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 battery terminal to prevent electrical shorts.

2. Inspect and Top Off Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and check the fluid level.
If low, add the appropriate brake fluid (DOT 3 or as specified in the owner's manual) until it reaches the full mark.
Replace the cap and reconnect the battery.

3. Check and Adjust Parking Brake Lever

Inspect the parking brake lever for any looseness.
If necessary, adjust the parking brake cable by locating the adjustment nut under the vehicle.
Tighten the nut until the parking brake lever has a firm feel but does not engage excessively.

4. Test the 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 test the switch for continuity. If there is no continuity when the switch is engaged, replace the switch.

5. Inspect Wiring and Connectors

Examine the wiring harness for frays or breaks, especially near the parking brake assembly.
Clean any corroded connectors and ensure all connections are secure.
Repair or replace any damaged wiring as needed.

6. Final Assembly and Testing

Reconnect all components, including the parking brake switch.
Reattach the negative battery terminal.
Test the parking brake by applying and releasing it several times, ensuring the light turns off when properly engaged.
