Possible malfunctions and methods for their elimination D-245E3
If a malfunction occurs during the operation of the vehicle (lighting up, flashing the diagnostic lamp of the “Common Rail” system), it is necessary to diagnose the “Common Rail” system using the diagnostic lamp and the diagnostic key and eliminate the identified malfunctions. The blinking of the diagnostic lamp characterizes the occurrence of a more serious malfunction than its continuous burning.
To diagnose, press the diagnostic key and hold it for more than 2 seconds.
After releasing the button, the diagnostic lamp will “flash” a three-digit engine fault blink code in the form of a series 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 of flashes (for example - three, mark the number - 3)
- - as a result, we have a fault blink code - "243" (Oil pressure sensor).
The next time you press the diagnostic key, the diagnostic lamp will “flash” the blink code of the next malfunction.
Thus, all faults recorded by the electronic unit are displayed.
After the last detected fault is output, the unit starts to output the first fault again.
For an explanation of fault blink codes, see the table D-245E3 fault codes.
Remove the fault in the manner indicated in the table and delete the fault record in the memory of the control unit as follows:
- - turn off the ignition and pause for one minute;
- - press the diagnostic key and, holding it, turn on the ignition;
- - hold down the diagnostic key for 5...7 seconds after turning on the ignition.
Perform a test drive to make sure the problem is corrected.
During this trip, the self-diagnosis checks the system and re-enters the memory of a possibly still existing malfunction.
After a test drive, re-read diagnostic fault blink codes from the memory of the control unit.
Now the error memory should be cleared, which means the repair was successfully completed.
If not all the malfunctions displayed by the control unit diagnostic system have been eliminated, then you need to proceed to the diagnostic post even if the malfunction that has occurred does not significantly affect the operation of the diesel engine, since the present malfunction can radically affect the deterioration of the environmental performance of the engine.
Not all malfunctions that occur can be recorded in the memory of the control unit. Therefore, while the diesel engine is running, watch the readings of the instruments, the color of the exhaust gases, listen to the work of the diesel engine.
When abnormal noises appear, stop the diesel engine, identify the cause of the malfunction and eliminate it.
If the problem persists, proceed to the service station diagnostics station.
Electronic information database of the service station provides support in further troubleshooting, gives instructions for troubleshooting.
