Memory Functions

The LH front power window switch receives the inputs from the memory function switch. The LH front power window switch then sends a message via the Simple Bus Interface (SBI) to the driver door module (DDM) indicating that memory function input has been received. The DDM then sends a message to the Memory Seat Module (MSM) via class 2 serial data line. The current lumbar support positions may be recorded for two different drivers. To record the current seat positions, the MEMORY- 1 or MEMORY-2 button is pressed and held for three seconds, which is followed by a chime to acknowledge the input. When the MSM receives a memory set message, it records the feedback voltages from the three seat position sensors and the recline sensor for the appropriate driver.

When the MEMORY-1 or MEMORY-2 button is pressed, a single chime is sounded to acknowledge the input and the MSM receives the memory recall message. The MSM then applies battery positive voltage (B+) to the seat motors until the position sensor feedback voltages equal the feedback voltages stored in memory for the appropriate driver.
