Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, jack, jack stands, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during inspection.

2. Tire Inspection and Replacement

Sub-steps:
1. Use a tire pressure gauge to check the air pressure in all tires. Inflate or deflate as necessary to meet manufacturer specifications.
2. Inspect the tread depth; replace tires if tread is below 2/32 inches.
3. Check for any punctures or sidewall damage; repair or replace tires as needed.
4. If tires are unevenly worn, consult a professional for a wheel alignment.

3. Suspension Component Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect suspension components for any signs of wear or damage (cracks, rust, or broken parts).
3. Replace any damaged components using the appropriate OEM parts, ensuring to torque bolts to the manufacturer's specifications.

4. Traction Control System Check

Sub-steps:
1. Reconnect the battery and use an OBD-II scanner to check for any error codes related to the traction control system.
2. Inspect the wheel speed sensors for any damage or dirt; clean or replace as necessary.
3. Clear any error codes and test drive the vehicle to ensure the traction control system is functioning properly.
