Inspect the following connectors:
P1 connector
P2 connector
Inspect the terminal connections on the glow plug start aid relay. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
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.
Check the screw for the ECM connector for the correct torque of 5.0 N m (44 lb in).
Check the harness for abrasion and pinch points from the glow plugs back to the ECM.
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.
Not OK - There is a fault with the harness and 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 coupled correctly. Replace blown fuses.Use the electronic
