Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the regular brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Test the Parking Brake Switch

Remove the center console cover to access the parking brake switch.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity when engaged.
- If continuity is not present, replace the switch.

3. Check and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, top off with the recommended brake fluid type (usually DOT 4).
Recheck the parking brake functionality after topping off.

4. Inspect Parking Brake Actuator and Cables

Locate the parking brake actuator and visually inspect it for any signs of damage or corrosion.
Check the cables for fraying or disconnection.
If any damage is found, replace the respective components.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and engage the parking brake.
Check for warning messages and test the operation of the parking brake, ensuring it engages and releases smoothly.
