Hi all,

I have a 2011 RAM 2500 diesel 4wd - engine light just came on at 69K. Can I read codes w/o OBD? If so, how? Thank you in advance.

 

Prolly better answered in the diesel section of the forums.

 

Moved to Diesel

 

key on - off - on - off - on quickly and leave on without starting the truck. codes should display on the odometer. That's how we do it on the 2nd gen 24v's. I don't think Dodge ever changed that method.

should say P-done when it is finished displaying codes.

 

Just go to any napa/oreillys/carquest/autozone/etc and borrow their code reader.

 

You sure about that...???... had a friend try all those places and they couldnt get into the computor to read the codes on his 2011 ram. We even tried my 2010 and they couldnt get into mine either. Likely chrysler has them locked out now... FORCING you against your will to go back to the dealer so that they can charge you. (which is wrong, VERY wrong...!)

 

Yes, they spend 10s of millions of dollars developing special scan tool protocols and software for Diesels only.....just so a dealer can get more cash. Makes perfect sense to me. I'm sure they have nothing better to do with their time.

 

I have a general code reader. I have no issues getting codes.

 

My home scanner is the same one that Oreilly's loans out, and I haven't had an issue pulling any generic OBD2 codes. That's the neat thing about a government mandated industry standard. Any OBD2 compatible scanner will be able to pull the generic OBD codes. If you have BCM, ICP, TCM, SRS, ABS, or other module codes the OBD2 scanners won't be able to read those, but you should still see a MIL request code indicating a trouble in the subsystem.

I can't see much in the way of live data on my 98, but then again there isn't much data available on a 12 valve.

 

You only say that because YOU work for a dealership Randy.
Most people prefer NOT to go to the dealer if they can help it.
