Crankshaft Position Timing Ring: Service Precautions

Sensor wheel adaptation must be carried out after replacing a DME control unit or increment wheel. If only the increment wheel is replaced, the sensor-wheel adaptation must first be deleted (disconnect control unit from power supply for 5 minutes) Sensor wheel adaptation is implemented automatically as soon as the engine is operated in overrun condition for at least 10 seconds. Adjustments -- Refer to Sensor-Wheel Adaptation.
