Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the vehicle's battery to ensure safety while working on the electrical system.
2. Check Brake Fluid Level
  • Locate the brake fluid reservoir under the hood.
  • Ensure the fluid level is within the recommended range; top off with appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) if low.
3. Inspect Brake Light Switch
  • Locate the brake light switch, typically mounted near the brake pedal.
  • Remove the switch by unscrewing or unclipping it from its mounting.
  • Test the switch with a multimeter; it should show continuity when the pedal is pressed and no continuity when released.
  • Replace the switch if faulty.
4. Examine Wiring and Connectors
  • Visually inspect the wiring harness connected to the brake light switch and the brake lights for any signs of wear, fraying, or corrosion.
  • Repair or replace any damaged wiring or connectors as necessary.
5. Test Brake Pedal Position Sensor
  • If equipped, locate the brake pedal position sensor.
  • Disconnect the sensor and test it with a multimeter following the manufacturer's specifications.
  • Replace the sensor if it is found to be defective.
6. Reconnect Battery and Test
  • Reconnect the vehicle's battery.
  • Start the vehicle and check if the brake light is functioning properly.
  • Confirm that the light turns off after the engine is shut off.
