Solution

1. Tire Inspection and Replacement

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the recommended PSI.
Inspect Tread Depth: Measure tread depth using a tread depth gauge; replace tires if they are worn below the recommended level.
Alignment Check: If tires are unevenly worn, perform a wheel alignment.

2. Traction Control System Reset

Locate OBD-II Port: Find the OBD-II port under the dashboard on the driver's side.
Connect OBD-II Scanner: Use the scanner to read and clear any traction control error codes.
Test Drive: After clearing codes, take the vehicle for a test drive to confirm the traction control system is functioning properly.

3. Drivetrain Inspection

Visual Inspection: Check for leaks or damage in the transmission and differential.
Fluid Levels: Inspect and top off transmission and differential fluids as necessary.
Test the Differential: If slipping continues, have a technician check the differential for proper operation.
