Solution

1. Preparation

Tools Required: OBD-II scanner, basic hand tools (socket set, wrenches), multimeter, fire extinguisher (for safety).
Ensure the vehicle is parked on a flat surface and turn off the ignition. Allow the vehicle to cool if it has been driving.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel covering the brakes.
2. Inspect brake pads for wear; if they are worn down, replace them.
3. Check the brake rotor for warping or overheating marks. Replace if necessary.
4. Reassemble the wheel and torque to manufacturer specifications (typically 100-120 ft-lbs).

3. Inspect Electrical Connections

Sub-steps:
1. Open the front trunk (frunk) and locate the main battery connections.
2. Visually inspect the wiring for any signs of melting or damage.
3. Disconnect any damaged connectors and replace them as needed.
4. Use a multimeter to check for continuity and proper voltage at the connections.

4. Battery Inspection

Sub-steps:
1. Safely access the battery pack by removing any protective covers.
2. Look for any signs of swelling, discoloration, or leaks.
3. If damage is found, contact a certified Tesla technician for battery replacement or repair.
