System Operation - Exterior, Heated

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

Based on the Mirror Heat Request message received from the FCIM through the MS-CAN, the DDM controls the operation of the LH heated exterior mirror glass and the PDM controls the operation of the RH heated exterior mirror glass. On vehicles equipped with a LH exterior auto-dimming mirror, the LH exterior mirror glass takes longer to defrost than the RH exterior mirror glass due to differences in the mirror glass thickness.
