Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if necessary for electrical inspections.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers if applicable.
2. Check tire pressure using a tire gauge and inflate to recommended PSI.
3. Inspect the tire tread depth with a tread depth gauge, replacing tires if they are worn below 2/32 of an inch.
4. Look for any visible signs of damage, such as cuts or bulges.

3. Wheel Alignment

Sub-steps:
1. Use a wheel alignment tool to check the alignment settings.
2. Adjust alignment as needed according to manufacturer specifications.
3. Test drive the vehicle to ensure it tracks straight.

4. Suspension Inspection

Sub-steps:
1. Visually inspect suspension components such as struts, shocks, and control arms for signs of wear or leakage.
2. Replace any damaged or worn parts using appropriate tools (e.g., socket set, torque wrench).
3. Ensure all fasteners are tightened to the manufacturer’s torque specifications.

5. Traction Control System Check

Sub-steps:
1. Connect an OBD-II scanner to the vehicle's diagnostic port.
2. Clear any traction control-related error codes and note any persistent issues.
3. If warning lights persist, further diagnose the traction control sensors and wiring for faults.
