Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear or bulges.
- Remove any debris lodged in the tread.
Replace Tires if Necessary:
- Use a jack to lift the vehicle and remove the wheel nuts with a socket set.
- Replace the tire and torque the wheel nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Brake System Inspection and Maintenance

Check Brake Pads and Rotors:
- Remove the wheel to access the brake assembly.
- Inspect pads for excessive wear; replace if less than 3 mm thickness.
- Check rotors for warping or overheating signs; replace if necessary.

4. Electrical System Inspection

Check Wiring and Components:
- Inspect the wiring harness for frayed wires or burnt insulation.
- Look at the electric motor for signs of overheating or damage.
Repair or Replace Wiring:
- If damage is found, cut and splice new wiring or replace the affected component.

5. System Reset

Perform System Reset:
- Disconnect the 12V battery for 10 minutes to reset the vehicle’s systems.
- Reconnect the battery and check for any persistent warning lights.
