Remote Keyless Entry Operation (Fully Open --> Fully Closed Operation)

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

When the remote keyless entry button is pressed for at least 0.5 seconds, back door control unit terminal 21 receives the signal.
The back door control unit checks the automatic transaxle select lever (A/T device) position through terminal 18, vehicle speed through terminal 21 and battery voltage
When the back door control unit receives the signal, if the auto back door operating enable conditions are met, it sends a signal through terminal 6 and grounds terminal 9 to sound the warning chime, sends a signal to the BCM through terminal 4 to flash the hazard lamps and sends the unlock signal to the back door latch.
When the back door latch receives the signal, it supplies voltage from terminal 11 to operate the release actuator and releases the door lock.
The back door control unit supplies power to the magnetic clutch and the back door motor and moves the back door in the open direction. (At this time, it also executes speed control, input reverse, and overload reverse control.)
When the back door is opened to the full-open position, the full-open position is detected by the encoder, and the back door control unit switches the back door motor OFF and the magnetic clutch is pulsed and then turned OFF.
The back door is held in the fully open position by the gas stays.

When the remote keyless entry switch is pressed for at least 0.5 seconds, the back door control unit terminal 21 receives the signal.
The back door control units checks battery voltage.
When the back door control unit receives the signal, if the auto back door operating enable conditions are met, it sends a signal through terminal 6 and grounds terminal 9 to sound the warning chime and sends a signal to the BCM through terminal 4 to flash the hazard lamps.
The back door control unit supplies power to the magnetic clutch and the back door motor and move the back door in the close direction. (At this time, it also executes speed control, input reverse, and overload reverse control.)
When the back door reaches the half-latch state, the half-latch switch detects this and the signal is sent to the back door control unit terminal 22.
When the back door control unit receives the signal, it switches OFF the back door motor and the magnetic clutch.
When the cinch latch motor operates and the close switch detects this and the back door control unit terminal 14 receives the signal from back door latch terminal 5.
When the back door latch operates and full close is detected through terminal 14 of the back door control unit, the back door auto closure operation ends and the door is fully closed.
