Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Ensure the vehicle is parked on a level surface with the parking brake engaged.
2. Inspect the Brake Pedal Position Switch
  • Locate the brake pedal position switch, usually mounted near the top of the brake pedal.
  • Using a multimeter, check for continuity when the brake pedal is pressed.
    • Tool Required: Multimeter
  • If the switch is faulty, remove it by disconnecting the wiring harness and twisting it counterclockwise to release it.
  • Install the new brake pedal position switch, ensuring it is securely fastened and connected.
3. Check Brake Fluid Level
  • Open the hood and locate the master cylinder reservoir.
  • Inspect the brake fluid level; it should be between the "MIN" and "MAX" marks.
    • If low, top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
  • Recheck the brake light after topping off the fluid.
4. Inspect Wiring and Connectors
  • Visually inspect the wiring harness and connectors leading to the brake lights and brake pedal switch.
  • Look for frayed wires, corrosion, or loose connections.
  • Repair or replace damaged wiring as necessary.
5. Test Brake Light Bulbs
  • Access the rear brake light assembly by removing the tail light cover.
  • Remove the brake light bulbs and visually inspect for any signs of damage (burnt filament).
  • Replace any faulty bulbs with OEM-specification replacements.
  • Reassemble the tail light cover and test the brake lights.
