Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a flat surface and secure with wheel chocks.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Check Brake Fluid Level
  • Locate the master cylinder reservoir.
  • Remove the cap and inspect the brake fluid level; add fluid if it’s low (use the recommended brake fluid type).
  • Reinstall the cap securely.
3. Inspect Brake Light Switch
  • Locate the brake light switch, typically mounted near the brake pedal.
  • Check the switch for proper alignment and function; adjust if necessary.
  • If faulty, replace the switch by disconnecting the wiring harness and unscrewing the switch from its mount.
4. Examine Wiring and Connectors
  • Visually inspect the brake system wiring for frays, breaks, or corrosion.
  • Clean any corroded connectors with electrical contact cleaner.
  • Repair or replace any damaged wires or connectors as needed.
5. Test the Brake Pedal Position Sensor
  • If equipped, locate the brake pedal position sensor.
  • Use a multimeter to test the sensor's output while depressing the brake pedal; refer to the service manual for specific voltage readings.
  • Replace the sensor if it does not produce the expected readings.
