Pinpoint Test H : The One-Touch Feature Is Inoperative: Notes

WARNING: This page is about a different car, the 2015 Lincoln MKZ. However, it is still accessible from the selected car via links, so may be relevant.

Refer to ROOF OPENING PANEL for schematic and connector information.

The roof opening panel must be initialized when repairs are carried out on any part of the roof opening panel system or when the roof opening panel motors, glass, assembly, or air deflector has been removed or replaced for any reason. REFER to: Power Roof Opening Panel Initialization - Vehicles With: Panoramic Roof Opening Panel.

Normal Operation and Fault Conditions

With the ignition switch in the ON position touching the roof opening panel control switch open symbol will activate the one-touch open feature, first opening the roof opening panel shield if it is closed, then opening the roof opening panel glass. When in one-touch open mode (except vent), touching any roof opening panel control switch symbols will cancel the one-touch operation and place the glass at that specific position. The roof opening panel switch has separate roof opening panel shield open and close positions to operate the shield independent from the glass. The shield will not close if the glass is in the open position. With the roof opening panel glass in any open position, touching the roof opening panel control switch close symbol will activate the one-touch close feature. When in one-touch close mode, touching any roof opening panel control switch symbol will cancel the one-touch operation and place the glass at that specific position. In vent one-touch open or close mode the one-touch operation will not manually cancel.

If an obstacle is between the glass and the frame when the roof opening panel is closing the contacts inside the anti-pinch switch will touch and signal the motors to reverse direction. Note that the anti-pinch signal is ignored by the motors at predetermined position near the point where the glass begins to move down to seal allowing an air tight seal to the frame. If there is any issue with the pinch switch that causes bounce back and remains for more than 30 seconds the motor will ignore the anti-pinch switch, and after a key cycle will operate the glass by pressing and holding the control switch (manual mode) to open or close.

When the roof opening panel glass is in the closed position, touching the roof opening panel control switch vent symbol will activate the one-touch vent open feature. When the roof opening panel glass is in the vent position, touching the roof opening panel control switch close symbol will activate the one-touch vent close feature.

NOTE: There are 2 motors that provide the movement of the roof opening panel glass. Both motors are connected to both sides of the glass and operate simultaneously when opening or closing the roof opening panel. The RH (passenger side) motor is the primary motor and the LH (driver side) motor is the secondary motor. The primary motor has 9 circuits in a single connector and the secondary motor has 4 circuits in a single connector. The shield motor is the center motor. All 3 motors have a similar connector.

NOTE: The anti-pinch switch connector is located under the parcel shelf on the LH side near the d-pillar trim panel. The anti-pinch switch wires run up the pillar.
