- Summary
- MIL on. DTCs for the cam actuators are stored in ECM memory. After the activation of the cam actuator to change to the other cam profile, the pin of the actuator is pushed back in by the cam. This is confirmed by a voltage impulse, which is registered by the engine control unit and confirms the operation. If this does not happen, or not at the right time, a DTC "implausible signal" is saved in ECM memory. Check the distance of the pin tip of the cam actuator for valve lift system to the camshaft when it is not operated with a gauge. The measurement of the tip to the basic camshaft circle outside of the groove must be taken. If this measurement is 0.9mm, the actuator 06E103697J must be installed. The actuator 06E103697J must only be used, if the measurement is 0.9mm or bigger.
