Memory Functions

Left front power window switch receives the signals from the memory function switch. The left front power window switch then sends a message through Simple Bus Interface (SBI) to Driver Door Module (DDM). The message indicates that the switch received a memory function signal. DDM then sends a message to the MSM through the class 2 serial data line. The MSM records the current lumbar support positions for 2 different drivers.

In order to record the current seat positions, press and hold MEMORY 1 or MEMORY 2 buttons for 3 seconds. A chime will sound in order to acknowledge the signal. When MSM receives a memory set message, MSM records feedback voltages from sensors for the appropriate driver. When you press one of the memory buttons, a single chime sounds in order to acknowledge the signal. From the memory buttons, the MSM receives the memory recall message. The MSM then applies battery positive voltage to seat motors until position sensor feedback voltages equal feedback voltages stored in memory for appropriate driver.
