If the necessary data cannot be received from engine control module via CAN bus line during the engine starting certification with engine control module, OSS-ECU determines that a problem has occurred, and stores DTC B1731. At the same time, OSS-ECU displays the immobilizer certification system inspection warning screen to the multi information display of the combination meter.
