Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Tire Inspection and Replacement

Inspect Tires:
- Check each tire for uneven wear, proper tread depth (minimum 2/32"), and pressure (recommended PSI).
Replace Tires (if needed):
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts using a socket set and take off the tires.
- Install new tires, ensuring they are correctly seated on the rim.
- Torque the lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).

3. Traction Control System Check

Inspect Sensors:
- Locate the wheel speed sensors and visually inspect for damage or disconnection.
- Use a multimeter to test the sensor resistance; replace if faulty.
Reset Traction Control:
- Reconnect the battery and perform a reset of the traction control system using the OBD-II scanner.

4. Drivetrain and Suspension Inspection

Examine Drivetrain:
- Inspect the transfer case and differential for leaks or unusual noises during operation.
- Test fluid levels and condition; replace if contaminated.
Suspension Components:
- Check control arms, bushings, and struts for wear or damage. Replace any damaged parts.
