CAN COMMUNICATION SYSTEM GENERAL


  1. OUTLINE


    1. The Controller Area Network (CAN) is a serial data communication network for real time application. It is a multiplex communication network equipped in a vehicle, and has communication speeds of 500 kbps (HS-CAN), and the ability to detect malfunctions.

    2. The HS-CAN consists of the V1 bus, V2 bus and power management bus.

    3. The MS-CAN consists of the parking assist bus.

    4. The power management control ECU has a gateway function and is used to transmit data between the power management bus, V1 bus and V2 bus.

    5. CAN has 2 terminating resistors which are necessary for accurate judgment of communication on the main bus.

    6. The terminating resistors for the V1 bus are located in the ECM and the plugin charge control ECU assembly.

    7. The terminating resistors for the V2 bus are located in the power management control ECU and the junction connector.

    8. The terminating resistors for the power management bus are located in the ECM and the power management control ECU.

    9. The terminating resistors for the parking assist bus are located in the driving support ECU assembly and the millimeter wave radar sensor.
