I'm curious about what messages the various modules send and on which bus. I noted a hackaday blog post discussing use of a LIN bus adapter to affect console button controlled settings.

I'm curious how many data busses exist in the 2015+ 958's and what bridges exist between them.

I'm assuming they're not going to be visible at the OBD connector, is that correct?

The starting point for this would typically be a logical network diagram showing how the modules communicate. The next point would be an actual wiring schematic. I'd like to find where to start poking around to listen to the bus traffic. It'd be convenient to do things like turn on the automatic headlight feature (which seems to turn itself off all the time), the start/stop and the sport exhaust. Other conveniences would the being able to conditionally be able to turn on the seat warmers or ventilation. As in, know the time/temp and use that as a range for activating the seating features. A rear hatch close button wouldn't be unwelcome either...

 

PM me your email address. I have the "Computer Data Lines" circuit - 2 PDF pages. BTW - just looked at it - and it appears to all be CAN bus. Did a bit more poking at the diagrams.. depending on the radio "level" there also may be an optical (MOST) network, and there is something else simply called "Data" that appears to be used to do direct connections between certain modules. These additional circuits are found in other sections of the wiring diagrams. I'm guessing that the diagrams are roughly 100 pages or so (although a lot is repeated since the factory manual gives duplicates of identical systems when different engines are used.)
