Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection and Replacement

Check Tread Depth:
- Use a tread depth gauge to measure tread on all tires.
- Replace tires if tread depth is below 2/32 inches.
Check for Damage:
- Inspect tires for cracks, bulges, or punctures.
- Replace damaged tires as necessary.
Tire Pressure Adjustment:
- Use a tire pressure gauge to check tire pressure.
- Inflate tires to recommended specifications found in the owner’s manual.

3. Traction Control System Inspection

OBD-II Scan:
- Connect the OBD-II scanner to the vehicle's diagnostic port.
- Check for any diagnostic trouble codes (DTCs) related to traction control.
- Clear codes if applicable and retest the system.
System Test:
- Drive the vehicle in a safe area and monitor the traction control system operation.
- Confirm that the system engages when necessary during acceleration.

4. Suspension Component Inspection

Visual Inspection:
- Inspect struts, shocks, and bushings for signs of wear or leaks.
- Replace any worn or damaged components as necessary.
Alignment Check:
- Have the vehicle's alignment checked and adjusted by a professional if necessary.
