Inspection and Verification
1. Verify the customer concern.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
NOTE: Make sure the headlamp switch is in the OFF position.
NOTE: Make sure the multifunction switch is in the low beam position.
4. If the cause is not visually evident, connect the WDS or equivalent Tester to the data link connector and Smart Junction Box (SJB) Diagnostic
Trouble Code (DTC) Index select the vehicle to be tested from the WDS or equivalent Tester menu. If the WDS or equivalent Tester does not
communicate with the vehicle;
-
