Greetings, I was wondering as I have been searching a while now, is there any complete list of bytes explaining which module controls or what it does?

There is no official list anywhere on the WEB/Internet. Much sought after for many years. Any such lists / details are, to my knowledge, not even available to main dealers. Basically FCA and unit manufacturer only OR some advanced diagnostic/configuration kit manufacturers under non disclosure/confidentiality agreements. These people have probably also paid a lot of money for the information and and disclosure by then will damage their equipment sales.

Any Proxy byte information out there in the wild has generally come from other people. Also any such data is often specific particular makes/models.

All you or anybody else can do is search this forum, all Italian, FCA car forums looking for Proxy data and compile your own list.

Understood, thanks a lot for your quick reply mate!
