Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, jack and jack stands, socket set, torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during inspections.

2. Inspect and Replace Tires

Sub-steps:
1. Jack up the vehicle and remove the wheel covers if present.
2. Measure the tread depth using a tread depth gauge; replace tires if tread is below 2/32 inch.
3. Inspect for sidewall damage or punctures.
4. If tires need replacement, install new ones ensuring they match the specifications (size and type) recommended by the manufacturer.
5. Torque the lug nuts to the manufacturer's specifications (typically 80-100 lb-ft).

3. Check and Adjust Tire Pressure

Sub-steps:
1. Use the tire pressure gauge to check each tire's pressure.
2. Inflate or deflate tires to match the recommended pressure found in the driver's side door jamb or owner's manual.
3. Recheck pressure after adjustments.

4. Inspect Traction Control System

Sub-steps:
1. Reconnect the battery and use the OBD-II scanner to check for DTCs related to the traction control system.
2. Inspect wheel speed sensors for damage or disconnection and clean or replace as necessary.
3. If no faults are found, perform a reset of the traction control system via the scanner.

5. Examine Suspension Components

Sub-steps:
1. Visually inspect struts, shocks, and bushings for signs of wear or damage.
2. Replace any worn or damaged components, ensuring proper alignment afterward.
3. Recheck suspension alignment and adjust as necessary to manufacturer specifications.
