To remove the brake light switch, start by moving the driver's seat fully to the rear for maximum working space. Disconnect the wiring plug from the brake light switch located at the top of the brake pedal bracket, then loosen the switch locknut and withdraw the switch from the bracket. For refitting, reverse the removal process. After fitting and reconnecting the switch, check its operation by having an assistant observe the brake lights while you push the brake pedal in by hand approximately 5 to 10 mm, adjusting the brake light switch so that the lights just turn off. Release the pedal and slowly press it again to ensure the brake lights illuminate before the pedal has traveled 15 mm. Additionally, the brake light can be adjusted by measuring the clearance between the switch plunger and the top of the pedal, comparing it with the specified measurement.

The brake light switch is located at the top of the brake pedal assembly and can be accessed by removing the trim panel beneath the steering column. It is responsible for opening and closing the brake light circuit, allowing current to flow to the brake lights when the pedal is pushed. If the brake lights do not work, check the fuse and bulbs. If those work, check that voltage is available at the switch. If there is not, there may be an open circuit between the fuse block and the switch and if there is but the lights do not work, there is an open circuit. When searching for it, check in between the switch and the light. To replace, begin by removing the trim panel below the steering column. Disengage the electrical connector, remove the locknut, then remove the switch. Installation is the reverse of removal, adjusting the switch afterward.

To replace the switch, the trim panel below the steering column should be removed, the electrical connector should be unplugged, the locknut should be removed, and then the switch can be removed from its bracket.

To install, simply reverse the removal process.

To detach the brake light switch from the pedal bracket, you need to loosen the locknut and then detach the switch.
