Circuit/System Description

Reference voltage is supplied to the memory seat adjuster switch from the driver door lock/window switch. When a memory switch is pressed, reference voltage is applied through the switch contacts, a series of resistors and thorough the memory switch signal circuit to the door lock/window switch. The door lock/window switch then sends a serial data message to the memory seat module (MSM) indicating the memory recall request. The MSM then commands the appropriate seat motors to move to the pre-recorded seat positions stored in memory in response to the switch input.
