Sunroof / Moonroof: Description and Operation

Roof Opening Panel

The roof opening panel consists of the following:

- Concertina blinds
- Air deflector
- Trough assembly
- Roof opening panel glass
- Roof opening panel motor/module
- Roof opening panel shield
- Roof opening panel switch
- Roof opening panel drain hoses

The roof opening panel is an electronically operated panel that can be opened or closed by pressing a switch located on the overhead console. It also has one-touch open, one-touch close, one-touch vent open and one-touch vent close features.

When the roof opening panel is in the fully CLOSED position, pressing the roof opening panel control switch rearward to the second detent and then releasing it will activate the one-touch open feature. Pressing the roof opening panel control switch in either direction with the roof opening panel moving will cancel the one-touch open operation.

With the roof opening panel glass in any OPEN position except VENT, rocking the roof opening panel control switch forward and then releasing it will activate the one-touch close feature. Pressing the roof opening panel control switch in either direction with the roof opening panel moving will cancel the one-touch close operation and the motion will immediately stop. Near the end of the forward travel, the rear portion of the roof opening panel glass moves upward on 2 lifter arms. This allows a weather-tight seal when the roof opening panel glass is closed.

If an obstacle contacts the leading edge of the roof opening panel glass during one-touch close operation, the roof opening panel glass will reverse direction and open to approximately the mid position and stop. The operator cannot stop this open motion once it has begun.

If an obstacle contacts the rear edge of the roof opening panel glass during one-touch vent close operation, the roof opening panel glass will reverse direction to the vent OPEN position.

When the roof opening panel glass is in the fully CLOSED position, pressing the roof opening panel control switch forward and then releasing it will activate the one-touch vent feature. Pressing the roof opening panel control switch in either direction with the roof opening panel moving will cancel the one-touch vent operation. There is a one-touch vent close feature.


Global Open - MKZ Only

NOTE: The global open feature may be enabled/disabled via scan tool or in some cases modified by the customer following a procedure listed in the vehicle Owner's Literature. For a complete list of available programmable parameters, refer to the Module Configuration and Parameter Chart in Information Bus. Principles of Operation

NOTE: The Smart Junction Box (SJB) may also be identified as the Generic Electronic Module (GEM).

When the unlock button of the Remote Keyless Entry (RKE) is held for 2 seconds, the SJB sends a signal on the global open circuit, to both front door window motors and the roof opening panel motor, to open the windows. If the accessory delay relay is active, the global open feature will not operate.
