Data Display
Use a scan tool to display DCM data. This information assists in determining whether the DCM is operating properly and whether the DCM is sending or receiving the proper data to and from a particular system. The DCM uses data received from other systems in order to carry out some functions. Therefore, if the DCM receives the incorrect data from another system, the DCM may function improperly. Use the scan tool in order to review the data from systems that interact with the DCM.
Displayed Input Status
The scan tool also displays the DCM input status. Select the DCM input 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 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 DCM input or an input that is shared with another system.
Cycle Outputs
Use a scan tool in order to cycle the DCM output functions. When the DCM output cycling is selected, the scan tool can command the DCM to cycle an output. This feature can be used to determine if the DCM is able to cycle an output regardless of the inputs or any specific program instructions. Once a test is selected, the scan tool will command the DCM to energize the selected output. The scan tool then displays the status of the selected output. The displayed information represents only what was DCM commanded, not what action was actually taken. Check if the DCM is actually preforming each of the selected output functions.
