Displayed Input Status

The scan tool also displays the instrument cluster input status. Select the instrument cluster status display in order to display the data and determine if the switched inputs can be properly interpreted. The display also indicates if the input has changed states. For example, when the engine coolant level is OK, the scan tool displays the input status of the engine coolant level switch as INACTIVE. When the engine coolant level is low, the scan tool reads ACTIVE. Use this kind of information when diagnosing a malfunction associated with a particular instrument cluster input or an input that is shared with another system.
