As an ex-blinky-lights-and-radio tech, I can assure you that they are clearly separated.
Admittedly, my experience is limited to BMWs, but there's enough shared knowledge across the industry about the Right Way to do this stuff that I'd be surprised if Jaguar had made that mistake.
- topbanana 15y agoI have heard that there are separate buses for these things, but how does information propagate between them? For example, if my ABS fails, how does it pop up into the service menu on iDrive?
- regularfry 15y agoThe instrument pack in the dashboard is connected to both buses. It needs real-time data from the drive systems to display speed and so on, so it's used as a hub.
