Schematic for the fuel injection pump and the ECM power supply
A. Turn the Keyswitch to the OFF position.
B. Disconnect the P40 connector from the fuel
injection pump.
C. Turn the keyswitch to the ON position.
D. Measure the voltage between P40:7 + Pump
Supply and P40:6 - Pump Supply.
Expected Result:
The measured voltage is between 11.0 VDC and 13.5
VDC for a 12 volt system and between 22.0 VDC and
27.0 VDC for a 24 volt system with no suspected
intermittent problems at this time.
Results:
•
OK
Repair: The wiring harness and the voltage
supply to the fuel injection pump are correct. The
problem is in the fuel injection pump or there is a
communication problem between the ECM and
the fuel injection pump. Refer to Troubleshooting,
"CAN Data Link Circuit - Test". If the CAN Data
Link is correct the problem is in the fuel injection
pump. Contact the Perkins Technical Support
Centre in order to check if the software version
is correct. Also check that there have been no
software updates. If the problem still exists contact
the Perkins Technical Support Centre in order to
change the fuel injection pump. The warranty of
the fuel injection pump will be affected if the pump
is replaced without prior consultation. Replace the
fuel injection pump. Refer to Disassembly and
Assembly, "Fuel Injection Pump Remove and
Install". Check for active diagnostic codes.
STOP.
