Seat Heater Switch: Description and Operation
Heated Seat Switch - Operation
OPERATION
The heated seat switches are active any time the Local Interface Network (LIN) data bus is active. Depressing the heated seat switch provides a switch
status message to the Cabin Compartment Node (CCN) via the LIN data bus. The CCN is responsible for supplying the LIN data bus message to the
heated seat module, signaling the module to power the heated seat element of the selected seat and maintain the temperature setting. If the heated seat
switch is depressed to a different position (Low or High) than the currently selected state, the CCN will go through the process again to change the
temperature setting.
