Memory Seat System Description

The Memory Seat Module controls the movement of the 4 seat position motors. The motors that the Memory Seat Module can operate when memory is recalled is the horizontal motor, the front vertical motor, the rear vertical motor, and the recline motor. Battery positive voltage for memory motor movement is supplied through a circuit breaker to the Power Seat Switch and the Memory Seat Module. The ground path is provided through the Memory Seat Module ground circuit. For information on how the motors operate with the Power Seat Switch and the Memory Seat Module, refer to Power Seats System Description and Operation .

Memory Inhibit/Enable

The Power Seat is able to adjust to predetermined positions when requested to by the Memory Seat Switch. The Power Seat will move to the last position that set into memory. The Memory Seat Module receives all input from the Memory Seat Switch through the Memory Seat Switch signal circuits. When the ignition switch is in the OFF position, setting memory position, memory recall 1 and 2 , and personalization recall are all allowed. When the ignition switch is turned to the ON position and the gear selector is in the PARK position, only the recall personalization function is deactivated and all other memory functions are allowed. When the ignition switch is in the ON position and the gear selector is out of the PARK position, memory record is allowed, but all other memory seat functions are not allowed. This prevents the Memory Seat Module from changing the position of the seat when the vehicle is moving. For information on how to set and personalize the memory seat refer to Driver Personalization .
