Memory Functions

The left front power window switch receives the inputs from the memory function switch. The left front power window switch then sends a message via the simple bus interface to the Left Front Door Module (LFDM) indicating that memory function input has been received. The LFDM then sends a message to the Memory Seat Module (MSM) via class 2 serial data line. The current position may be recorded for 2 different drivers. To record the current position, the SET button is pressed followed by the 1 or 2 button, which is followed by a chime to acknowledge the input. When the MSM receives a memory set message, the MSM records the feedback voltages from the position sensors for the appropriate driver. To record an easy exit position, the SET button is pressed followed by the EXIT button and the 1 or 2 button, which is followed by a chime to acknowledge the input. When the MSM receives a set easy exit message, the MSM records the feedback voltages from the three seat position sensors and the recline position sensor for the appropriate driver.

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