Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and set the parking brake.
  • Disconnect the battery to avoid any electrical issues.
2. Scan for Codes
  • Use an OBD-II scanner to read any stored error codes.
  • Note any codes related to the traction control system and address them accordingly.
3. Inspect Wheel Speed Sensors
  • Locate the wheel speed sensors on each wheel hub.
  • Remove any dirt or debris using a clean cloth.
  • Check the wiring for frays or disconnections.
  • If a sensor is damaged, replace it with a new one.
4. Verify Brake System Integrity
  • Inspect the brake fluid reservoir and ensure it is filled to the recommended level.
  • Look for any leaks in the brake lines or around the brake calipers.
  • If leaks are found, replace the damaged components and refill the brake fluid as necessary.
5. Check ABS Functionality
  • Perform a brake system self-test by applying the brakes and observing if the ABS activates correctly.
  • If the ABS is malfunctioning, inspect the ABS module and wiring for issues.
6. Tire Inspection and Adjustment
  • Check each tire for proper inflation according to the manufacturer’s specifications.
  • Inspect for uneven tire wear; if present, rotate or replace tires as needed.
