I'm having a few problems where my DEF Service message appears and disappears at random. Sometimes I get the 200 mile range and others I get a different one with less. I don't know what's going on. I took the truck to the dealer for a recent SCR catalyst recall where they replace it completely. I even when online and bought a DEF doser (injector) since the original was full of crystallized DEF. So far, the dealer gave me no answers since the warning doesn't show up with them at the dealership. I took the truck to my buddy's garage and he was able to put a $4000 Snap-on scanner to erase the codes and that DEF warning but I'm trying to find the problem. Could be a NOx sensor or something else but for now I do NOT want to "delete" the system due to health reasons. Does anyone recommend an OBDII scanner I can buy online to read, stores, and erase codes on the 2011 RAM 5500 Cab & Chassis? I'm running the 6.7 Cummins with 305HP with the EGR removed.
I was looking on Amazon at the BlueDriver LSB2 Bluetooth Pro Scan tool for around $100. I read lots of reviews about it but I would like to know if there is another scan tool out there that is not overkill or overpriced. Thanks!

I bought the alfaobd and the OBDLink MX+ on amazon. You can read codes and delete. This setup lets you do all kinds of things with your truck.

Thanks you for the suggestion. Do you have some links to share? I think the AlfaOBD is a service only as I didn't find any reader for sale on Amazon. Also, for the OBDLink MX+; did you get the black or green one? I'm getting more codes in my trucks and I need to know what is going on.

Harbor Freight...as cheap as you want, all the way up to ones that do ABS module codes.
NO WAY! Just like their jack stand towers. :ROFLMAO:
I'm not trying to be cheap but I want something that deal with the Chrysler BS software problems.

OBD2 codes are standardized. A $7 cheapo will give you the code just as well as an expensive Snap-On.

The one from HF that does ABS modules will do pretty much anything somebody needs done. The AlphaOBD setups allow for tinkering and configuration changes.

They also read codes and delete them. You can check your monitors and it'll tell you when they are reset. You can also monitor different sensors. I have mine monitoring turbo intake temp, egr temp, egt temps on sensors 1 and 2. I got the black one. Internet search alfaobd and you'll get info on what it can do. Plus with the OBD MX+, you can get all the codes and delete them. It also tells you when monitors reset.
