Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle battery to prevent electrical issues during repair.

2. Inspect and Replace Components

2.1. Inspect the Electronic Parking Brake Switch

Remove the center console trim to access the electronic parking brake switch.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter for continuity.
If defective, replace the switch with a new unit.

2.2. Check and Replace Brake Pads and Rotors

Lift the vehicle using a jack and secure it with jack stands.
Remove the rear wheels to access the brake assembly.
Inspect the brake pads for wear; replace if they are below the minimum thickness.
Check the rotors for scoring or damage; replace if necessary.

3. Test the Electronic Parking Brake Actuator

Reconnect the battery and use the OBD-II scanner to run an actuator test.
If the actuator does not respond, remove it from the vehicle.
Replace the actuator if it is found to be faulty.

4. Reassemble and Final Checks

Reinstall the wheels and lower the vehicle.
Reattach the center console trim.
Test the emergency brake to ensure proper engagement and release.
