Power Seat Switch: Description and Operation
Memory Set Switch
CS Driver Seat Switch Assembly
The memory set switch is one of eight separate switches ganged together in driver seat switch assembly. The switch is located on the drivers front door
trim panel. The memory set switch will flash red when pressed until a position button is pressed or it times out. The driver seat switch assembly can
provide up to six major resistive multiplexed inputs into the driver door module. The inputs can include memory, heated seat, seat front up/down and
foot pedal forward, seat rear up/down and pedal backwards, seat forward/backward and lumbar aft., recline forward/backward and lumbar backwards.
All inputs are hardwired resistive mux to the driver door module to decode axis direction or seat heat level. Refer to Driver Door or Memory Heated Seat
Adjustable Pedal Modules for additional information.
The memory set switch cannot be adjusted or repaired and, if faulty or damaged, the complete driver seat switch assembly must be replaced.
When any of the memory switches are depressed, a resistance signal is sent to the Driver Door Module via hard wired connections. The memory set
switch LED will flash red when pressed until a position button is pressed or the system times out. The driver door module then sends the request to the
Memory Heated Seat Adjustable Pedal Module (MHSAPM) via the PCI data bus circuit. The MHSAPM is responsible for controlling the 12v battery
feed and ground path to the power seat track or adjustable pedal motor(s) to control the seat or pedal assembly accordingly.
