The unified diagnostic services (UDS) protocol in ISO 15765-4 seems to be specifically designed for bus systems with a message length of eight bytes (for example, CAN). Now, new transport layers like FlexRay support messages with more than eight bytes.

Is it possible to adapt UDS for those layers? If so, how? Is there a planned update for that standard?

Bruno, I rolled back your tag edit. The Flexray tag didn't exist yet, and it's unlikely that it will be used in other questions. – stevenvh Jul 23 '12 at 16:14
