I wonder - did you try to ask Ford for a .dbc-file containing the desired IDs to query? It's worth a shot plus those files save a ton of time.

- kingbirdy 9y agoIs that really the kind of file Ford would just hand out? Seems like it could really up their liability if there was a CAN related vuln found via that handout
- mrpippy 9y agoFord is more open about vehicle info than any other carmaker I can think of (see http://openxcplatform.com http://openxcplatform.com), but that's not saying much, and I don't think they would give out dbc files without a lot of lawyers being involved.
- exabrial 9y agoIIRC, US Law mandates a bunch of CAN IDs for general engine diagnostics like fuel flow, o2 sensors, etc. The rest of the CAN IDs are unique to every manufacturer. GM (for instance) Tech Scan tool knows these CAN IDs. Independent 3rd parties can develop a simliar tool and license the CAN IDs from GM for a hefty fee. I imagine Ford has the same service available.
- amenod 9y agoWould it be possible to feed CAN IDs to Tech Scan tool sequentially and thus decode their meaning? Would it be legal?
- exabrial 9y agoMight be easier to dump the scan tools firmware. Both are probably about the same legality! :D
- emidln 9y agoEasier to bribe some intern or entry-level engineer who has the excel file mapping all the signals from every module on the bus. These used to be passed around pretty openly at the suppliers I worked for, and interns started out making something like $11.50/hr with no benefits.
- ingenieroariel 9y agoI have been trying to find one for the Ford Fusion but no luck. So I put together a github project where each can code is a github issue. https://github.com/autti/abraham/issues/45 https://github.com/autti/abraham/issues/45.
