Test Step 1. Inspect Electrical Connectors
and Wiring
A. Inspect the following connectors:
•
P1 connector
•
P2 connector
B. Inspect the terminal connections on the glow
plug start aid relay. Refer to Troubleshooting,
"Electrical Connectors - Inspect" for details.
C. Perform a 45 N (10 lb) pull test on each of the
wires in the ECM connector that are associated
with the glow plug starting aid.
D. Check the screw for the ECM connector for the
correct torque of 5.0 N·m (44 lb in).
E. Check the harness for abrasion and pinch points
from the glow plugs back to the ECM.
F. Check that the fuses are not blown.
Expected Result:
All connectors, pins and sockets are correctly coupled
and/or inserted. The harness is free of corrosion,
abrasion and pinch points. The fuses are not blown.
Results:
•
OK – The harness and the connectors appear to
be OK. Proceed to Test Step 2.

connectors.
Repair: Repair the connectors or the harness
and/or replace the connectors or the harness.
Ensure that all of the seals are correctly in place
and ensure that the connectors are completely
coupled. Replace blown fuses.
Verify that the repair has eliminated the fault.
STOP.
Test Step 2. Check for Active Diagnostic
Codes
A. Connect the electronic service tool to the
diagnostic connector.
B. Turn the keyswitch to the ON position.
Note: Do not start the engine.
C. Use the electronic service tool to select the "Glow
Plug Override Test" in order to turn on the power
for the glow plugs.
D. Check for active diagnostic codes or recently
logged diagnostic codes.
Expected Result:
The following diagnostic code is active or recently
logged:
•
