Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Wear safety gloves and goggles.

2. Tire Inspection and Replacement

Sub-steps:
1. Check tire tread depth using a tread gauge. Replace tires if tread is below 2/32 of an inch.
2. Inspect tires for bulges, cracks, or punctures that may require replacement.
3. Ensure all tires are inflated to the manufacturer’s recommended PSI (refer to the owner's manual).
4. If tire replacement is necessary, remove the wheel using a socket set, replace with new tires, and torque lug nuts to the manufacturer's specification (usually around 76-80 ft-lbs).

3. Suspension System Check

Sub-steps:
1. Use a jack to lift the vehicle and support it securely with jack stands.
2. Visually inspect suspension components for wear, such as struts, shocks, and control arms.
3. Replace any worn or damaged components with OEM or quality aftermarket parts.
4. Reassemble and lower the vehicle back to the ground.

4. Brake System Inspection

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Check brake pads for thickness; replace if less than 3mm.
3. Inspect rotors for warping or wear; replace if necessary.
4. Reassemble and ensure calipers are functioning correctly.

5. Traction Control System Diagnostics

Sub-steps:
1. Connect the OBD-II scanner to retrieve any fault codes related to the traction control system.
2. Follow manufacturer guidelines to clear any codes and perform a system reset if applicable.
3. Test drive the vehicle to check if the traction control system functions appropriately.
