Solution

1. Tire Inspection and Replacement

Inspect the tires for tread depth using a tread depth gauge. Minimum tread depth should be 2/32 inch.
Replace tires if they are worn beyond the minimum depth or if uneven wear is present.
Align the wheels if uneven wear is detected.

2. Tire Pressure Adjustment

Check the tire pressure using a tire pressure gauge.
Inflate tires to the recommended PSI as listed on the driver's side door jamb.

3. Traction Control System Check

Connect an OBD-II scanner to the vehicle’s diagnostic port.
Read any error codes related to the traction control system.
Clear error codes and perform a test drive to see if they return.

4. Suspension Inspection and Repair

Visually inspect suspension components for any signs of wear or damage.
Replace any worn components, such as shocks or bushings, as necessary.
Retorque all suspension bolts to the manufacturer's specifications.

5. ABS System Verification

Inspect wheel speed sensors for dirt or damage.
Clean or replace sensors if necessary.
Test the ABS system operation by performing a controlled brake test.
