Memory Master

The Driver Door Module (DDM) is the memory master. It tells all of the other modules when to set (store) and when to recall their respective component(s) position/setting (1 or 2). The system functions as follows:

• After pressing the Memory Set Switch (#1 or #2), the DDM receives and interprets the analog signal and then sends a PCI Bus message to the Passenger Door Module (PDM), the Memory/Heated Seat Adjustable Pedal Module, and the Audio System to set or recall the:
  • Memory mirror position (1 or 2). The DDM and the PDM store the setting for the respective mirror's position.
  • Memory seat position (1 or 2). The MHSAPM/MSAPM stores the setting for the seat position.
  • Pedal position (1 or 2). The MHSAPM/MSAPM stores the setting for the pedal position.
  • Radio setting (1 or 2). The Audio System stores the setting for the radio.
