Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Check each tire for tread depth using a tread depth gauge; replace tires with less than 3mm of tread.
2. Inspect for any visible damage, such as cuts or bulges.
3. Inflate tires to the manufacturer-recommended PSI.
4. If replacement is necessary, remove the old tires using a socket set.
5. Install new tires, ensuring they are mounted in accordance with the vehicle's rotation direction.

2. Traction Control System Reset

Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine.
2. Use an OBD-II scanner to clear any existing error codes related to the traction control system.
3. Start the engine and check if the warning light has turned off.
4. Perform a test drive to ensure the traction control system is functioning correctly.

3. Suspension Component Inspection and Repair

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure with jack stands.
2. Visually inspect struts and shocks for leaks or wear.
3. Check bushings for cracks or deterioration.
4. Replace any worn components with OEM parts, tightening to manufacturer torque specifications.
5. Lower the vehicle and test drive to assess improvement.
