Solution

1. Preparation

Gather necessary tools and materials before starting the process.
Tools Required:
- OBD-II scanner (if error codes are present)
- Socket set
- Multimeter (for testing switch operation)
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it’s below the minimum line, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Close the reservoir cap securely after checking.

3. Check Brake Light Switch

Locate the brake light switch, usually found near the brake pedal.
Use a multimeter to test the switch for continuity while pressing the brake pedal.
If the switch is faulty, disconnect the switch and replace it with a new one. Follow these sub-steps:
- Disconnect the wiring harness from the switch.
- Remove the switch using a socket or wrench.
- Install the new switch and reconnect the wiring harness.

4. Reset the System

If the brake light issue persists after checking the fluid and switch, reset the vehicle's electronic system.
Disconnect the negative terminal of the battery using a socket wrench.
Wait for approximately 10 minutes to allow any residual power to dissipate.
Reconnect the negative terminal and tighten it securely.
