FRONT

The two front heated seat switches are momentary, push button-type switches, that provide a request signal to the Heated Seat Module (HSM) (also know as the comfort seat wheel module), over the Controller Area Network (CAN) bus, signaling the HSM to energize the heating element for the selected seat. Light Emitting Diodes (LED) in each switch indicate the level of heat in use. The front seat switch LEDs are controlled by the HSM.

The front heated seat switches are diagnosed using a scan tool Testing and Inspection.

The front heated seat switches cannot be adjusted or repaired and if a switch or its LEDs are damaged or inoperative, the entire A/C-heater control must be replaced.
