Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Inspect the Parking Brake Lever

Pull the parking brake lever up slightly to ensure it is fully released.
If the lever feels stuck, inspect the linkage for obstructions or damage.

3. Check Brake Fluid Level

Locate the brake master cylinder reservoir.
Remove the cap and check the fluid level; top off with the recommended brake fluid type if low (typically DOT 3 or DOT 4).
Reattach the cap securely.

4. Test the Parking Brake Switch

Locate the parking brake switch, usually found near the base of the parking brake lever.
Disconnect the wiring harness from the switch and check for continuity using a multimeter.
If the switch is faulty, replace it with a new one.

5. Inspect Parking Brake Cables

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the parking brake cables for fraying, corrosion, or disconnection.
If damaged, replace the cables as necessary.

6. Test Brake Fluid Level Sensor

Disconnect the wiring harness from the brake fluid level sensor located in the master cylinder reservoir.
Use a multimeter to check for continuity; replace the sensor if it is faulty.
