System Outline
The CAN has two lines which operate as a pair and which communicate using operating voltage. CAN has excellent data speed and error detecting capacity. It consists of vehicle control systems such as gateway ECU, data link connector 3, 4WD control ECU, airbag sensor assembly center, distance control ECU, engine control module, power steering ECU, seat belt control ECU, skid control ECU with actuator, steering sensor and yaw rate sensor. The gateway ECU has communication circuits which correspond with the different types of communication data. Different types of communication data can then be shared among communication parts after it goes through gateway ECU.
