Hi,
I am trying to get technical information on the diagnostic port (OBD2) for a Dodge 2007 Ram 2500 6.7L diesel truck.

I specifically need to know what SAE standard is used (J2284?) And how to communicate with the truck's ECU if there is anything other than the standard needed.

I have been contracted to design diagnostic and tuning tools for this truck and a 2004 5.9L truck.

Sorry for the strange question. I have just started working in this industry and I have no engineering contacts at Dodge.

Thanks!
Do you

Hi qwk000,

The standard used for the 6.7 L is SAE J1939.
For 2004 year 5.9L model, SAE J1859 is used.

I could not find any other ways/standards of communication with the ECU in the Dodge database.

Guess that is the only way.

Thanks for the quick reply!
I figure j1939 was it for the 2007, but didn't know the 2004. Thanks for that.

On the 2007, is there anything in your database that shows what optional modes are supported by Dodge (above mode 9)? And what optional PIDs are supported?

Thanks!

The recommended scanners are StarSCAN , StarMOBILE DESKTOP CLIENT -OR- StarMOBILE STANDALONE and did not even mention any use of generic scanners.

Guess the reason you have been comissioned to do it is because there are no options available.

The data available is for Mode 6 only and I am not too sure if it is what you mean and if it is of any use for you.

Thanks again KHLow2008!

Those tables are the kind of information I need. The terminology is a little different than what I have seen in other SAE docs and Wikipedia. I have not purchased any J1939 docs yet because they are expensive (need to make sure of what I need first).

That data shows only mode $06 but I need tables for all of the supported modes (and sub-modes like the tables you gave me). It looks like you got those tables from a Mitchell repair manual. Can you recommend a specific one for me?

By the way, yeah, this is one reason why I was hired. The scanners and diag tools available are expensive. However, most importantly, they want some custom things done and this requires more in depth knowledge.

Yes, those are from and we as 2carpros technicians do have access to them.

These are online and you can subscribe to them for specific models. For more details you can try this link.

I am not sure how it goes and if you are interested to know more, I can get one of the admins to assist.

What you are doing is beyond my scope so my assistance is limited.

Good luck to you undertakings. :)

Ok, I think I will need someone's help getting the right document(s). Ondemand5. Com appears to be very expensive (about $150 per month). I was hoping there was a cheaper way to get to the document that you showed me.

I subscribed to "2007 Dodge Pickup R2500" on eautorepair. Net ($17/month) but I can't seem to find the same info. I think it may be just for do-it-yourself repair (no technical detail).

Thanks,
Wes

I am not sure but you might be looking at the package for all models and that is the reason for $150 per month. For specific models it should not be that expensive.

I will contact the admin and request Mike to provide you with more details.

I will PM him to get him to explain to you.

KHLow2008,

I think I do have the same doc as you. I searched for references to "j1939" and found the same info you gave me. Thanks for the reference.

I sent an email to SAE support to see if they can tell me anything more.

Thanks for everything!
Wes
