Solution

1. Preparation

Gather tools: tire pressure gauge, jack, jack stands, lug wrench, alignment tools, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Tire Inspection and Replacement

Sub-steps:
1. Use a tire pressure gauge to check the pressure in each tire and inflate them to the recommended PSI.
2. Inspect each tire for tread depth using a tread depth gauge; replace any tires with worn tread (less than 2/32”).
3. Check for any visible damage, such as cuts or bulges; replace damaged tires.

3. Suspension Component Check

Sub-steps:
1. Raise the vehicle using the jack and secure it with jack stands.
2. Visually inspect struts and shocks for leaks or physical damage. Replace any worn or leaking components.
3. Check all control arms and bushings for signs of wear. Replace any that are cracked or broken.

4. Wheel Alignment

Sub-steps:
1. After ensuring all components are in good condition, take the vehicle to a professional alignment shop.
2. Follow their recommendations for any adjustments needed to align the wheels properly.

5. System Scan and Reset

Sub-steps:
1. Use an OBD-II scanner to check for active codes related to the traction control system.
2. Address any codes found by inspecting or replacing faulty sensors or components.
3. Clear any codes and test drive the vehicle to verify the systems are functioning correctly.
