Hi-Beam Indicator Lamp: Testing and Inspection
HARD WIRED LAMP DIAGNOSIS
Each of the lamps found in this depends upon a hard wired circuit input to the instrument cluster for proper operation. The following procedures
will help to diagnose conditions that may cause an inoperative hard wired lamp circuit condition.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS AND SEAT BELTS/AIRBAGS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT

Headlamp High Beam Indicator Lamp
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 of Headlamps 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. 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. Check for battery
voltage at the high beam indicator driver circuit cavity of the instrument cluster wire harness connector B. If OK, replace the faulty headlamp
high beam indicator lamp bulb. If not OK, repair the open high beam indicator driver circuit to the headlamp dimmer (multi-function) switch
as required.
