Under normal operation, the Steering Wheel Control Switch receives a ground from the PCM. The Heating, Ventilation, and Air-Conditioning (HVAC) Module – Electronic Automatic Temperature Control (EATC) senses the resistance (depending on what button is pressed) from the Steering Wheel Control Switch. The Diagnostic Trouble Code (DTC) sets when the module senses no voltage drop on the reference voltage circuit, indicating an open circuit.
