Solution

1. Tire Inspection

Check tire pressure: Use a tire pressure gauge to ensure all tires are inflated to the recommended PSI.
Inspect tread depth: Use a tread depth gauge or penny test to check for uneven wear.
Replace damaged tires: If any tire shows significant wear or damage, replace it with a matching specification tire.

2. Suspension and Alignment Check

Visual inspection: Check for worn or damaged suspension components such as shocks, struts, and bushings.
Perform alignment check: Use a wheel alignment machine to ensure the vehicle is aligned to manufacturer specifications.
Replace worn components: If any suspension parts are found to be worn, replace them as necessary.

3. Traction Control System Testing

Engage traction control: Drive the vehicle in a controlled environment to test the operation of the traction control system.
Check for error codes: Use an OBD-II scanner to identify any faults in the traction control system and address them accordingly.
