Add Exception

 

Add an Exception when there is a need to ignore a unique and non-essential SPN/SOURCE/FMI codes from a vehicle.  The numbers in the SPN/FMI/SOURCE columns denote J1939-defined values to show what J1939 input to ignore. For example, a SPN (Suspect Parameter Number) of 110 is fault code for a Caterpillar-specific J1939 Descriptor value (Engine Coolant Temperature).

 

SPN: Suspect Parameter Number that identifies the parameter sending the fault code error message. A SPN code is identified by some vehicle manufacturers as a Parameter Identifier (PID).

 

FMI: Failure Mode Identifier that is used to identify the type of fault detected. A fault or trouble code will be accompanied with a corresponding FMI value.

 

SOURCE: Source Address identifying the Electronic Control Unit that is sending the Diagnostic Trouble Code.

 

 

From the Edit Configuration view, click Add Exception to add a row to the Exception Dialog Box. Click Add Exception again to add more rows. The selections are saved automatically. Click Done after completing the entries.
