Circuit/System Description

The driver and front passenger heated seats are controlled by the memory seat module (MSM). When active, power is applied to the seat cushion

and seat back heater elements through a common voltage supply circuit. The module controls the seat temperature by providing a pulse width

modulated (PWM) ground through the heated seat element control circuits to the seat heater elements. The module then monitors the current flow

through the heating elements and the of rate change of the temperature sensors to verify correct heated seat operation.

Conditions for Running the DTC

The MSM must be powered.
