Diagnostics

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:

1. 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.
2. 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.

   
   
3. Results: Based on the filters, a list of assets will be displayed with the following information:

   Asset	Displays which asset reported the MIL, Check Engine, or Stop Engine lamp on from its ECM.
   Date/Time	Will display the time the ECM recorded the lamp going on.
   Mil	Will be blue if the Malfunction Indicator Lamp is/was active.
   Check Engine	Will be yellow if the Check Engine Lamp is/was active.
   Stop Engine	Will be red if the Stop Engine Lamp is/was active.
   Type	Select if you want to view assets reporting on the 1708 Protocol, 1938 Protocol, or OBD-II protocol.
   SA	Displays the Source Address for the vehicle’s electronic system reporting the JBus event in the J1939 protocol.
   MID	Displays the Message ID which is a unique source address for the vehicle’s electronic system reporting the JBus event in the J1708 protocol.
   SPN	Displays the Suspect Parameter Number, which is a number assigned by the SAE (The Society of Automotive Engineer) to describe the specific parameter.
   FMI	Displays the Failure Mode Indicator, a code from 0-32 reported by the vehicle for that specific fault.
   PID/SID	Displays the Parameter Identifiers (PID) or Subsystem Identifiers (SID), which identify subsystems of the electronic systems reporting the fault.
   Is PID	Displays whether the PID/SID column is PID or SID. “True” means it is PID, “False” means it is SID.
