  4. HEADUP DISPLAY (COMBINATION MIRROR METER ECU)


    1. General


      • The combination mirror meter ECU receives various types of signals from the combination meter sub-assembly via the AVC-LAN communication line. Based on the signals, various types of information are displayed on the windshield.

        The combination meter sub-assembly receives signals from the skid control ECU, driving support ECU, navigation ECU sub-assembly and air conditioning amplifier assembly via CAN communication.

      • Various types of information can be displayed on the windshield by pressing the headup display switch assembly (HUD main switch) on the instrument panel.
