Solution

1. Tire Inspection and Replacement

Sub-steps:
- Remove the wheel covers or hubcaps if applicable.
- Inspect tires for tread depth using a tread depth gauge; replace if below 2/32".
- Check tire sidewalls for bulges or cuts; replace if damaged.
- Ensure tires are inflated to the manufacturer's recommended PSI (found on the driver’s door jamb).

2. Traction Control System Reset

Sub-steps:
- Use the OBD-II scanner to read and clear any stored codes related to the traction control system.
- Perform a system reset by disconnecting the vehicle’s battery for 10-15 minutes, then reconnect.
- Drive the vehicle for a short distance to verify that the traction control system is functioning correctly.

3. Suspension Component Repair

Sub-steps:
- Lift the vehicle using a hydraulic jack and secure it on jack stands.
- Inspect suspension components visually and by hand for movement or excessive play.
- Replace any damaged components (e.g., struts, shocks) following manufacturer specifications for torque values.

4. Wheel Alignment Adjustment

Sub-steps:
- Take the vehicle to a professional alignment shop.
- Ensure the alignment settings are adjusted to manufacturer specifications.
- Document the before and after alignment measurements for reference.
