System Description: Notes

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.

The automatic back door system consists of a one piece unit that combines the back door control unit along with the back door motor, back door clutch and the back door encoder. The back door latch contains a lock function that can control the two functions of automatic back door latch closure and electrical opener with a single motor when you close the back door to the halfway-sate.

Back door auto closure
When the back door is closed to the half-way state (half-latch) position, the motor drives to rotate the latch lever and pull it in from half latched to full latched and automatically close the door.
Power back door
With the back door closed, if you press the automatic door main switch or press the remote keyless entry button, or pull the back door handle with the back door unlocked, the back door latch motor drives the open the locking plate and release the latch. The back door motor then raises the door to the full open position.

With the back door open, if you press the automatic door main switch, remote keyless entry button or the back door close switch, the back door motor closes the door to the half-latch state. The back door latch motor then drives the latch to the full close position.

On an open or close signal, the hazard lamps will flash 3 times and the warning chime will sound 3 dings lasting a total of 2 seconds.
