Duramax Diagnostic Trouble Codes
Diagnostic trouble codes, we all hate having to deal with them, but they can be a useful tool when diagnosing a problem with your Duramax engine, especially if you are not very good at troubleshooting problems to start with.

Manufacturers use diagnostic trouble codes to help mechanics figure out what is going on with vehicle, even when it is not readily apparent that there is a problem.
Not all diagnostic trouble codes will make the check engine light come on,
so there could be an issue that you do not know about.
It is a good idea to purchase a hand held scanner
to check the diagnostic trouble codes periodically.
Just to make sure you do not have small issues
that can turn into larger problems later.
Almost any hand held scanner that you can buy today
will be able to read and clear the trouble codes.
Although not all of those available will tell you what they mean
However, you can also buy good programming software like EFI Live, or something like an Edge Attitude Monitor that will allow you to do that and much more.
There are several programmers out there that do it all.

Now, that you are able to scan your system to find the trouble codes,
you need to know what they mean.
Without this information, the diagnostic trouble codes will do you no good!
So, you need someone to tell you what those diagnostic trouble codes stand for.
