System Description: 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.
- This vehicle has two CAN communication. One is CAN communication, the other is Drivetrain CAN communication. ECM includes a gateway function and communicates signals between the CAN communication circuit and Drivetrain CAN communication circuit.
Drivetrain CAN communication circuit connects the following ECU:
- ECM
- TCM
- Sub electric oil pump inverter
- A/T shift selector
- Resistor
