Driver Power Seat With Memory

WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Verify good battery condition before diagnosing the memory seat system. Poor battery condition can interfere with memory seat operation, even if vehicle starting is possible.

NOTE: A memory recall in progress does not prohibit the initiation of another memory recall; the most recently requested memory recall is executed.

The Driver Seat Module (DSM) controls the driver power memory seat. The DSM is located underneath the driver seat. The memory seat feature allows the driver to program a personalized seat position that can be recalled using the memory SET switch or a Remote Keyless Entry (RKE) transmitter. There are 2 memory settings possible.

For information on programming memory positions or recalling a stored memory position, refer to MEMORY POSITION PROGRAMMING . For information on RKE transmitter programming or to diagnose a concern, REFER to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS .

The NEUTRAL position of the driver seat control switch is at a ground state through the seat control switch normally-closed contacts. The driver seat control switch provides voltage to the DSM only when activated. A voltage input causes the DSM to power the appropriate motor until the input is removed. Ground is the normal state of the motor circuits through the DSM. The DSM internally switches the appropriate circuit from ground to voltage to operate the motors.

As the seat is adjusted, the DSM monitors the motor position sensors to record the current seat position. The DSM removes voltage from the motor upon termination of the seat control switch input or if the DSM does not detect movement from the motor while monitoring the position sensor during a memory recall operation.

The DSM communicates DTCs and other information using the MS-CAN. REFER to MODULE COMMUNICATIONS NETWORK for information concerning MS-CAN.

This section only diagnoses concerns specific to the memory seat. To diagnose an exterior mirror concern, REFER to REAR VIEW MIRRORS . To diagnose a power adjustable pedal concern, REFER to HYDRAULIC BRAKE ACTUATION . To diagnose a power steering column concern, REFER to STEERING COLUMN .
