1. Ensure that the ignition switch is in the OFF position.
2. Disconnect the vehicle control module (VCM) connector C1.
3. Turn the ignition switch to the RUN position.
4. Use a J 39200 DMM in order to measure the voltage from the VCM connector C1, cavity 9 to ground. Refer to Using Connector Test Adapters in Wiring Systems.

Did the voltage measure less than the specified value?

10.0 V

Go to Step 2

Go to Step 3

Locate and repair the open or short to ground in CKT 30 (PPL) between the VCM and the instrument cluster connector, cavity 16.

Go to Step 4

Go to Step 6

1. Turn the ignition switch to the OFF position.
2. Disconnect the instrument cluster.
3. Use a J 39200 DMM in order to measure the resistance between the instrument cluster connector, cavity 16 and the VCM connector C1, cavity 9.

Did the resistance measure greater than the specified value?

1.0 ohms

Go to Step 5

Go to Step 10

Locate and repair the open in CKT 30 (PPL) between the instrument cluster connector and the VCM connector C1.
