Displayed Input Status

The scan tool can also display the status of the various HVAC inputs. Select the HVAC input status display in order to read the data and determine if the inputs can be properly interpreted. The display also indicates if the input has changed states. For example, when the outside temperature changes, the scan tool will display the change of the input status of the outside air temperature sensor. Use this kind of information when diagnosing a malfunction associated with a particular HVAC input or an input that is shared with another system.
