System Operation - Exterior, Memory 

When a memory recall or save is initiated, the DSM sends the memory command message to the DDM and PDM through the MS-CAN. Based on this message, the DDM and PDM recall the requested memory preset mirror position from internal memory or save the current mirror position to correspond with the requested preset. During a memory recall, the DDM and PDM supply voltage and ground to the appropriate exterior mirror motors to achieve the desired memory positions that are stored in memory based on feedback from the mirror motor potentiometers. If the exterior mirror control switch is activated in any direction during a memory recall, the DDM sends the manual mirror override message to the DSM. After this message is received, the DSM sends the memory command message to abort the memory recall. After the recall is aborted, the DDM or PDM respond to the exterior mirror control switch inputs. A memory recall is also aborted if the driver seat control switch is activated in any direction during a memory recall.

The LH exterior mirror glass position memory presets are stored in the DDM and the RH exterior mirror glass position memory presets are stored in the PDM.

A memory recall or memory save can be initiated by the memory set switch, RKE transmitter or Intelligent Access (IA) key (if equipped) or the keyless entry keypad. For additional information on memory recall or memory save, refer to the Owner's Literature.

For additional information on the memory feature, Refer to: SEATING SYSTEM - FRONT (1 OF 2) .

System Operation - Exterior, Heated 

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.
