Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Test Parking Brake Switch

Locate the parking brake switch, usually found near the parking brake lever.
Remove the trim panel covering the switch if necessary.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity when activated; replace if faulty.

3. Check Brake Fluid Level

Locate the master cylinder reservoir, typically near the driver's side of the engine bay.
Inspect the brake fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Look for any leaks in the brake system that might cause fluid loss.

4. Inspect the Parking Brake System

Check the parking brake lever and ensure it fully disengages.
Inspect the parking brake cables for fraying or damage. Replace if necessary.
If the parking brake shoes are worn, replace them according to manufacturer specifications.

5. Reassemble and Reconnect

Reconnect any electrical connectors and trim panels that were removed.
Ensure all tools and equipment are removed from the vehicle.
Reconnect the negative battery terminal.
