Operation CHARM: Car repair manuals for everyone.

Description







DESCRIPTION





Vehicles equipped with the memory system have a memory switch (1) mounted to the driver side front door trim panel (9). This switch is used to set and recall all of the memory system settings for up to two drivers. The memory switch is a resistor multiplexed unit that is hard wired to the left Front Door Module (FDM). The left FDM in turn sends out the memory system set and recall requests to the other electronic modules over the Controller Area Network (CAN) data bus.

The memory switch cannot be adjusted or repaired and, if inoperative or damaged, it must be replaced.
