Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Inspect brake pads for thickness; if worn down to less than 3mm, they need replacement.
- Measure the rotor thickness; if below specifications, replace the rotors.
Replace Brake Pads:
- Remove the caliper bolts using a torque wrench.
- Slide the caliper off and support it without stressing the brake line.
- Replace the brake pads and reassemble the caliper.
- Torque caliper bolts to manufacturer specifications.

3. Check Electrical Components

Inspect Wiring and Connectors:
- Examine the wiring harness for frays or melting.
- Clean any corroded connections with electrical contact cleaner.
- Replace damaged wiring or connectors as necessary.
Check Battery Pack:
- Remove the battery cover if accessible.
- Inspect for any signs of overheating or damage.
- If damage is observed, consult a Tesla service center for potential battery replacement.

4. Reconnect Battery and Test

Reconnect the 12V battery.
Start the vehicle and monitor for any abnormal smells or warning lights.
Test drive the vehicle to ensure the burning smell does not return.
