Solution

1. Preparation

Tools Required: Socket set, screwdrivers, OBD-II scanner, multimeter, jack and jack stands
Safety Warnings: Ensure the vehicle is on a flat surface and set in 'Park'. Disconnect the battery before working on electrical components.

2. Inspect the Parking Brake Switch

Locate the parking brake switch, typically found near the parking brake lever.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter to ensure it is functioning correctly (should show continuity when engaged).
Replace the switch if defective.

3. Check Parking Brake Cables

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the parking brake cables for any signs of damage or binding.
If any cables are damaged, replace them with OEM parts.
Adjust the cables if they are too loose or too tight, following the service manual specifications.

4. Inspect Rear Brake Calipers

Remove the rear wheels to gain access to the brake calipers.
Check for proper operation of the calipers; ensure they can move freely and are not seized.
If calipers are stuck, clean them and apply lubricant to moving parts. If they are severely damaged, replace them.

5. Reconnect Battery and Test

Reconnect the battery after all inspections and repairs are done.
Test the parking brake functionality by engaging and disengaging it multiple times to ensure it operates smoothly.
