投诉

    The selector lever position P cannot be engaged by pressing the selector lever. It is not possible to shift to N. The vehicle cannot be moved.

原因

    1. Due to a lack of CAN signals from the ESP control unit or steering column switch module/control the conditions for disengaging selector lever position "P" are not fulfilled.

    2. Model series 221 with diesel engine OM642 in particular may be affected by a routing problem with the engine control unit.

补救

    Re 1.) Note: If possible, perform the test steps stored in Star Diagnosis on site. If one or more of the following event codes are current

    -P1923/1924/1925/1944/1945/1946/1947/1948/1952/1958/1959- (but no fault codes that indicate an internal malfunction), selector lever position "P" can be disengaged with the following setting in Star Diagnosis as an immediate measure to move the vehicle:

    - Access via Control units - Powerplant

    - Menu "ISM actuations" (Intelligent Servo Module)

    - Menu item "Move transmission into Neutral position"

    Then remedy the cause of the missing CAN signals.

    If unsuccessful, the vehicle can be made maneuverable as follows:

    Note: To prevent damage to the body, the vehicle must be at a ready-to-drive level.

    Mount the special tool "Freewheel mechanism" to one of the wheels on the

    rear axle between the wheel hub and wheel.

    Tightening torque, rim to freewheel mechanism 80 Nm

    Tightening torque, freewheel mechanism to rim 80 Nm

    IMPORTANT: With the freewheel mechanism fitted, the vehicle should be maneuvered by hand only. (max. 5 km/h or 3 mph)

    Driving or towing is not permissible.

    Re. 2.) Flashing of engine control unit with DAS DVD 01/08 or higher
