Component Location





General Description

All 6 units which consists of the Body Electrical Control System are linked by MM CAN line.
They are IPM(Intelligent integrated Platform Module), CLU(Cluster), HU(Head Unit), Monitor, RRC(Rear Remote Control), AMP(Amplifier).
MM(MultiMedia) CAN (Controller Area Network) : MM(MultiMedia) CAN is serial bus communication type which links not only communication system but also control units each other.
