Test Step 1. Inspect Electrical Connectors
and Wiring
A. Turn the keyswitch to the OFF position.
B. Thoroughly inspect P1 connector and the lamp
connections. Refer to Troubleshooting, "Electrical
Connectors - Inspect" for details.
C. Perform a 45 N (10 lb) pull test on each of the
wires in the customer connector and the ECM
connector that are associated with the diagnostic
lamp.
D. Check the screw for the P1 connector for the
correct torque of 5.0 N·m (44 lb in).
E. Check the harness for abrasions and for pinch
points from the battery to the ECM.
Results:
•
OK – Proceed to Test Step 2.
•
Not OK
Repair: Repair the connectors or the harness
and/or replace the connectors or the harness.

Verify that the repair eliminates the fault.
STOP.
Test Step 2. Inspect the Lamp, the Fuse,
and the Power Supply
A. Disconnect the lamp from the harness. Inspect the
lamp in order to determine if the lamp has failed.
B. Measure the resistance across the two terminals
of the lamp. If the resistance is more than 2000
Ohms, the bulb has failed.
C. Check the battery by connecting a test lamp
across the terminal of the battery.
Expected Result:
The lamp has less than 2000 Ohms and the power
supply is OK.
Results:
•
OK – The lamp appears to be operating correctly
at this time. Proceed to Test Step 3.
•
Not OK
