Sonar Control Unit (With Around View Monitor): Description
WARNING: This page is about a different car, the 2016 Infiniti QX80. However, it is still accessible from the selected car via links, so may be relevant.
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 independently). In CAN communication, control units are connected with 2 communication lines (CAN - H, CAN - L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
