ICM Control Unit
NOTE:
If the ICM control unit needs to be replaced, the repair instructions must be observed without fail.
For example, the vehicle battery must be disconnected before removing the control unit and reconnected following the installation. This is the only way to ensure synchronized restarting of the control unit assembly.

NOTE:
The ICM control unit must not be exposed to strong vibrations. The integrated sensor system will be destroyed if the housing is struck by hard objects, or if the control unit is dropped. The control unit must not be installed in the vehicle in this case.
NOTE:
Only screws and spacer sleeves that are in perfect condition may be used to mount the ICM control unit. Deformed or damaged fixing elements must not be used.
The mounting screws in the reamed holes must be tightened first, followed by the other two screws. The tightening torque specified in the repair instructions must be observed without fail.
A check must then be carried out to make sure the control unit is mounted securely and free of play.

NOTE:
Once the new ICM control unit has been installed, it must be started up with the assistance of the diagnostic system. To do this, the following steps must be carried out (depending on the equipment specification):
- Calibration of the sensors integrated into the ICM
- Calibration of the ride-height sensors
- Initialization of the Integral Active Steering.
