Solution

1. Preparation

Gather tools: tire pressure gauge, jack, jack stands, torque wrench, OBD-II scanner, and a multimeter.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Tire Pressure Check
- Use a tire pressure gauge to check the pressure in all tires.
- Inflate or deflate tires as necessary to match the manufacturer’s specifications.
Tread Depth and Damage Inspection
- Use a tread depth gauge to measure the tread on each tire. Replace tires if tread depth is below 2/32".
- Inspect tires visually for any visible damage; replace any damaged tires.

3. Suspension Inspection and Repair

Visual Inspection
- Lift the vehicle using a jack and secure it with jack stands.
- Check all suspension components for signs of wear or damage (e.g., bushings, struts).
Component Replacement
- Replace any worn or damaged parts (e.g., struts, bushings) as needed, following the manufacturer's torque specifications.

4. Wheel Alignment

Perform a wheel alignment using a professional alignment rack to ensure all wheels are aligned according to specifications.

5. Traction Control System Check

OBD-II Scan
- Use an OBD-II scanner to check for any fault codes related to the traction control system.
- Address any codes by following the manufacturer's repair procedures.
System Functionality Test
- Test the traction control system in a safe environment to ensure it operates correctly.
