CAN COMMUNICATION SYSTEM


  1. OUTLINE


    1. The CAN V bus, CAN sub bus 11, and CAN sub bus 15 are HS-CAN buses that operate at 500 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.

      High-speed (HS-CAN) CAN V Bus

      • ECM

      • Combination Meter Assembly
      CAN Sub Bus 11

      • Hybrid Vehicle Control ECU Assembly

      • No. 1 CAN Junction Connector
      CAN Sub Bus 15

      • ECM

      • Hybrid Vehicle Control ECU Assembly

    4. The hybrid vehicle control ECU has a gateway function and is used to transmit data between the CAN V bus and the CAN sub bus 11.

    5. The hybrid vehicle control ECU has a gateway function and is used to transmit data between the CAN V bus and the CAN sub bus 15.
