Title: Canbus radio PIDs Post by: MadCow on July 09, 2014, 04:52:41 PM I'm looking into building a canbus simulator (Something like this (http://www.kufatec.com/shop/en/audi/a4/a4-b5-8d/can-bus-interface-simulator-concert-2-chorus-2-symphony)) with an arduino and a canbus shield. The hardware and software portion should be relatively simple, but since I don't have access to a B6 or late C5 I can't think of a way to find the PIDs and messages that I need to transmit to the radio. Is there any way to find these PIDs other than logging canbus communications? From what I understand these messages are broadcast by the instrument cluster, but would I be able to find any useful information from the radio by itself?

0x261 8bytes frame: top RDS line 0x263 8bytes frame: bottom RDS line you need yet to tx radio keepalive message also |
