Solution

1. Preparation

Gather tools and parts for inspection and repair.
Disconnect the vehicle from the charger and ensure it is in a safe, well-ventilated area.
Wear appropriate safety gear including gloves and safety glasses.

2. Inspect and Replace Tires (if necessary)

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Check tire pressure and tread depth; inflate or replace tires as necessary.
If any damage is found (such as bulging or severe wear), replace the affected tire(s).
Reinstall the wheels and torque to manufacturer specifications (typically around 80-100 ft-lbs).

3. Examine and Service the Brake System

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench.
Remove the wheel to access the brake calipers and pads.
Inspect brake pads for wear and replace if they are worn down to the indicator.
Check for signs of brake drag; ensure caliper slides are lubricated.
Reinstall the wheel and torque to manufacturer specifications.

4. Inspect Electric Motor and Components

Tools Required: Multimeter, socket set, torque wrench.
Check electric motor connections for signs of overheating or damage.
Use a multimeter to test for proper voltage and continuity in the wiring harness.
If any components are damaged, consult the service manual for replacement procedures.

5. Final Inspection and Reassembly

Recheck all connections and ensure no tools are left in the engine bay.
Reconnect the battery and perform a system check to clear any error codes.
Test drive the vehicle to confirm that the burning smell has been resolved.
