System Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto each vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

Description
The IPDM E/R (intelligent power distribution module engine room) controls the
tail lamp relay based on inputs from the BCM over the CAN communication
lines. When the tail lamp relay is energized, power flows through fuses 46
and 47, located in the IPDM E/R. Power then flows to the ...
