F 550 2WD Super Duty V8-6.4L DSL Turbo (2008)
Power Seat Control Module: Description and Operation
DRIVER SEAT MODULE - MEMORY SEAT
NOTE: This vehicle uses 2 different driver seat modules (DSMs) and will be referred to as early production and late production. The circuit locations at
the connectors are different and the DSMs are not interchangeable. For additional information, refer to principles of operation in Seats. See: Testing and
Inspection/Initial Inspection and Diagnostic Overview/Principles of Operation
The driver power bucket seat, exterior mirrors and adjustable pedals are controlled by the driver seat module (DSM) when the vehicle is equipped with
the programmable/recall memory option. The DSM is located on the driver seat track.
This system allows automatic positioning of the driver seat, exterior mirrors and adjustable pedals to 2 programmable positions. Memory positions can
be stored at any time. A memory recall can be initiated only if the vehicle is in PARK or NEUTRAL gear and the ignition switch is not in START. A
memory recall in progress will not be affected by moving the ignition switch to START or by moving the gearshift lever out of PARK or NEUTRAL.
For information on programming memory positions or recalling a stored memory position, refer to Memory Position Programming. See: Testing and
Inspection/Programming and Relearning
