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

- When Monitored:
With the Headlamps activated.

- Set Condition:
When the BCM detects a LOW condition.





1. INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the Scan Tool, clear all BCM DTCs.
3. Turn the High beam Headlamps on.
4. With the Scan Tool read the DTC information.

Does the Scan Tool read: 900C-LEFT HIGH BEAM CONTROL CIRCUIT LOW-BCM?

Yes

- Go To 2

No

- The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.
- Perform the BODY VERIFICATION TEST. Verification Tests

2. LEFT HIGH BEAM OUTPUT CIRCUIT




1. Turn the ignition off.
2. Disconnect the BCM C7 harness connector.
3. Disconnect the Left Headlamp harness connector.
4. Measure the resistance between ground and the Left Highbeam Output circuit.

Is the resistance below 5.0 ohms?

Yes

- Repair the Left Highbeam Output circuit for a short to ground condition.
- Perform the BODY VERIFICATION TEST. Verification Tests

No

- Replace the Body Control Module (BCM).
- Perform the BODY VERIFICATION TEST. Verification Tests
