Diagnostics displays your vehicle’s ECM fault code information.
A benefit of this report is it can be used as an early warning and remote monitoring system.
To access the Diagnostics report:
- From the main menu, click Reports, then go to Fuel, Diagnostics & Usage and click Diagnostics.
Note: This is only a log of faults received and may not reflect the current status of the system which reported a fault.
- Filters: Narrow down the number of assets returned in the diagnostics report.
Asset # Select an asset from the drop-down menu, or leave the default to “select asset” to display all assets with fault codes. Protocol Select a protocol (1708, 1939, or OBD-II). Date Range Select the range of date and time to appear in the report. VIN Enter a specific asset VIN to display in the report results. Mil Select the Mil check-box to include assets that have the Malfunction Indicator Lamp (MIL) on. Check Engine Select the Check Engine check-box to include assets that have the Check Engine lamp on. Stop Engine Select the Stop Engine check-box to include assets that have the stop Engine lamp on. Valid VIN’s Only Select Valid VINs Only, means the report will only display assets with VINs that were correctly identified on the ECM. Fault Status Filter the report based on the status of the fault code received by the device. This is only a log of faults received and may not reflect the current status of the system which reported a fault. Inactive fault codes are currently only supported with Cummins Connected Diagnostics.
