Traverse FWD V6-3.6L (2009)
Circuit/System Description
The driver and front passenger heated seats are controlled by separate heated seat switches. When a heated seat switch is pressed, ground is momentarily
applied through the switch contacts and the switch signal circuit to the heated seat module (HSM). In response to this signal, the module then applies
battery voltage through the element supply voltage circuits to the seat cushion and seat back heating elements. The HSM then supplies a ground through
the appropriate indicator control circuits to the heated seat switch illuminating the switch indicators.
