Put the key in and turn off and on three times rapidly without actually starting the engine and the milage display will give you the codes ..

 

ok thank you

If you're wanting to check the codes on your 2005 3500, it won't work like that. The check with the key only works on OBD I. I think 1997 was the first year for OBD II on diesels and '96 was the first year for a gas. Autozone and other stores will read your code for you. You can get your own reader. The cheapest I've seen is $50 at Autozone and you can easily go up to $250 or more, depending on what you want to do with the reader.

 

Some do, some don't for some reason. My buddy's truck is an 07.5, it won't, but my wife's is an 08 (gasser) it will.

Sometimes you have to turn the key 4x before it will do it.

 

My 05 will do it with the 3 quick cycles of the ingnition. If there are no codes present it simply states "Done"

 

X2 for mine.

 

well i will let yall know when i get the chance to do it to my 05 i did it to my mom's 07 3500 megacab and it worked she had no codes it just flashed done.
