Hi.
iso 15765-4 (can 11/500) how to distinguish diagnostic from service messages???
So there is closed (IPDM) and open(BCM) CAN in the vehicles.
What I mean by open is that the massages between ECUs(nods) SERVICE MASSAGES and DIAGNOSTIC massages from Diag device(OBD2) flays out on the same bus.
So my question is
How to determine, distinguish the SERVICE message and DIAGNOSTIC massage? What is the difference between them?
Im attaching the protocol description PDF. I was unable find that info in description.
