ABS Control Module

The anti-lock brake system (ABS) control module operates the ABS system based on data received from its various sensors.

Symptoms of Wear or Failure of the ABS Control Module

  • Illumination of the ABS warning light
  • A failing ABS control module can turn on the ABS light and disable the traction and stability control systems (if equipped)
  • In some cases, the speedometer will stop working and the Check Engine Light will come on
  • A malfunctioning ABS control module can cause abnormal braking behavior when braking at low speeds

ABS Control Module Related Repair Advice

  • The ABS control module continuously performs diagnostic self-checks. If it finds a problem, it will shut down the system and illuminate a warning light.
  • On some vehicles, it will be necessary to flush the brake system with new fluid when replacing the ABS control module
  • On newer vehicles, the module may need to be "programmed" before the vehicle is driven

I own a Mazda 6 model 2005. and suddenly the check engine light came on along with the ABS light and the handbrake light and the AT (transmission) light all together. the car went bizerk. the speedometer and the milage stopped. it turned out to be the ABS control unit that did all that stuff. and unfortunaly i cannot fint neither a used part or a new part cause apparently the model 2005 was an experimental issue to repair some errors in the 2003 and 2004 models, and this comes from a guy who specializes in mazda 6 repairs. So if anyone plans to buy a mazda 6, get the 2006 model and above.
