ONLY BACK DOOR CAN NOT BE OPENED (UNLOCKED) (W/ POWER BACK DOOR)

CIRCUIT DESCRIPTION
The signal for manual locking/unlocking operation of the driver/passenger side door and the signal for locking/unlocking operation interlocked with the driver side door key cylinder are sent to the back door ECU from the body ECU using the BEAN. In response to these signals, the back door ECU causes the back door lock to switch to the lock/unlock position. The ON signal of the back door opener switch, which is output when the switch is pressed, is directly sent to the back door ECU. In response to this signal, the back door ECU causes the back door lock to switch to the open position.
