Hi-Beam Indicator Lamp: Testing and Inspection
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 Lighting and Horns/Headlamp for diagnosis of the headlamp system. If no headlamp system problems are
found, the following procedure will help locate an open in the high beam indicator lamp circuit.
1. Check that the headlamp high beams are functional. If OK, go to Step 2. If not OK, refer to Lighting and Horns/Headlamp for diagnosis of the
headlamp system.
2. Disconnect and isolate the battery negative cable. Remove the instrument cluster bezel and the cluster assembly. Unplug the left instrument cluster
wire harness connector.
3. Connect the battery negative cable. Turn the headlamps on and select the high beams with the multi-function switch stalk. Check for battery
voltage at the high beam indicator lamp driver circuit cavity of the left instrument cluster wire harness connector. If OK, replace the faulty bulb. If
not OK, repair the open circuit to the headlamp dimmer (multi-function) switch as required.
