Circuit Description
WARNING: This page is about a different car, the 2004 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
The door control receiver receives signals from the transmitter and sends these signals to the multiplex network body ECU. The multiplex network body ECU then controls all the doors by sending LOCK/UNLOCK signals to each door lock actuator, buzzer signals to the wireless door lock buzzer and headlamp/taillamp and hazard warning signals to the turn signal flasher relay.
