Circuit Description

How the Circuit Works
The driver's seat has a memory feature. The four driver's seat adjustments (forward and back, front up and down, rear up and down, and seat back angle) can be regulated separately. All of the adjustments can be memorized at the same time by pressing the MEMO button of the driving position memory switch, and then (within five seconds) pressing one of the two position buttons. If the same position button is pressed after the adjustments are memorized, the seat will move to the memorized positions.

NOTE: Disconnecting the battery will cancel the memorized positions.

Remote Transmitter Operation
The driving position memory system is directly connected to the remote transmitters 1 and 2. When the doors are unlocked using either the remote transmitter 1 or remote transmitter 2, the corresponding memory position 1 or 2 is activated.

Power Seat Position Sensors
Each driver's power seat motor has a corresponding sensor, which sends a pulse to the power seat control unit when the motor rotates. The power seat control unit then stores the number of pulses for that seat position in its memory.
