Solution

Solution

1. Preparation

  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Adjust Brake Light Switch

  • Locate the brake light switch mounted on the brake pedal assembly.
  • Check the position of the switch; it should be fully depressed when the brake pedal is not engaged.
  • If misaligned, loosen the mounting screws and adjust the switch until it is correctly positioned. Re-tighten screws.

3. Test and Replace Brake Light Switch

  • If the switch is not functioning properly, disconnect the wiring harness from the brake light switch.
  • Use a multimeter to test for continuity. If there is no continuity when the pedal is released, replace the switch.
  • To replace, remove the old switch by unscrewing it from the bracket and install the new switch by reversing the procedure.

4. Reconnect Battery and Test

  • Reconnect the negative battery terminal.
  • Start the vehicle and test the brake lights by pressing the brake pedal to ensure they turn off when released.

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
  • Monitor the vehicle for a few days to ensure the issue does not recur
