OUTLINE
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.
The HS-CAN consists of the V bus, the power management bus, multi-media bus* and diag bus*.
The CAN has 2 terminating resistors which are necessary for accurate judgment of communication on the main bus.
The terminating resistors for the V bus are located in the ECM and the combination meter assembly.
The terminating resistors for the power management bus are located in the ECM and the power management control ECU.
The terminating resistor for the multi-media bus* is located in the central gateway ECU (network gateway ECU).
The terminating resistor for the diag bus* is located in the central gateway ECU (network gateway ECU).
