For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

- When Monitored:
When the Park Lamps are active.

- Set Condition:
When the Totally Integrated Power Module (TIPM) detects a short to voltage in the Fused Park Lamp Feed circuit.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. Clear all TIPM DTCs.
3. Turn the Park Lamps on.
4. With the scan tool, read the DTCs.
