Product Information

Product Description

Diagnostic messages in J1939 are defined in the SAE specification J1939-73 and can be sent and received with the emotas J1939 Stack. Without the Diagnostic Messages extension, the Diagnostic Messages (DM) need to be interpreted by the application.

This extension provides API functions to send and receive Diagnostic Messages (DM1 .. DM64) in a more easy way.

One example is functions that combine Diagnostic Trouble Codes (DTC) from SPN, Failure Mode Indicator, Conversion Mode and Occurrence Count, and then map multiple of them into a DM that is transmitted by BAM or CMDT. Another example is special functions for the memory access and binary data transfer using DM14, DM15 and DM16.

SAE J1939 Protocol Stack with DeviceDesigner required for this extension.
