Circuit/System Description

The rear heated seats are a high and low mode seat cushion heater system. The heater elements are controlled by the rear heated seat module mounted to the under side of the left rear seat cushion pan. The rear heated seat switches are inputs to the rear seat audio panel and when a heated seat switch is pressed the active switch signal is sent to the rear heated seat module through the low speed LAN circuit. The rear heated seat module determines the heated seat mode based on the switch messages and sends a message to the rear seat audio panel to display the rear heated seat indicators as necessary.
