CAN Communication Line

CAN COMMUNICATION LINE

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 a 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.

TCS COMMUNICATION LINE

Description
This CAN communication line is used to control the smooth engine operation during the TCS operation. Pulse signals are exchanged between ECM and ABS actuator and electric unit (control unit).

Be sure to erase the malfunction information such as DTC not only for ABS actuator and electric unit (control unit) but also for ECM after TCS related repair.
