Troubleshooting SID 51, FMI 4, Flash Code 31
Troubleshoot as follows:
NOTICE: |
|
To avoid damage to the harness and connectors when disconnecting harness connectors, ensure the pulling force is applied to the connectors and not to the wires extending from the connectors. |
- Check wire 561 (red, throttle power relay) for a short to ground at cavity S-3 in the Engine Sensor Harness (ESH) 30–pin connector (see Figure
"Engine Sensor Harness 30–pin Connector"
) and pin A in the 5-way digital output harness connector (see Figure
"Vehicle Interface Harness 5–way Connector"
). If there is a short, repair or replace the wire(s), pins, and sockets.

- If the code is still active, go to step 2.
- If the code is no longer active, refer to "6.4.2 Verification" .
- Check wire 562 (orange, fuel solenoid relay) for a short to ground at cavity T-3 in the ESH 30–pin connector (see Figure
"Engine Sensor Harness 30–pin Connector"
) and pin B in the 5-way digital output harness connector (see Figure
"Vehicle Interface Harness 5–way Connector"
). If there is a short, repair or replace the wire(s), pins, and sockets.
- If the code is still active, call Detroit Diesel Technical Service.
- If the code is no longer active, refer to "6.4.2 Verification" .
