Step 1: Hold down both scroll wheels on the steering wheel until the screens go black and the Tesla logo appears.
Step 2: Wait for the system to reboot (approximately 30 seconds).
Step 3: Attempt to release the parking brake after the reboot.

3. Check for Fault Codes:

Step 1: Use the Tesla mobile app or vehicle interface to check for any alerts or fault codes related to the parking brake system.
Step 2: Document any error messages displayed.

Tools Required:

Tesla mobile app or vehicle interface for software updates and diagnostics.
OBD-II scanner compatible with Tesla (if needed for deeper diagnostics).
Torque wrench (if mechanical adjustments or replacements are necessary).
Basic hand tools for potential mechanical repairs (screwdrivers, sockets, etc.).

Repair Instructions:

If the above steps do not resolve the issue, further mechanical inspection may be necessary.

1. Inspect the Parking Brake Mechanism:

Step 1: Ensure the vehicle is safely parked on a level surface and turned off.
Step 2: Using a socket wrench, remove the rear wheels to gain access to the rear brake assembly.
Step 3: Inspect the parking brake cable and mechanism for any visible damage or disconnection.

Step 2: If you have access to an OBD-II scanner, check for specific codes related to the parking brake actuator.

3. Manually Release the Parking Brake:

Step 1: If the parking brake is stuck, you may need to manually override it. Locate the manual release mechanism (refer to the owner's manual for the exact location).
Step 2: Use a flathead screwdriver or similar tool to activate the manual release, if applicable.

4. Reassemble and Test:

Step 1: After making any necessary adjustments or repairs, reassemble the wheel and components.
Step 2: Replace the tire, lower the vehicle, and turn on the ignition.
Step 3: Attempt to release the parking brake again and check for proper operation.

When to Seek Professional Help:

If the parking brake still does not release after following these steps, it’s advisable to contact Tesla Service or a qualified automotive technician. They will have specialized tools and knowledge to diagnose and repair electronic or complex mechanical issues.
