Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace EPB Switch

Remove the center console cover to access the EPB switch.
Disconnect the wiring harness from the switch.
Replace the EPB switch with a new one if damaged.
Reconnect the wiring harness and reassemble the center console.

3. Check and Replace Parking Brake Actuator

Locate the parking brake actuator, typically found near the rear brakes.
Disconnect the wiring harness and remove any mounting bolts securing the actuator.
Inspect the actuator for damage; replace if necessary.
Install the new actuator by reversing the removal steps, ensuring all connections are secure.

4. Brake Fluid Check and Adjustment

Check the brake fluid reservoir for proper fluid level.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or around the master cylinder.

5. System Reset

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any fault codes and reset the parking brake system.
Perform a functional test of the EPB to ensure it engages and disengages smoothly.
