Fuel injectors, throttle position sensor information, camshaft position sensor information, crankshaft position sensor information, spark plug timing, air fuel mixture, emissions, transmission control module, ABS control module, AC control module, I forgetting something but this should answer your question. The shop repair manuals should cover most of these repairs unless it is something Joe Shade tree mechanic shouldn't be messing with!!!
