Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and securely supported on jack stands.
  • Disconnect the battery to prevent electrical shock.
2. Inspect Wheel Speed Sensors
  • Remove the wheel on the affected corner(s) to access the wheel speed sensors.
  • Clean the sensors and surrounding areas to remove any debris.
  • Check wiring for frays or disconnections; repair or replace as necessary.
3. Check Brake Fluid and System
  • Inspect the brake fluid reservoir; top off with the recommended fluid if low.
  • Examine brake lines for leaks or damage; replace any damaged sections.
  • Ensure proper operation of brake components and ABS module.
4. Test ABS Control Module
  • Reconnect the battery and turn the ignition to the "ON" position (do not start the vehicle).
  • Use the OBD-II scanner to check for ABS control module communication and error codes.
  • If issues persist, consider replacing the ABS control module as per manufacturer's specifications.
5. Final Assembly
  • Reattach the wheel securely and torque lug nuts to the manufacturer's specifications.
  • Test drive the vehicle to ensure the stability control light does not reappear.
