1. Inspect Electrical Connectors and Wiring
A. Thoroughly inspect the terminal connections on the P1 ECM connector and the switch connector.
Refer to Troubleshooting, "Electrical Connector - Inspect".
B. Perform a 45 N (10 lb) pull test on each ground level shutdown wire in the ECM connector and the switch connector.
C. Check the screw for the ECM connector for the correct torque of 5 N m (44 lb in).
D. Check the harness for corrosion, abrasion, and pinch points from the solenoids to the ECM.
Loose connection or damaged wire
Result: There is a fault in a connector or the wiring.
Repair: Repair any faulty connectors or replace the wiring harness. Ensure that all the seals are properly in place and ensure that the connectors are correctly coupled.
Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.
