Circuit/System Description

The left and right rear passenger heated seats are controlled by separate heated seat switches. The switches are located on the rear door panels. When a heated seat switch is pressed, ground is momentarily applied through the switch contacts and the switch signal circuit to the rear heated seat module. 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 heated seat module then supplies a ground through the appropriate indicator control circuits to the heated seat switch illuminating the appropriate indicators.
