Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal from the battery to prevent electrical shorts.

2. Check Brake Fluid Level

Locate the brake fluid reservoir, usually found near the driver's side of the engine compartment.
Remove the cap and visually inspect the fluid level.
If low, top off with manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
Reinstall the cap securely.

3. Inspect Parking Brake Switch

Locate the parking brake switch, typically found near the parking brake lever.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity. If no continuity is found, replace the switch.

4. Adjust Parking Brake Cables

Locate the parking brake adjustment mechanism, usually located under the vehicle.
If the cables are too loose, adjust the tension according to the manufacturer specifications.
Ensure the parking brake lever engages and disengages smoothly.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and test the parking brake to ensure the warning light is no longer illuminated.
