Remote Control Automatic Back Door Function (Vehicles With Automatic Back Door System)

WARNING: This page is about a different car, the 2004 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.

Switching from all closed to all open

When a button on the keyfob is operated, the signal is sent from the keyfob and received by the remote keyless entry receiver.
The received signal is sent to the BCM and compared with the registered ID number.
If the ID number matches, the BCM uses communication to send the back door open signal to the back door control unit.
When the back door control unit receives the back door open signal, if the remote control automatic back door operation enable conditions are met, the warning chime is sounded and the back door unlock signal is sent to the back door latch using communication.
When the back door latch receives the back door unlock signal, it operates the release actuator and releases to back door latch.
The back door control unit operates the back door motor to open the back door. (At this time, speed control, input reverse, and overload reverse control are executed.)
When the back door is opened to the fully open position, the full-open position is detected with the rotation sensor, the back door motor is stopped.
The door held by the back door stays at the full open position.

Full open To full closed operation

When a button of the keyfob is operated, the signal is sent from the keyfob and received by the remote keyless entry receiver.
The received signal is sent to the BCM and compared with the registered ID number.
If the ID number matches, the BCM uses communication to send the back door close request signal to the back door control unit.
When the back door control unit receives the back door close request signal, if the remote control automatic back door operation enable conditions are met, the warning chime is sounded and the back door motor begins closing the back door.
The back door control unit operates the magnetic clutch and the back door motor to close the back door. (At this time, the back door control unit executes speed control, input reverse, and overload reverse control.)
When the back door comes to the half-latch state, the back door latch detects the half-latch state through half-latch switch operation. The back door latch latches the back door.
