Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Sub-step 1: Inspect tires visually for uneven wear or damage.
- Tools: Tire tread depth gauge.
Sub-step 2: Measure tread depth. Replace tires if they are below the legal limit (typically 2/32 inches) or show uneven wear.
- Parts: New tires (matched to OEM specifications).

3. Check Tire Pressure

Sub-step 1: Use a tire pressure gauge to check each tire's pressure.
Sub-step 2: Inflate or deflate tires to the recommended pressure found on the driver's door jamb.

4. Traction Control System Check

Sub-step 1: Use a diagnostic tool to scan for error codes related to the traction control system.
Sub-step 2: Clear any fault codes and perform a test drive to see if the issue persists.

5. Brake System Inspection

Sub-step 1: Inspect ABS sensors and wiring for any damage or disconnection.
Sub-step 2: Replace any faulty ABS sensors with OEM parts.
