Commander 4WD V8-4.7L Flex Fuel (2009)
The two momentary, push button-type heated seat switches provide a hardwired resistance signal to the Electro Mechanical Instrument Cluster (EMIC)
(also known as the Cab Compartment Node/CCN). The instrument cluster then sends a message via the Controller Area Network (CAN) data bus
network to the heated seat module, signaling the module to energize the heating element for the selected seat. Light Emitting Diodes (LED) in each
switch indicate the level of heat in use. The switch LEDs are controlled by the instrument cluster.
The two LED indicator lamps and the incandescent bulb in each heated seat switch cannot be repaired. If the indicator lamps or back lighting bulb are
inoperative or damaged, the individual heated seat switch must be replaced.
