DESCRIPTION
The door control receiver receives a signal from the transmitter and sends this signal to the multiplex network body ECU. Then, the multiplex network body ECU controls operation of the door locks and power windows.
Then, the power slide door ECU causes the power slide door to open or close when it receives a signal from the transmitter via the door control receiver and multiplex network body ECU. Also, the power back door ECU causes the power back door to open or close when it receives a signal from the transmitter via the door control receiver and multiplex network body ECU.
