Wireless Control Does Not Operate

ONLY WIRELESS CONTROL FUNCTION DOES NOT OPERATE (PREPARE NEW OR NORMAL TRANSMITTER OF THE SAME TYPE VEHICLE)

CIRCUIT DESCRIPTION
The door control receiver receives a signal from the transmitter and sends this signal to the body ECU. Then, the body ECU controls operation of the door locks except the back door lock in response to this signal, while the body ECU sends a signal to the back door ECU at the same time. Receiving this signal, the back door ECU controls operation of the back door lock. Also, the back door ECU causes the back window to open, receiving a signal from the transmitter via the body ECU.
