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.
Conditions for Setting the DTC
B2425 04 or B2430 04
The module does not detect a temperature change within 210 seconds.
