Driving Position Memory System (DPMS)

System Description
The driver's seat has a memory feature. All the adjustments can be memorized by pressing the MEMO button on the driving position memory switch, and then pressing one of two position buttons within 5 seconds. Pressing the appropriate position button will move the seat to the memorized positions.

This system is integrated with the multiplex integrated control system, and has 9 wake-up and sleep modes. All digital signals are sent via shared B-CAN and UART communication lines. For more information about communication line and wake-up/sleep mode, Refer to the Multiplex Control System Description.

Disconnecting the battery will cancel the memorized positions.

Memorizing a Seat Position
Move the seat to the desired position. Turn the ignition switch ON (II).

Press and hold the MEMO button on the driver's position memory switch. A single beep will be heard and both of the green LEDs will begin to flash. Press No. 1 or No. 2 to match the remote that is to be used. There will be two more beeps confirming that the seat positions have been memorized. The LED will remain lit, unless the seat is moved from the memorized position.




Memorized Position Recall with the Remotes
Make sure that the remotes are LINKED. Press and hold the LOCK and UNLOCK button at the same time. The red LED on the remote will flash ONE time when the remote has been LINKED, and will flash TWO times when the remote has been UNLINKED. After the seat position has been memorized, the seat will move to the position when the remote UNLOCK is pressed and the driver's door is opened. When the seat gets to the memorized position, the LED corresponding with that remote will stay lit until the position is changed or the key is turned OFF.

Power Seat Position Sensors
Each motor has a sensor that detects motor rotation and sends a pulse to the power seat control unit when the motor rotates. The control unit stores the number of pulses in its memory, and the seat position is memorized.
