Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Measure tread depth using a tread depth gauge; replace tires if tread is below 2/32".
2. Inspect sidewalls for any bulges, cracks, or punctures that could affect performance.
3. If necessary, replace tires with ones suited for wet conditions, ensuring they meet the manufacturer’s specifications.
Tools Required: Tread depth gauge, jack, jack stands, lug wrench.

2. Tire Pressure Adjustment

Sub-steps:
1. Remove valve caps from each tire.
2. Use a tire pressure gauge to check current tire pressures.
3. Inflate or deflate tires to match recommended pressures stated on the driver’s door jamb label.
Tools Required: Tire pressure gauge, air compressor or tire inflator.

3. Traction Control System Check

Sub-steps:
1. Connect an OBD-II scanner to the vehicle's diagnostic port.
2. Retrieve and record any fault codes related to the traction control system.
3. Clear codes and perform a test drive to see if any codes reappear, indicating an ongoing problem.
Tools Required: OBD-II scanner.

4. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Visually inspect shock absorbers, struts, and bushings for wear and leaks.
3. Replace any damaged or worn suspension components.
Tools Required: Hydraulic jack, jack stands, wrench set.

5. Brake System Assessment

Sub-steps:
1. Inspect brake pads and rotors for wear; replace if necessary.
2. Check brake fluid level and condition; replace fluid if contaminated.
3. Test the operation of the ABS (Anti-lock Braking System) to ensure it engages correctly.
Tools Required: Brake pad gauge, brake fluid tester, wrench set.
