CAN COMMUNICATION SYSTEM GENERAL


  1. OUTLINE


    1. The Controller Area Network (CAN) uses 2 different types of CAN buses:


      • The CAN V bus is a HS-CAN bus that operates at 500 kbps.

      • The CAN sub bus 1 is an MS-CAN bus that operates at 250 kbps.

    2. Each CAN bus has 2 terminating resistors which are necessary for accurate judgment of communication.

    3. The terminating resistors for each bus are located as shown in the following table.

      Speed Communication Bus Terminating Resistor Location
      High-speed (HS-CAN) CAN V Bus

      • ECM

      • Combination Meter Assembly
      Middle-speed (MS-CAN) CAN Sub Bus 1

      • Main Body ECU (Multiplex Network Body ECU)

      • ST-Plug

    4. The main body ECU (multiplex network body ECU) has a gateway function and is used to transmit data between the CAN V bus and the CAN sub bus 1.

  2. MAJOR DIFFERENCE


    1. The new models have been modified from the previous models as shown below:


      1. The separate type yawrate sensor has been discontinued.
