Brake Light Switch: Adjustments

WARNING: TO AVOID PERSONAL INJURY OR DEATH, ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, AIRBAG, SEAT BELT TENSIONER, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT.

1. Disconnect and isolate the battery negative cable.
2. Depress and hold the brake pedal in the depressed position until the brake lamp switch adjustment is completed.
3. Pull the plunger of the brake lamp switch outward from the switch body to its travel limit.

NOTE: Do not pull the brake pedal upwards as this will adjust the switch plunger to an incorrect position. The switch is properly adjusted when the switch plunger is just contacting (no gap) the brake pedal arm with the pedal in the relaxed (released) position.

4. Release the brake pedal from its depressed position to automatically adjust the brake lamp switch plunger.
