Front

OPERATION

The two front heated seat switches are momentary, push button-type switches, that provide a request signal to the Cabin Compartment Node (CCN) over the Controller Area Network (CAN) data bus. The CCN then sends a message over the Local Interconnect Network (LIN) data bus 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 front seat switch LEDs are controlled by the CCN.

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