If you have a Diesel HD truck - Code reader

I'm looking for a code reader that reads diesel codes. If you have a diesel truck and a code reader that works; and you like it; how about letting us know which one it is.

If you do not have direct knowledge on one that works on diesel pickups please don't tell us about ones that work on your gasser. I followed leads on another thread where folks claimed that theirs worked on all vehicles and when I tried to confirm that I never found positive evidence that they do. Diesels have manufacturer specific codes that don't appear on gasser vehicles.

I'm not going to spend $400 or $500 for one would like to find one priced more reasonably.

This;

"The common $20 reader works with my 02 diesel and the free torque app. "

Torq and the common reader off amazon works perfect on my '06 f 350 but will NOT work at all on my '99 f 250.

Forscan is good for Ford /mazda with the right apapter and a laptop.

A decent lower cost bidirectional scan tool can be found from VXDiag. IF you are windows computer savvy -this is the cheapest full feature route.

This was one of the FAQ's for the Autel 619 on Amazon:

Q: Will it read 98 dodge 2500 ram with Cummins diesel?
A: NO, the Cummins, Duramax, and Powerstroke all use ATA code sets Not OBDII, the plug in looks the same but is not the same software, It WILL read the ABS and SRS codes on your Dodge though

True? False?

The Autel AP200 can do a bunch more stuff than your typical Bluetooth scanner such as regen initiation, live data, scanning GM specific modules etc. I bought it to program keyfob remotes for my older Chevy Malibu, saved money right there, then moved it to my truck and was pleasantly surprised by how much functionality it had on the diesel.

If the engine is used in other non-MH (pickup trucks) applications most good code scanner will work. NOT true for most diesel pushers.

Edge Insight CTS2. It works primarily as an engine monitor, but will read codes and clear them too.

Thanks but look at the first reply on that thread. I checked a number of the readers mentioned and none claim to read diesel specific codes. At least the ones I checked before giving up.


it does. I had one on my 2004.5 duramax and have one on my 2015 duramax. It will read all codes that trigger are stored or pending. Basically any code reader will read codes that are stored. It gave me the code that indicated my grid heater was not working, a quick trip to the dealer and a new grid heater under warranty.

Depending on vehicle it can do other things. On GM it will read balance rates, boost, EGT, soot level, distance since regen, and a bunch more.

Now if what you are looking for is something that gives live data and will do what factory service systems do, that's another story. These systems will do more than read codes, it will check virtually ALL car systems. Foxwell scanners do that. I have one for my duramax and one for my acura. they will let you do things like lock/unlocks doors, run AC etc. etc.

Hmmm interesting. I used the one mentioned on my diesel and it seems to work, I dont have DEF and have not had Glow Plug issues. But It did tell me my MAF sensor and EGR were bad.

Maybe none, I think that brand may do CAN2. The codes that could be missing are ones for example: DEF or Glow Plugs which gas vehicles do not have. I looked at this several years ago and the only ones that read diesel codes at that time were $300 or so plus you had to buy a code pack for your truck. I think some of them came with one code pack. That has obviously changed.

A code reader reads codes. Doesn't matter if gas or diesel. I use an Auto Link AL319 for all my vehicles.
