Visual Inspection and Pre-checks
- Inspect the headlamp switch for damage.
- Inspect the light sensor for damage.
|
A1 CHECK THE MANUAL HEADLAMP OPERATION |
-
Place the headlamp switch in the HEADLAMPS and then OFF positions.
Do the headlamps operate correctly?
No |
REFER to: Headlamps (417-01 Exterior Lighting, Diagnosis and Testing).

|
A2 CHECK FOR VOLTAGE TO THE LIGHT SENSOR |
-
Disconnect: Autolamp Sensor C287 (vehicles with EMTC ).
-
Disconnect: Autolamp/Sunload Sensor C286 (vehicles with DATC ).
-
Place the headlamp switch in the AUTOLAMPS position.

A8 CHECK FOR CORRECT BCM (BODY CONTROL MODULE)
OPERATION |
-
Disconnect and inspect all BCM and all 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 BCM and all related in-line 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 Technical Service Bulletins (TSBs). If a
TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB
instructions. If no Technical Service Bulletins (TSBs) address this
concern, INSTALL a new BCM . REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).
|
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.
