Heated Mirrors

The mirrors heat during the defrost/defog cycles for the rear window. The heated mirrors are connected to the Driver Door Module (DDM) and the Passenger Front Door Module (PDM). The DDM receives a class 2 message from the Instrument Panel Cluster (IPC) via the Rear Integration Module (RIM) commanding the heated mirrors ON. The DDM also examines information from the Dash Integration Module (DIM) to determine if vehicle conditions are correct for the heated mirrors function to occur. If conditions are correct, the DDM then commands the driver side mirror heater ON, and sends a power door serial data message to the passenger front door module (PDM) to command the passenger side mirror heater ON.

The DDM supplies battery positive voltage to the LH outside rearview mirror heating element via the feed circuit, and ground via the return circuit. The PDM supplies battery positive voltage to the RH outside rearview mirror heating element via the feed circuit, and ground via the return circuit.
