Yes	For vehicles with halogen fog lamps, INSTALL a new for lamp bulb. Fog Lamp Bulb For vehicles with LED fog lamps, INSTALL a new fog lamp assembly. Daytime Running Lamps (DRL) .
No	REPAIR the circuit.

F4 CHECK FOR CORRECT BCM OPERATION

Disconnect and inspect all BCM 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 BCM connectors. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, BCM Hardware Testing .
No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
