Memory Seat/Mirror System Operation

WARNING: This page is about a different car, the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, and 2003 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

The Memory Heated Seat/Mirror Module receives hard wired inputs from the memory seat switch and the potentiometers, Mounted on each of the driver power seat track motors and both side view mirrors. The programmed software in the MHSMM allows it to know where the seat/mirror is located in its designed travel by a resistance reading generated from the seat track or mirror mounted potentiometer. This way, when the memory switch is depressed the module will power the seat track or mirror motors unit the correct preset location is achieved. The MHSMM will prevent the seat memory recall function from being initiated if the transmission gear selector lever is not in the Park or Neutral positions, or if the vehicle is moving. These inputs are monitored over the PCI data bus circuit.
