Memory System

MEMORY SYSTEM

The Memory Seat Mirror Module (MSMM) receives battery current through fuse #22 in the Integrated Power Module (IPM) and the power seat system circuit breaker, located under the driver side front seat near the rear edge of the seat cushion pan. The memory system does not operate with the Ignition-Off Draw (IOD) fuse removed. The MSMM will drive a maximum of 2 motors at a time in a given direction. If conflicting directions are requested, the priority for response will be approximately as follows:

- Seat Track Rearward or Forward
- Seat Front Down or Up
- Seat Rear Down or Up
- Recliner Rearward or Forward

The inputs from these switches to the MSMM is a current limited battery source fed by the MSMM. This protects the MSMM printed circuit board traces from acting as fuses. All of these switch contact inputs to the MSMM are normally closed to ground, except when actuated.


For diagnosis of the MSMM, the Programmable Communication Interface (PCI) data bus, or the other electronic modules on the PCI data bus that provide inputs and outputs for the memory system, the use of a DRBIII(R) or equivalent scan tool and the proper Diagnostic Procedures information is recommended.


ELECTRONIC VEHICLE INFORMATION CENTER


The Electronic Vehicle Information Center (EVIC) serves as the user interface for the memory system. It displays memory system status messages and provides the user with the means for enabling and disabling the many customer programmable features available on the vehicle, including those for the memory system.
