That should be brought in to a garage and connected to the magical scanner Diagnostic Tool. It is the plug in that tells them about everything that is good and what is acting up. Wouldn't that be a handy tool to have if it worked on humans?
It would BUT, even with the diagnostic tool for cars, sometimes multiple codes can come up. So it's not like it's a one and done. Rather, it's often do this, do that, and do the other thing and maybe the problem can finally be traced and fixed.
And you get charged for all the labor until they figure it out, and possibly some new parts you have to buy, (that may or may not have been the actual problem). So code readers can only do so much. Kinda like doctors, actually.
