Memory Function Switch

The LH front power window switch receives inputs from the memory function switch. The LH Front Door Module (LFDM) supplies a reference ground to the memory function switch via CKT 351 (BLK/WHT). When the SET button is pressed, the set input of the LH front power window switch is temporarily grounded through the memory function switch via CKT 614 (ORN). When the 1 button is pressed, the 1 input of the LH front power window switch is temporarily grounded through the memory function switch via CKT 616 (PPL). When the 2 button is pressed, the 2 input of the LH front power window switch is temporarily grounded through the memory function switch via CKT 615 (WHT). When the EXIT button is pressed, both the 1 and 2 inputs of the LH front power window switch are simultaneously grounded through the memory function switch via CKT 616 (PPL) and CKT 615 (WHT). After receiving an input from the memory function switch, the LH front power window switch sends a simple bus interface message to the LH front door module (LFDM). In response, the LFDM sends a class 2 message to the memory seat module (MSM) indicating that a memory function has been requested.
