E88 Complete Vehicle
Vehicle Systems Network
The vehicle electrical system on the E88 is very similar to that on the E93.
The E93/E88 vehicle electrical systems differ only slightly by the omission or addition
of some control modules.
Changes to the K-CAN
The convertible Top module (CVM) controls the convertible Top operation.
The High-Beam Assistant is not offered on the E88, so the control unit for the High-
Beam Assistant (FLA) has been omitted.
Changes to the MOST
SBX High is offered along with the Telematics Control Unit (TCU). SBX High permits the
connection of external devices such as mobile phones from various manufacturers and
USB devices (MP3 players, USB sticks or iPods).
Changes to PT-CAN
The longitudinal dynamics management (LDM) and Active Cruise Control (ACC)
functions are not offered in the E88.
Note: As on all current new BMW models D-CAN is incorporated to the bus
system instead of D-bus to enhance communication on this line and
comply with OBD regulations.
