Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Thoroughly inspect the terminal connections on the P2/J2 ECM connector and the solenoids. Refer to Troubleshooting, "Electrical Connectors - Inspect".
B. Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector and the solenoid connectors that are associated with the active diagnostic code.
C. Check the screw for the ECM connector for the correct torque of 6 N m (53 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.
Result: All connectors, pins, and sockets are correctly coupled and/or inserted. The harness is free of corrosion, abrasion, and pinch points.
Proceed to Test Step 2.
2. Check for Active Diagnostic Codes
A. Turn the keyswitch to the OFF position.
B. Connect the electronic service tool to the diagnostic connector.
C. Turn the keyswitch to the ON position. Wait at least 20 seconds for activation of the diagnostic codes.
D. Verify if any of the diagnostic codes that are listed in Table 1 are active.
E. Turn the keyswitch to the OFF position.
Diagnostic codes
Result: A -5 diagnostic code is active.
Proceed to Test Step 3.
Result: A -6 diagnostic is active.
Proceed to Test Step 5.
3. Create a Short Circuit at the Harness Connector for the Solenoid
A. Turn the keyswitch to the
