Scan Tool Displayed Input/Output Status

The Scan Tool also displays the module input/output status. Select the module input/output status display in order to display the data and determine if the switched inputs/outputs can be properly interpreted. The display also indicates if the input/output has changed states. For example, when a door is closed, the Scan Tool displays the input status of the door ajar switch as INACTIVE. When the door is open, the scan tool reads ACTIVE. Use this kind of information when diagnosing a malfunction associated with a particular module input or an input that is shared with another system.
