Solution

1. Preparation

Tools Required: Wheel chocks, jack, jack stands, tire pressure gauge, OBD-II scanner
Sub-steps:
- Park the vehicle on a flat surface and engage the parking brake.
- Place wheel chocks behind the rear tires for safety.
- Gather necessary tools for inspection and repairs.

2. Tire Inspection and Replacement (if necessary)

Sub-steps:
- Remove the affected tire using a lug wrench.
- Inspect the tire for any signs of damage, such as cracks, bulges, or foreign objects.
- Check tire pressure and adjust to the manufacturer's specifications (usually found in the driver's side door jamb).
- If damage is found, replace with a new tire, tightening the lug nuts to the manufacturer’s torque specifications (usually 80-100 ft-lbs for most vehicles).

3. Brake System Inspection and Repair

Sub-steps:
- Remove the wheel to access the brake components.
- Inspect the brake pads and rotors for wear; replace if pads are less than 3mm thick or if the rotors show signs of excessive wear.
- Check the calipers for proper function; replace any that are sticking or leaking brake fluid.
- Ensure that all bolts are torqued to the manufacturer’s specifications.

4. Electrical System Inspection

Sub-steps:
- Inspect wiring harnesses and connectors under the hood and near the battery for signs of melting or damage.
- Check for any loose connections or frayed wires that could be causing electrical shorts.
- Use an OBD-II scanner to check for any fault codes that might indicate electrical issues.
