HINT: This ECU is integrated with the multiplex communication system.

MULTIPLEX COMMUNICATION SYSTEM (BEAN)
Body Electronics Area Network (BEAN) communication line is used for body, meters and air-conditioning controls. Since the line is loop-shaped, the communication can be kept by the line that is not open even if a part of the line becomes open for some reasons. In case that the line becomes short (bus-down) for some reasons, however, all the BEAN communication will be impossible and some DTC will be output.
