Remove the cap and check the fluid level; top off with the appropriate brake fluid if low.
Reinstall the cap securely.

3. Inspect and Replace Parking Brake Switch

Locate the parking brake switch, which is typically near the center console.
Disconnect the electrical connector and remove the switch using a socket set.
Test the switch with a multimeter for continuity; replace if faulty.
Reinstall the new switch and reconnect the electrical connector.

4. Examine Rear Brake Calipers

Lift the rear of the vehicle using a jack and secure with jack stands.
Remove the rear wheels using a socket set.
Inspect the calipers for proper operation of the parking brake mechanism; clean or replace if necessary.
Ensure the caliper pistons move freely and there is no debris blocking the movement.

5. Reset the Electronic Parking Brake

Reconnect the negative battery terminal.
Use the OBD-II scanner to reset any fault codes associated with the electronic parking brake.
Perform a system check to ensure the parking brake is functioning correctly.
