The problem is that to troubleshoot and repair a circuit board often you need to supply special signals that come from other boards. You also need to confirm that signals from the board under test work properly on other boards. This is what the special test jigs did at the factory. End result is that very likely the only way to repair a circuit board today is for it to be installed in a car with things like the traction motors disconnected. Again, this can be done but not in a classroom setting.
