CAN COMMUNICATION SYSTEM(for LHD) SYSTEM DIAGRAM


  1. w/ Network Gateway ECU

    Tech Tips


    • The master cylinder solenoid (skid control ECU) stores steering sensor and yaw rate sensor assembly DTCs and performs DTC communication by receiving information from the steering sensor and yaw rate sensor assembly.

    • The ECM uses the CAN communication system to perform DTC communication instead of the conventional communication line (SIL).
