Description - Memory System

WARNING: This page is about a different car, the 2004 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.

The memory system is capable of storing two different position settings for the outside rearview mirrors, driver seat and foot pedals and up to twenty (ten AM and ten FM) radio station presets. The driver door module (DDM) is the memory system master, it lets the other modules in the vehicle know if the vehicle is equipped with the memory system. It also makes the requests to the other modules to set or recall their specific settings. The driver door module stores and recalls the driver outside mirror position. The PDM stores and recalls the passenger outside mirror position. The radio stores and recalls the preset stations and the memory heated seat adjustable pedal module (MHSAPM) stores and recalls the adjustable pedals and driver seat positions.

The memory system will automatically recall all of the previously set "positions" when the corresponding numbered one (1) and two (2) buttons of the memory switch are depressed, or when the doors are unlocked using the Remote Keyless Entry (RKE) transmitter. If the remote link to memory feature is enabled through the EVIC, and the key fob has been linked (pressing SET then one (1) or two (2) on the door followed by depressing the lock switch on the key fob) depressing the unlock switch on the RKE fob will move the seats, pedals, mirrors and radio stations to the linked position. The Body Control Module enables the customer programmable features that are displayed on the EVIC display, in the cluster.

The memory system also has a customer programmable easy exit feature that will move the driver seat rearward 55 millimeters (two inches) or to the end of its travel, whichever occurs first, when the key is removed from the ignition switch lock cylinder.

Certain functions of the memory system rely upon resources shared with other electronic modules in the vehicle over the Programmable Communications Interface (PCI) data bus network. The PCI data bus network allows the sharing of sensor information.

This system provides increased reliability, enhanced diagnostics, and allows the addition of new feature capabilities. For diagnosis of the electronic modules or of the PCI data bus network, the use of a DRB III(R) scan tool and ELECTRONIC CONTROL MODULES are recommended.

Electronic modules that may affect memory system operation are as follows:

Memory Seat Adjustable Pedal Module (MSAPM) or Memory Heated Seat Adjustable Pedal Module (MHSAPM) - Refer to Memory (Heated) Seat Adjustable Pedal Module in ELECTRONIC CONTROL MODULES for more information.
