NOTE: Ensure the park lamps are still on.

Is the voltage above 5.0 volts?

Yes

- Go To 5

No

- Go To 3

3. CHECK THE (Z905) GROUND CIRCUITS FOR AN OPEN

2. Using a 12-volt test light connected to 12-volts, check the (Z905) Ground circuits.

Does the test light illuminate brightly?

Yes

- Go To 4

No

- Repair the (Z905) Ground circuits for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. CHECK THE (Q413) POWER SLIDING DOOR LOCKOUT SENSE CIRCUIT FOR AN OPEN




1. Disconnect the Instrument Cluster C2 harness connector.
