What diagnostic software and equipment to independent auto repair shops use? ?

Like when they hook your car up (bmw, mercedes, audi ect..) and it runs a diagnostics and tells them what the exact problem is and what should be fixed and how.

The BIG misconception is the diagnostics tells what exactly is wrong, it shows what system area needs to be checked further or what readings the particular sensor is seeing or reacting to . eg a cut wire will make a sensor read low or hi , ie. on a throttle position it will show no input for more fuel upon acceleration but the other sensors will try to compensate and add fuel

MAC ,Snap-on or Matco tools have scanners with the appropreat moduels
I have a Bear anylizer w/3 gas which stands about 6 ft tall and about 4ft wide about $68,000 the smaller machines will do just fine for most.
