Technical Description (Comment)

When the KOS & OSS-ECU certification result is different from the engine status after the completion of engine starting permission communication, KOS & OSS-ECU determines that a problem has occurred, and stores DTC B1A28. At the same time, KOS & OSS-ECU displays the immobilizer certification system inspection warning to the combination meter.
