Implementation of diagnosis functions and messages
as an extension for the J1939 protocol stack

Overview of functions

The Diagnostic Extension enables the expansion of the IXXAT J1939 protocol software (version 2.02 or higher) by the diagnosis services (DM1 to DM32) as specified in J1939/73.

Diagnostic messages provide the utility needed when the vehicle is being repaired. They are also used during vehicle operation by the networked ECUs to allow them to report diagnostic information and self-compensate as appropriate, based on information received.

Diagnostic messages include services such as periodically broadcasting active diagnostic trouble codes, identifying operator diagnostic lamp status, reading or clearing diagnostic trouble codes, reading or writing control module memory, providing a security function, stopping/starting message broadcasts, reporting diagnostic readiness, etc.

To use the Diagnostic Extension the IXXAT SAE J1939 protocol software (1.02.0351.0000x) version 2.02 or higher is required.
