Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove hubcaps if applicable and loosen lug nuts without fully removing them.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the tires.
4. Inspect the tread depth with a tread depth gauge; replace tires if tread is below 2/32 inches.
5. Check for any visible damage like cuts, bulges, or punctures. Replace damaged tires.
6. Reinstall tires and torque the lug nuts to the manufacturer's specifications (~90-100 ft-lbs).

3. Suspension Component Inspection and Repair

Sub-steps:
1. Inspect shock absorbers and struts for fluid leaks and proper damping.
2. Check control arms, bushings, and ball joints for wear; replace any components showing excessive play or damage.
3. If parts are damaged, remove the faulty component using appropriate tools (socket set, wrenches) and replace with OEM parts.
4. Reassemble and ensure all components are securely fastened.

4. Traction Control System Check

Sub-steps:
1. Reconnect the battery and turn on the ignition.
2. Use the OBD-II scanner to clear any fault codes related to the traction control system.
3. Conduct a test drive to verify the proper functioning of the traction control system.
