Grand Cherokee 2WD V6-3.7L (2008)
Brake Light Switch: Adjustments
BRAKE LAMP SWITCH
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before
attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, 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 SRS. Failure to take the proper precautions could result in accidental
airbag deployment.
1. Disconnect and isolate the battery negative cable.
2. Remove the steering column opening cover from the instrument panel. See: Body and Frame/Interior Moulding / Trim/Dashboard / Instrument
Panel/Service and Repair/Steering Column Opening Cover - Removal.
3. Depress and hold the brake pedal in the depressed position.
4. Pull the brake lamp switch plunger all the way out of the switch housing to its fully extended position.
CAUTION: Brake booster damage may occur if the brake pedal pull exceeds about 9 kilograms (20 pounds).
5. Release the brake pedal. Then pull the pedal lightly upward to its normal at-rest position. The pedal will set the plunger to the correct position as
the pedal pushes the plunger into the switch housing. The switch plunger will make a light audible ratcheting noise as it self-adjusts.
6. Reinstall the steering column opening cover onto the instrument panel. See: Body and Frame/Interior Moulding / Trim/Dashboard / Instrument
Panel/Service and Repair/Steering Column Opening Cover - Installation.
7. Reconnect the battery negative cable.
