Pinpoint Test F : The Roof Opening Panel Shield Does Not Open Or Close: 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

The roof opening panel primary motor receives voltage from the accessory delay relay when the ignition is in the ACC or RUN position. The primary motor communicates ignition state to the roof opening panel shield motor along the K-Bus communication circuit. The overhead console switch supplies signals to the roof opening panel shield motor to operate the roof opening panel shield. A failure in the power circuit, ground circuit, switch signal circuit or K-Bus circuit, an internal failure of the switch or shield motor all cause the roof opening panel shield to become inoperative.

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.
