COMMON RAIL system diagnostics: blink codes and fault table for the D-245.7E3 / D-245.9E3 engine

COMMON RAIL system diagnostics

If a fault occurs during the operation of the bus (the COMMON RAIL system diagnostic lamp illuminating or flashing), it is necessary to carry out diagnostics of the COMMON RAIL system using the diagnostic lamp and the diagnostic button and to rectify the faults detected.

Flashing of the diagnostic lamp indicates a more serious fault than intermittent illumination.

To carry out diagnostics, press the diagnostic button and hold it for more than 2 seconds.

After releasing the button, the diagnostic lamp will "flash" a three-digit blink code of the engine fault in the form of flashes.

This will appear as follows:

  • after releasing the diagnostic button — a pause, after the pause a series of flashes (for example, two — we note the digit 2);
  • a pause, after the pause a series of flashes (for example, four — we note the digit 4);
  • a pause, after the pause a series of flashes (for example, three — we note the digit 3);
  • as a result we have the blink code of the fault "243" (oil pressure sensor).

On the next press of the diagnostic button, the diagnostic lamp will "flash" the blink code of the next fault.

In this way, all faults recorded by the electronic control unit are output. After the last recorded fault has been output, the unit begins to output the first fault again.

See the decoding of the blink codes of faults in the table below.

Rectify the fault in the manner indicated in the table and delete the record of the fault in the memory of the control unit as follows:

  • switch off the ignition and maintain a pause for one minute;
  • press the diagnostic button and, while holding it, switch on the ignition;
  • hold the diagnostic button pressed for 5…7 seconds after switching on the ignition.

To make sure that the fault has been rectified, carry out a test drive.

During this drive, the self-diagnostics check the system and again record in the memory information about a fault that may still persist.

After the test drive, carry out a repeat diagnostic reading of the blink codes of faults from the memory of the control unit.

Now the fault memory should be cleared, which means the successful completion of the repair.

If not all the faults displayed by the control unit diagnostic system have been rectified, you must proceed to the diagnostic post even if the fault that has occurred does not significantly affect the operation of the diesel engine, since the fault present may fundamentally affect the deterioration of the engine's environmental performance.

Table of blink codes for diagnostics of the D-245.7E3 / D-245.9E3 engine

Note. Regarding the recognition of faults whose codes have been detected by the illumination of the diagnostic lamp, or were in the memory of the electronic control unit and whose codes have been detected by full system diagnostics, but are not reflected in the table below, it is necessary to contact a specialised service centre.

Not all faults that occur can be recorded in the memory of the control unit.

Therefore, during the operation of the diesel engine, monitor the readings of the instruments, the colour 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 fault and rectify it.

If the fault could not be rectified, proceed to the diagnostic post of the service station.

The electronic information of the service station database provides support in the further search for faults and gives instructions on fault finding.
