CAN COMMUNICATION SYSTEM > GENERAL



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 V1 bus, V2 bus and the power management bus.

  3. 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.

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

  5. The terminating resistors for the V1 bus are located in the ECM and the combination meter assembly.

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

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

  8. The terminating resistors for the MS bus are located in the junction connector and the main body ECU (multiplex network body ECU).
