Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and securely lift it using a jack.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace the Parking Brake Switch

Locate the parking brake switch, usually found near the parking brake lever.
Disconnect the electrical connector from the switch.
Remove the switch from its mounting bracket.
Install the new parking brake switch by reversing the removal steps.
Reconnect the electrical connector ensuring it clicks into place.

3. Check and Replace the Brake Fluid

Locate the brake fluid reservoir, typically found near the back of the engine bay.
Remove the reservoir cap and check the fluid level; add brake fluid if necessary (use DOT 4 fluid as specified by the manufacturer).
If fluid is low, inspect for leaks in brake lines or at the calipers.

4. Adjust the Parking Brake

If applicable, adjust the parking brake cable tension according to manufacturer specifications.
Ensure the parking brake lever engages firmly and the vehicle does not roll when parked.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and check if the parking brake warning light is still illuminated.
Engage and disengage the parking brake several times to ensure proper function.
