System Outline

Multiplex communication system (CAN) uses a serial communication protocol and communicates with a differential voltage.
In this network system, TERMINALS CANH and CANL are used for communication between the ECUs and sensors, and
excellent data communication speed and communication error detecting facility are provided.

This system is working for the following systems:

∗ ABS (w/ VSC)
∗ TRAC
∗ VSC
