OPERATION
The slip control module (ASC) is integrated with the anti-lock brake (ABS) control unit. It operates in conjunction with digital motor electronic (DME) and the auxiliary throttle control module (ADS ll).
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 ADS ll control unit is instructed to reduce engine power. 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.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
