1. Preparation

Gather tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

Tools Required:

Socket set
Screwdriver set
Multimeter
OBD-II scanner

2. Inspect and Adjust Brake Light Switch

Locate the brake light switch, usually mounted above the brake pedal.
Remove any covers or panels if necessary to access the switch.
Check the alignment of the switch; it should be pushed in when the brake pedal is at rest.
If misaligned, adjust the switch position until it makes contact when the pedal is released.

3. Replace Brake Light Switch (if faulty)

Disconnect the wiring harness from the brake light switch.
Remove the switch from its mounting bracket using the socket set.
Install the new brake light switch in reverse order of removal.
Reconnect the wiring harness ensuring a secure fit.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Verify the fluid level is between the minimum and maximum marks on the reservoir.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Test the brake lights by pressing the brake pedal to ensure they turn off when the pedal is released.
Perform a test drive to confirm the issue is resolved.
