Are you trying to build an ECU simulator?
I am trying to implement the CAN mode 3 (DTCs). I am using the software ScanMaster-ELM and Digimoto to do the tester.
When I send a request 7DF 8 01 03 00 00 00 00 00 00 where 7DF is ID, 8 = nº bytes of the CAN frame, 01 additional bytes, 03 is the mode 3
I want to response, for example, with 7E8 8 04 43 01 02 34 AA AA AA, where 7E8 is ID, 8 nº bytes, 04 additional bytes, 43 is mode 3 response, 01 number of DTCs, and 02 34 is the DTC P0234.
When I send this response to the programs, ScanMaster and Digimoto do not detect the response.
What could be happening?

Yes, I am trying to build an ECU with all modes with CAN protocol
