General Description

All 13 units which consists of the Body Electrical Control System are linked by CAN* line.
They are IPM (Inter Panel Module), FAM (Front Area Module), PDM (Power Distribution Module), DDM (Drive Door Module), ADM (Assist Door Module), ECW (Electronic Control Wiper), CLU (Cluster), MFSW (Multi Function Switch), PSM (Power Seat Module), SCM (Steering Control Module), PTM (Power Trunk Lid Module), FBWS (Front Back Warning System), DATC (Dual Auto Temperature Control Module).
The steering wheel's Lock/Unlock state from ESCL (Electronic Steering Column Lock) and the related data to starting from EMS are sent to IPM by the serial communication line.
* CAN (Controller Area Network): CAN is serial bus communication type which links not only communication system but also control units each other.
*2 LIN (Local Interconnect Network): LIN is serial communication type which is used in electrical control system. (This is less expensive.)
