Circuit/System Description
When the heated seat function is active, the memory seat module (MSM) supplies battery voltage through the element supply voltage circuit to the
seat heater elements. The module controls the seat temperature by providing a PWM ground through the heated seat element control circuit to the
seat heater elements. The module then monitors the current flow through the heating element and the temperature sensor rate of change to verify
correct operation.
Conditions for Running the DTC
The MSM must be powered and the heated seat must be enabled.
Conditions for Setting the DTC

The module does not detect a temperature change within 210 seconds.
