- HCM
- P1 CHECK VEHICLE HISTORY
- Check vehicle history for recent service actions with the HCM.
Where there any recent HCM service actions?
Yes PERFORM the PMI procedure as directed by the scan tool. REFER to: Module Programming . No GO to P2 - P2 CHECK FOR CORRECT HCM (HEADLAMP CONTROL MODULE) OPERATION
- Disconnect and inspect the HCM and related in-line connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the HCM and related in-line connectors. Make sure it seats and latches correctly.
- Operate the system and determine if the concern is still present.
