Monitor Description

The Controller Area Network (CAN) is a serial data communication system for real-time application. It is a multiplex communication system designed for on-vehicle use that provides a superior communication speed of 500 kbps and a capability to detect malfunctions.

The hybrid vehicle control ECU sends and receives data to and from ECUs connected to the V1 bus and V2 bus. If a communication error occurs between the hybrid vehicle control ECU and one of these ECUs, the hybrid vehicle control ECU stores a DTC.
