Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, jack stands, wheel chocks, multimeter.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove all four wheel covers (if applicable) using a wheel removal tool.
2. Inspect each tire for wear, damage, or uneven tread depth.
3. Measure tire pressure and inflate to the recommended PSI if low.
4. Replace any damaged tires with new ones that meet manufacturer specifications.
5. Balance and align the tires after replacement.

3. Traction Control System Check

Sub-steps:
1. Reconnect the battery and use the OBD-II scanner to check for traction control system codes.
2. Clear any codes and conduct a self-test of the traction control system.
3. If codes reappear, follow service manual procedures to diagnose the specific issue.

4. Drivetrain Inspection and Repair

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect the driveshaft for any signs of wear or damage; replace if necessary.
3. Check the differential fluid level and condition; replace with manufacturer-recommended fluid if low or dirty.
4. Examine the wheel speed sensors for dirt or damage; clean or replace if necessary.

5. Brake System Inspection

Sub-steps:
1. Remove the front and rear wheels to access the brake components.
2. Inspect brake pads and rotors for wear; replace if below manufacturer specifications.
3. Check for any sticking calipers; clean and lubricate as needed.
