The diagnosis found here addresses an inoperative headlamp high beam indicator lamp condition. If the problem being diagnosed is related to inoperative headlamp high beams, refer to Headlamp Diagnosis in the Diagnosis and Testing section of Group 8L - Lamps for diagnosis of the headlamp system.

For complete circuit diagrams, refer to Instrument Cluster in the Contents of Group 8W - Wiring Diagrams.
(1) Disconnect and isolate the battery negative cable. Remove the instrument cluster.
(2) Connect the battery negative cable. Turn the headlamps on and select the high beams with the multi-function switch stalk.
