Hello!, I'm new to the forum, I've been working on the fiat Toro and Jeep renegade proxy alignment for 1 year, I would like to know if anyone knows the meaning of the first 12 bytes of the proxy ?
Renegade proxi bytes , I noted that when altering some function the last bytes also changes.
32 38 36 31 31 30 34 36 33 39 30 4F ..

I apriciate if someone checked this.

as far as I understand 1-5 bytes some kind of model identifier; 6-11 - looks like checksum for proxi config, but not for all models. 12th does not belong in this group.

Thank you so much shpuncik , for your reply! taking the opportunity , you konw if it´s like the checsum of a CAN protocol or serial com. ?
Best regards
Tks
