Solution
1. Preparation
  • Gather necessary tools and safety gear.
  • Disconnect the vehicle battery to prevent electrical shock.
2. Inspect Brake Light Switch
  • Locate the brake light switch mounted on the brake pedal assembly.
  • Verify that the switch is properly aligned and not stuck in the 'on' position.
  • If misaligned, adjust the switch position so it activates only when the brake pedal is pressed.
3. Test Brake Light Switch
  • Reconnect the battery.
  • Use a multimeter to check for continuity in the brake light switch when the pedal is pressed and released.
    • If there is continuity when the pedal is pressed but none when released, the switch is functioning properly.
    • If there is continuity when the pedal is not pressed, the switch is faulty and needs replacement.
4. Replace Brake Light Switch (if necessary)
  • Disconnect the wiring harness from the brake light switch.
  • Remove the switch from the bracket by turning it counterclockwise.
  • Install the new switch by reversing the removal steps and ensure it is securely fastened.
  • Reconnect the wiring harness, ensuring a snug fit.
5. Final Checks
  • Reconnect the vehicle battery.
  • Test the brake lights by pressing the brake pedal to ensure they turn off when the pedal is released.
  • Check for any wiring issues or further faults.
