Memory Seat/Mirror Module: Operation
WARNING: This page is about a different car, the 2004 Dodge Grand Caravan, 2004 Dodge Caravan, and 2004 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
When memory system operation is requested (depressing of the memory switch), a resistor multiplexed signal is sent from the memory switch to the body control module (BCM). The body control module will then send the appropriate signals out to the memory/mirror seat module, the memory/mirror seat module then applies the voltage supply to the power seat track or side-view mirror if the proper requirements are met. The vehicle speed must equal zero and the transmission must be in park or neutral in order for the memory system to function.
