Principles of Operation
PRINCIPLES OF OPERATIONRoof Opening Panel Shade
The roof opening panel assembly uses an integrated motor and module to operate the roof opening panel shades. The roof opening panel shade can be opened or closed by the shade control switch. Pressing the shade control switch in either the OPEN or CLOSE position supplies a ground to the roof opening panel shade motor/module. The shade panels are equipped with express open and close features. A short press of the shade control switch will cause the shade panel to express open to the full open position or close to the safety stop position. The shade will not close when the roof opening panel is open.
NOTE: Any glass opening operation will first fully open the shade panels. Before the shade panels may be closed, the glass panel must be fully closed.
The roof opening panel shade motor must be initialized when one of the following occurs:
- The replacement or removal of the drive system
- Excessive false stalls are encountered
- The shade(s) are removed or replaced
- The shade motor becomes de-initialized (will stutter step open)
The roof opening sliding glass panel motor must be initialized when one of the following occur:
- The replacement or removal of the drive system
- Excessive false stalls are encountered
- The sliding glass panel is removed
- The sliding glass motor becomes de-initialized (will stutter step open and have no express operation)
Roof Opening Panel
The roof opening panel assembly uses an integrated motor and module to operate the roof opening panel sliding glass. The roof opening panel sliding glass can be opened, closed or tilted by the roof opening panel control switch. Pressing the open, close or tilt switch grounds those inputs to the glass panel motor/module. Momentarily pressing the tilt switch will cause the glass panel to express open to the VENT position if the glass panel is closed or cause the glass panel to close to the VENT position if the glass panel is in the slide open range and the tilt switch is pressed and held. Pressing and holding the control switch forward will close the glass panel (the safety stop position is skipped in manual mode). The glass panel has express open and close features that are activated when the switch is momentarily pressed to the double detent OPEN or CLOSE positions. Express open operation will first open the glass panel to the comfort stop position. Pressing the switch again will cause the glass to move to the full open position. Pressing the switch again will cause the glass to move to the full open position. Express close operation will move the glass panel to the full closed position.
NOTE: Any glass opening operation will first fully open the shade panels. Before the shade panels may be closed, the glass panel must be fully closed.
The shade motor and sliding glass panel motor have 3 thermal operating modes:
- Full function: In their fully functioning state, the motors allow all normal operations of the shades and glass.
- Reduced function: If either motor begins to overheat, it will enter a reduced function mode. No express operation is possible and it will allow open or close motion in steps of 50.8 mm (2 in).
- No function: Excessive heating causes no function mode. The motor will not operate in the close direction, but will open in steps of 50.8 mm (2 in). Once the open position is reached, the motor shuts itself down until it is sufficiently cooled.
Global Open - MKX only
When the unlock button of the remote keyless entry (RKE) transmitter is held for 2 seconds the global open activates. The smart junction box (SJB) sends a signal to activate the one-touch open operation of the roof opening panel. The global open feature does not operate if the delay accessory is active.
