Sliding Door Open/Close Switch Operation (Fully Closed To Fully Open 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 sliding door open/close switch is pressed, sliding door control unit terminal 2 receives the signal.
The sliding door control unit checks the automatic transaxle select lever (A/T device) position through terminal 18, vehicle speed through terminal 7 and battery voltage
For automatic sliding door LH, fuel lid door status is checked through sliding door control unit terminal 13
When the sliding door control unit receives the signal, if the auto sliding door operating enable conditions are met, including automatic door main switch in the ON position, doors in the unlock position and the child lock switch in the OFF position, it sends the unlock signal to the sliding door latch control unit.
When the sliding door latch control unit receives the signal, it supplies voltage from terminal 10 to operate the release actuator and unlatches the door lock.
The sliding door control unit supplies power from terminal 33 and supplies power from terminal 34 to the magnetic clutch to operate the sliding door motor and slide the sliding door in the open direction. (At this time, it also executes speed control, input reverse, and overload reverse control.)
When the sliding door is opened to the full-open position, the full-open position is detected by the encoder, and the sliding door control unit switches the sliding door motor OFF and controls the magnetic clutch ON --> half clutch --> OFF.
The sliding door is mechanically held in the fully open position by the checker.
