System Description: Notes

NOTE: The automatic back door system must be initialized by fully closing the back door anytime the battery power is lost to the back door control unit.

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-state.

Back door auto closure
When the back door is closed to the halfway state (half-latch) position, the motor automatically drives to rotate the latch lever and pull it in from half latched to full latched.
Power back door
With the back door closed, press the power liftgate switch or press the keyfob button, or pull the back door handle with the back door unlocked, the back door latch motor opens the locking plate and releases the latch. The back door motor then raises the door to the full open position.

With the back door fully open, press the power liftgate switch, keyfob 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.

At the onset of each power open or power close application, the hazard lamps will flash 3 times and the warning chime will sound 3 times lasting a total of 2 seconds.
