Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Ensure the vehicle is on a flat surface and securely parked.

2. Inspect the Brake Pedal Switch

Locate the brake pedal switch, typically mounted on the brake pedal assembly.
Remove any covers or panels obstructing access to the switch.
Check the switch for proper adjustment; it should activate and deactivate smoothly with the brake pedal movement.
If misaligned, adjust the switch position until it operates correctly.

3. Replace the Brake Light Switch (if needed)

If the switch is malfunctioning, disconnect the electrical connector from the switch.
Remove the switch from its bracket by unscrewing or unclipping as necessary.
Install the new brake light switch by reversing the removal process, ensuring it is securely mounted and connected.

4. Check the Brake Light Relay

Locate the fuse box; refer to the owner's manual for the specific location.
Identify the brake light relay and remove it.
Test the relay with a multimeter for continuity; replace if defective.
Reinstall the relay and ensure it is seated properly.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Press the brake pedal to verify the lights function correctly.
If the lights are still on, further investigation of wiring or additional components may be necessary.
