The ABS control module monitors the electrical signals generated by the ABS wheel speed sensors to determine how fast the wheels are slowing down during braking. If the ABS control module determines that a wheel is slowing too rapidly, it intervenes by modulating the brake pressure to that wheel; this prevents the wheel from locking up. A wheel that is locked up or not rotating has lost traction and cannot be steered. The ABS control module continuously performs diagnostic self-checks.

An anti-lock brake system (ABS) wheel speed sensor measures the speed of each wheel. Each wheel usually has one sensor, but some vehicles have one sensor for both rear wheels. The ABS wheel speed sensor utilizes a stationary electrical sensor that is located in close proximity to the rotating area of the wheel or axle; this electrical sensor generates an analog signal that corresponds to the wheel's actual speed.

  • The ABS control module may fail causing the ABS light to illuminate. Then you must carry out a scan test of ABS Electronic Control Unit (ECU) memory using a diagnostic scantool connected to the Data Link Connector (DLC) of the car. After that you can replace damaged pieces and erase ABS ECU from internal faults & reset ABS ECU. No more ABS warning messages on the dash board!

    The stability control system is typically triggered by the abs system/connector sensor on your wheel hub bearing. If you haven't replaced your hub bearings on the front you may have one going bad. Cheap fix for a diy.

    Whenever this warning or any other stays on in the dash it is indicating that the systems control module has detected a fault, it then disables the system as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)
