Glass, Frames and Mechanisms - System Operation and Component Description

Front Controls Interface Module (FCIM)

The FCIM contains the rear window defrost button and also controls the rear window defrost relay. PMI is required if installing a new module.

Front Display Interface Module (FDIM)

The FDIM contains a redundant rear window defrost button on the touchscreen display. The FDIM plugs directly into the APIM, and does not communicate directly on any network.

Driver Door Module (DDM)

For vehicles equipped with memory driver seat, the DDM receives power window commands from the master window control switch through a LIN. The DDM supplies the applicable voltage signals to the driver door window regulator motor to operate the window in the desired direction.

The DDM also communicates master window control switch requests to the PDM through the Medium Speed Controller Area Network (MS-CAN) to operate the passenger door window from the master window control switch. PMI is required if installing a new module.

Passenger Door Module (PDM)

The PDM receives power window commands from the passenger door window control switch or from the DDM through the Medium Speed Controller Area Network (MS-CAN). The PDM supplies the applicable voltage signals to the passenger door window regulator motor to operate the window in the desired direction. PMI is required if installing a new module.

Body Control Module B (BCM-B)

During a global open command or whenever the convertible top switch is operated (to raise or lower the convertible top if equipped), the Body Control Module B (BCM-B) sends a signal on a shared circuit to the window motors to activate a full down operation of all windows. PMI is required if installing a new module.
