Commander 4WD V8-4.7L VIN N (2006)
-
Provides for "linking" the key FOBs to memory.
-
Provides for the easy entry/exit feature.
When a memory button is pressed (number 1 or number 2) on the memory switch, the Driver Door Module (DDM) sends a recall message to the MSM.
The MSM will then position the memory system components to the preprogrammed location/setting. When the Remote Keyless Entry (RKE) Transmitter
button is pressed, depending on which transmitter (number 1 or number 2), the SKREEM (RKE Receiver) sends the recall request and FOB number
(number 1 or number 2) data message. This RKE transmitter function depends on if the MSM is programmed to trigger the recall (linked FOBs).
A key FOB is "linked" to a memory setting by pressing the "set" button and then pressing either the memory "1" or "2" button within 5 seconds of
pressing the set button, then by pressing the "lock" button on the selected key FOB. The memory system "Easy Entry and /Exit" feature provides the
driver with more room to enter or exit the vehicle. When the seat is in a memorized position, it will move rearward 55 millimeters or to the end of its
travel, whichever occurs first, when the key is removed from the ignition switch lock cylinder. This is a customer programmable feature of the overhead
console. The seat will return to the memory position when the driver turns the vehicle's ignition switch out of the LOCK position.
The memory system "learns" the seat and adjustable pedal motor maximum end positions when the motor reaches the limit of travel in any direction and
stalls. Subsequently, movement will stop just short of that position to avoid extra stress on the motors and mechanisms. If the system learned a maximum
position as a result of an obstruction, as for instance if a large object was placed on the floor behind the seat, the system can relearn the "true" maximum
position through manually operating the power seat after the obstruction is removed.
NOTE: It is normal for the power accessories contained in the memory system to stop at the maximum "learned" position and then continue to the
"true" maximum position when the control switch is released and then applied in the same direction a second time.
Certain functions and features of the memory system rely upon resources shared with other electronic modules in the vehicle over the Controller Area
Network (CAN) bus. The CAN bus allows the sharing of sensor information. This helps to reduce wire harness complexity, internal controller hardware,
and component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many
new feature capabilities. For diagnosis of these electronic modules or of the CAN bus, the use of a scan tool and the proper diagnostic information are
needed.
