Solution

1. Preparation

Gather tools: socket set, wrenches, jack and jack stands, OBD-II scanner, and multimeter.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Check and Adjust Parking Brake Tension

Locate the parking brake adjustment mechanism under the vehicle near the rear axle.
Adjust the parking brake cable for proper tension by turning the adjuster clockwise to tighten or counterclockwise to loosen.
Ensure the parking brake lever has the correct amount of travel (typically 3-5 clicks).

3. Inspect and Replace Damaged Components

Cables:
1. Remove the rear wheels for access.
2. Inspect the parking brake cables for any signs of damage or fraying.
3. Replace any damaged cables with new ones, ensuring proper routing.
Brake Pedal Switch:
1. Locate the brake pedal switch above the brake pedal.
2. Disconnect the wiring harness and test the switch with a multimeter for continuity.
3. Replace the switch if it fails the continuity test.

4. Check Fluid Levels and Leaks

Inspect the brake fluid reservoir for any leaks or low fluid levels.
If the fluid is low, fill it to the manufacturer’s recommended level with the appropriate type of brake fluid.
Check for leaks in the brake lines and around the master cylinder. Replace any damaged components.

5. Reconnect and Test

Reconnect the battery and start the vehicle.
Ensure the parking brake light is no longer illuminated and test the parking brake functionality.
If the light remains on, further diagnosis may be required.
