Automatic Transmission Remains in "P" Position
If you receive customer reports in the above model vehicles that the vehicle cannot be released from the "P" position despite Direct Select lever actuation, this can be due to a missing CAN signal from either the ESP or the steering column switch/control module.
When possible always start by processing any fault/event codes as per the test steps in Star Diagnosis and repair accordingly. When the situation requires that the vehicle must be moved, the "N" position can often be selected using SDS with SW version 8/05 or later. In such cases, using Star Diagnosis after entering all of the necessary vehicle information, please follow the path: Control units � Drive � ISM � Actuations � Move Transmission into Neutral position. Then follow the guided steps after observing the safety precautions listed in Star Diagnosis.
If the above steps fail to release the vehicle from position "P", MBUSA has introduced a new Special Tool, (W164 589 03 63 00 Free Wheeling Adapter), which will allow the vehicle to be easily moved when the transmission is locked in park.
If it becomes necessary to install the Free Wheeling Adapter in order to aid with vehicle recovery or to move a vehicle which cannot be disengaged from position "P", please perform the following steps.
1. Raise vehicle (on lift or using vehicle jack) and remove either the left or right rear wheel.
2. Install the Free Wheeling Adapter to the rear axle of the vehicle with the five (5) supplied Allen screws and tighten to a torque of 80 Nm (Figures 1 and 2).
3. Mount the original vehicle wheel to the Free Wheeling Adapter using the original wheel bolts and torque to 80 Nm (Figure 3).
4. With the Free Wheeling Adapter installed the vehicle can now be rolled to a desired location or onto a flatbed vehicle transporter without any difficulty.
Warning:
- The Free Wheeling Adapter is only for rolling the vehicle into a service bay or onto a flatbed transporter. It is not intended to be used for towing or driving and has a maximum speed rating of 5 Km/h or 3 mph.
- While the Free Wheeling Adapter is installed on the vehicle, the vehicle must be secured with the parking brake and wheel chocks to prevent it from rolling away unintentionally.
- When installing the Free Wheeling Adapter onto the vehicle it is important to always set the vehicle ride height to its maximum level using the vehicle level control switch, otherwise body to tire interference may occur.
