PINPOINT TEST A : THE DRL (DAYTIME RUNNING LAMPS) ARE INOPERATIVE

A1 CHECK THE OPERATION OF THE HEADLAMPS

Ignition OFF.

Place the headlamp switch in the headlamps on position.

Do the headlamps operate correctly?

Does the ignition switch PID value agree with the ignition state?

Yes

GO to A3

No	REFER to: Steering Wheel and Column Electrical Components (211-05 Steering Column Switches, Diagnosis and Testing).

A3 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) 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?
