Heated Mirrors

The mirrors heat during the defrost/defog cycles for the rear window. The heated mirrors are connected to the system that heats the rear window for the defrost/defog function When the Instrument Panel Module (IPM) receives the message that the rear defrost/defog has been activated, it sends a Serial Data Class 2 message to the DDM and the PFDM to Heat the mirrors. Power and ground are then supplied to the mirrors by the DDM and the PFDM.
