Seat Memory Switch: Description and Operation
Memory Switch Location
Vehicles equipped with the memory system have a memory switch mounted to the driver side front door trim panel. This switch is used to set and recall
all of the memory system settings for up to two drivers. The memory switch is a resistor multiplexed unit that is hard wired to the Body Control Module
(BCM). The BCM sends out the memory system set and recall requests to the other electronic modules over the Programmable Communications
Interface (PCI) data bus.
The memory switch cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
The memory switch has three momentary switch buttons labeled Set, 1 and 2. When the memory set switch is depressed, a resistance value is sent to the
Body Control Module (BCM) via hard wired connections. When the memory system is in "set" mode a chime will be generated by the BCM.
