Solution

1. Preparation

Tools Required: OBD-II scanner for Tesla, multimeter, inspection mirror, safety gloves, and safety glasses.
Ensure the vehicle is parked on a level surface and turn off the power to the vehicle (power off through the touchscreen).

2. Inspect Components

Sub-steps:
- Visually inspect the condition of the drive belt and any rubber components.
- Check for any signs of melting or damage to the insulation of wiring near the motor or battery.
- Use an inspection mirror to check hard-to-see areas for signs of overheating.

3. Check Battery Coolant

Sub-steps:
- Locate the battery coolant reservoir and inspect the fluid level.
- If low, top off with the manufacturer-recommended coolant (Tesla's E-HEV coolant).
- Check for leaks in the coolant lines and connections.

4. Test Electrical Components

Sub-steps:
- Use a multimeter to test the voltage output of the battery.
- Confirm that all electrical connections are secure and free from corrosion.
- Test any relay or fuse associated with the motor and battery systems.

5. Replace Damaged Parts

Sub-steps:
- If any rubber components or the drive belt are damaged, remove them using a socket set.
- Install new parts according to manufacturer specifications, ensuring to torque any bolts to proper values.
- Reassemble any covers or shrouds that were removed during inspection.
