Automatic Stability Control (ASC)
OPERATIONThe slip control module (ASC) is integrated with the anti-lock brake (ABS) control unit. It operates in conjunction with digital motor electronic (DME) and electronic throttle control (EML).
The peripheral speeds of the wheels are monitored by the wheel sensors. An excessive speed difference between the driven and non-driven (idle) wheels is detected as wheel slip. Consequently, the EML control unit is instructed to reduce the throttle opening. If excessively high wheel slip still occurs, the DME control unit is instructed to shift the ignition timing in the retard direction. The ignition and the injection can be temporarily switched off as a further measure.
