When it comes down to it there is very little involved with the computer when repairing a car. Now there are just some wires to disconnect each with a proprietary plug so you can't switch them accidentally. All the computerized stuff will just let you know which part to replace with a very simple reader. Otherwise everything is replaced the same old way. With the exception of using metric tools.
Heck I've looked in the engine compartment of some new cars. The technology has refined so much that they are much simpler to work on than cars from the 80's and 90's. Those cars were a cluster f**k of wires, hoses and vacuum lines all tightly packed together. Requiring you to disassemble half the engine just to replace a power steering pump.
It's not like having to navigate a computer interface at home. You just plug in a scanner, press a button and get an error code you can look up in a book. Fancier models will tell you what the error code means.
