General Information

Component Location


















General Description

To make system be more efficient, Body Control Module (hereinafter referred to BCM) applies CAN (Controller Area Network) communication system. CAN is a kind of communication system which can make related component share system information with just two line instead of complex individual signal line. It consists of related component and CAN BUS which consists of CAN_high line and CAN_low line. Each component can send and receive information by binary signal via CAN BUS. The related components for BCM are IPM, ADM, DDM, FAM, RAM, IMS and cluster module.

DTC Description

To make communication be more accurate, every signal via CAN BUS contains error flame. Each component counts error and if accumulative error count in one node is above specified value, the ECM sets DTC B1603 and pertinent component is electronically separated.
