Module-Seat Memory
Description
DESCRIPTION
NOTE: The scan tool standardization process must be performed on the Memory Seat Module (MSM) any time a new module is installed or the
existing module is reflashed.
The Memory Seat Module (MSM) is located underneath the driver seat, towards the front and on the outboard side. It is used in conjunction with the
other modules in the memory system to recall the seat to one of two preset seat functional adjustments (horizontal, vertical, and recliner). The switch for
the memory seat programming and selection mounts on the driver door trim panel. The MSM also controls the adjustable pedals, both for the memory
and manual functionality. The adjustable accelerator and brake pedals are available on SLT and Limited models. On Limited, their positioning can be
stored for recall by the memory system, allowing for two drivers to have unique, pre-programmed settings.
Operation
OPERATION
POWER/MEMORY SEAT
The memory seat module receives input from the 8-way power seat switch, the driver seat position sensors, adjustable pedal control circuits (switch,
sensor, and motor), and the data bus circuit. The memory switch, is wired to the memory mirror module which sends the message over the data bus.
The memory seat module performs the following functions:
-
Positions the driver seat (vertical, horizontal, and recliner positions) and adjustable pedals.
-
Sends the memory save or recall (#1 or #2) command over the data bus circuit to the memory mirror modules, HVAC, and radio.
-
Provides for "linking" the key FOBs to memory.
-
Provides for the easy entry/exit feature.
-
Provides the tilt mirrors in reverse feature
When a memory button is pressed (#1 or #2) on the memory switch, the driver door memory mirror module sends a recall message to the memory seat
module (MSM). Then the MSM will position the driver seat and adjustable pedals to its preprogrammed location/setting. When the Remote Keyless
Entry (RKE) Transmitter button is pressed, depending on which transmitter (#1 or #2), the SKREEM (RKE Receiver) sends the recall request and FOB
number (#1 or #2) data message. This RKE transmitter function depends on if the MSM is programmed to trigger the recall (linked FOBs).
A memory setting is saved by pressing the "set" button, then pressing either the memory 1 inch or 2 inch button within 5 seconds of pressing the "set"
button.
A memory setting is recalled by pressing either the memory 1 inch or 2 inch button, or by pressing the unlock button on a "linked" Remote Keyless
Entry (RKE) transmitter.
For driver safety, memorized settings can not be recalled if the transmission is in any position other than park or the seat belt is latched.
A key FOB is "linked" to a memory setting by pressing the "set" button and then pressing either the memory 1 inch or 2 inch button within 5 seconds of
pressing the set button, then by pressing the "lock" button on the selected key FOB.
