CAN COMMUNICATION SYSTEM


  1. OUTLINE


    1. The Controller Area Network (CAN) is a serial data communication network for real time application. It is a multiplex communication network to be 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 V bus, the power management bus*1 and the power train bus*2.

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

    4. The terminating resistors for the V bus are located in the ECM and the combination meter assembly.

    5. The terminating resistors for the power management bus*1 are located in the ECM and the power management control ECU*1.

    6. The terminating resistors for the power train bus*2 are located in the ECM and the engine stop and start ECU*2.
