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 diagnose the headlamp system problem.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE
ATTEMPTING STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
If the headlamp high beam indicator lamp fails to light during the bulb test (about four seconds after the ignition switch is turned to the On position),
replace the headlamp high beam indicator lamp bulb with a known good unit. If the indicator lamp still fails to operate, diagnosis of the lamp, the
instrument cluster circuitry, the CCD data bus, or the Body Control Module (BCM) should be performed with a DRB scan tool as described in the
proper Computers and Control Systems/Body Control Module/Testing and Inspection Procedures.
