Learning in Selection Range Sensor Not Possible After EHS Replacement





In the above model vehicles, after removing/installing the electrohydraulic control unit (EHS), learning in the selection range sensor is not possible if the retaining bolt of the detent plate was not inserted into the plastic bracket of the selector range valve (Figure 1). During initial start-up with Star Diagnosis, the message "The prerequisites are not fulfilled or the peripherals are not operational" is displayed, although the shift rod has been correctly adjusted. To resolve, remove/reinstall EHS being sure to insert bolt into bracket on valve and proceed to teach the sensor using Star Diagnosis.
