Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Connect the Tesla to a charger if battery levels are low.
Gather tools such as a diagnostic tool, multimeter, and inspection camera if needed.

2. Battery Health Check

Access the vehicle's settings menu and navigate to the battery section.
Check the battery's state of health (SoH) and state of charge (SoC).
If the SoH is below 80%, consider replacing the battery pack.

3. Check Traction Control System

Use the diagnostic tool to check for any error messages related to the traction control system.
If any faults are found, proceed to reset the traction control and perform a recalibration.

4. Inspect Drive Motors

Remove the undercarriage cover (if applicable) to access the drive motors.
Visually inspect the drive motors for any signs of overheating or damage.
Use a multimeter to check the resistance of the motor windings; replace if out of spec.

5. Software Update

Ensure the vehicle is running the latest software version.
Head to the software section in the settings to check for available updates and install them.
