I am wanting some advice on where to go with learning more about the electronic systems used in modern cars. I have a basic understanding of how the systems work, (ECU, BCM, etc) but I'm wanting references for books, videos, websites on it, as I've watched most of the Youtube vids, and found a few websites that focus only on basics and code definitions. The 2 books I've found seem to only focus on code definitions and diagnosis, whereas I'm wanting more of the technical stuff, signals, sensor types, capabilities, etc. I find it very neat that most new cars are actually running a whole network with all kinds of sensors, switches, valves, etc. and it's all tied in over a 2 wire network. My car, for instance has 5 different computer modules that tie in together over the CAN bus. The hybrids like Prius and Volt must have 10 times that (would love the wiring diagrams/schematics for one of them!) I just want to learn for my own knowledge, and to better understand modern cars. Thanks for any advice!
