Memory/Heated Seat Adjustable Pedal Module - Description
DESCRIPTION
A Memory Heated Seat/Adjustable Pedal Module (MHSAPM) is used on vehicles that are equipped with the heated seat system option. A Memory
Seat/Adjustable Pedal Module (MSAPM) is used on vehicles that are not equipped with the heated seat system option. This module contains all the
software and control logic for the front memory/heated and power seat systems, as well as the adjustable foot pedal system. The MHSAPM contains a
central processing unit and interfaces with the Programmable Communications Interface (PCI) data bus circuit.See: Body and Frame/Seats/Seat
Heater/Description and Operation/Heated Seats - Description, for more information on the heated seat system. See: Body and Frame/Seats/Description
and Operation/Power Seat System - Description, for more information on the power/memory seat system.
The MHSAPM is packaged in a black molded plastic case which is mounted under the edge of the driver side front seat cushion (4). This location makes
it somewhat difficult to access because it sits between the power seat track and the seat cushion frame. See: Service and Repair/Memory/Heated Seat
Adjustable Pedal Module - Removal, for detailed removal and installation instructions.
For diagnosis of the MHSAPM or the PCI data bus, a diagnostic scan tool and the appropriate Diagnostic Information are recommended. The MHSAPM
cannot be adjusted or repaired and, if inoperative or damaged, it must be replaced.
