Circuit Description

The multiplex network body ECU senses, by the un-lock warning switch, that the ignition key is in the key cylinder. Because of this, the multiplex network body ECU will unlock all the doors immediately after locking them if a door has been locked while the key is in the ignition key cylinder.
