The following differences between the electrical systems of the series production E7x vehicles compared to the E70/E71 M must be noted:
PT-CAN:
The S63 is exclusively equipped with the DME MSD85.1.
The control unit for active steering (AL) has been dropped as active steering is not offered for the E70/E71 M vehicles. However all other control units (DSC, ICM, QMVH, VDM and ARS) are installed because E70 M and E71 M are equipped with Adaptive Drive, Dynamic Performance Control and Integrated Electronic Height Control as standard equipment.
K-CAN:
The PDC function has been integrated in the junction box as on F01.
The control unit for the optional auxiliary heating control for the 3rd row of seats (ZHS3R) has been dropped as this option is not offered for the E70 M.
TRSVC top rear side view camera (option) is installed for the first time on US E7x vehicles
MOST:
As from 10/09 the CIC is also installed in the series production E70 and E71 vehicles and there is no difference in the vehicle electrical system of the E70/E71 M vehicles compared to the series production E71 models.
CIC Basic uses a smaller screen and refers to the CIC option without Navigation
The functions of the CCC/MASK/CHAMP, IBOC, SDARS are all integrated in the CIC. These control units are therefore no longer installed in the vehicle.
