of faults, the codes of which were detected by the lighting of the diagnostic lamp, or were in the memory of the electronic control unit and their codes were identified by a complete system diagnosis, but are not reflected in the table below, you must contact a specialized service center.

Not all faults that occur can be recorded in the memory of the control unit.
Therefore, while the diesel engine is running, monitor the instrument readings, the color of the exhaust gases, and listen to the operation of the diesel engine.
If abnormal noises appear, stop the diesel engine, identify the cause of the malfunction and eliminate it.
If the fault cannot be resolved, proceed to the service station diagnostics station.
Electronic information from the service station database supports further troubleshooting and provides instructions for troubleshooting.
