Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box and identify the fuse for the electric parking brake (refer to the owner's manual).
Remove the fuse and inspect it for continuity; replace if blown.
Reinstall the new fuse and reconnect the battery terminal.

3. Replace Electric Parking Brake Actuator (if necessary)

Tools Required: Socket set, torque wrench
Remove the rear wheel to access the actuator.
Disconnect the electrical connector from the actuator.
Remove the bolts securing the actuator and take it out.
Installation of the new actuator:
- Position the new actuator in place.
- Secure it with the bolts and torque them to the manufacturer’s specifications.
- Reconnect the electrical connector.

4. Test Parking Brake Switch

Tools Required: Multimeter
Locate the parking brake switch, usually on the center console.
Disconnect the switch connector and check for continuity using a multimeter.
If faulty, replace the switch with a new one.

5. Reassemble and Test

Reinstall the rear wheel and lower the vehicle.
