Memory Function

The driver's door switch assembly (DDSA) receives the signals from the memory function switch. The (DDSA) then sends a message via the simple bus interface to the driver door module (DDM) indicating that a memory function signal has been received. The DDM then sends a message to the memory seat module (MSM) via class 2 serial data line. The current seat position may be recorded for 2 different drivers. To record a position, adjust the drivers seat, including the lumbar adjustments, and both outside mirrors to a comfortable position, then press and hold button 1 for 5 seconds, a double beep will sound each time a memory position is set. A second mirror and seating position may be programmed by repeating the above steps and pressing button 2. When the MSM receives a memory set message, the MSM records the feedback voltages from the position sensors for the appropriate driver. The easy exit position is programmed by moving the seat to the desired exit position and then holding the exit button for 5 seconds. Two exit positions can be programmed, one for each driver. 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. The lumbar is not involved in the easy exit function.

When the memory recall 1 or 2 button is pressed, a single chime is sounded through the radio in order to acknowledge the signal 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 signal 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.

Memory recall will not work if the shift lever is out of NEUTRAL (N) or PARK (P).
