If the ABS and Traction Control light came on after you got your car serviced, something may have gone wrong during your brake job. Here are some of the issues that could cause your ABS and Traction Control light to come on after a brake job:
  • Contaminated
    brake fluid
  • The wheel speed sensor was knocked loose during the service
  • The sensor connector wires were not reconnected to their original position
  • Loose battery terminals
