CEL With A Mess Of Codes?

[AK Bob]

Try doing a load test individually on each battery.

These trucks require a lot of juice, and if you have one or both batteries with weak cell, it will throw all kinds of codes.

2016 Ram Laramie 3500, G56, 6.7, CC, 4x4

Sounds like you have a lot going on.

I agree with the advice posted above to load-test both batteries individually.

Low battery voltage at startup can cause many different codes and symptoms.

Just looking at the three codes that you were currently concerned about, they could be tuning-related.

See the attached information on those codes.

As you know, the U010E code is for the DEF System, which should already be tuned out.

The P0607 code may also be tuning related to the injector “on” time.

If the U0001 code is an active stored code, it may be a CAN BUS C issue.

I realize we have only just scratched the surface so far.

You are on the right track to start with battery condition and voltage.

Then, look for some new tuning.

Please keep us posted and let us know if you need similar information on other codes that are not resolved as you continue to troubleshoot.

I appreciate the help! I was going to buy the MM3/DRD tuning in early 2024, but maybe I'll bite the bullet and order them now.

I'll probably order the sensors now, too; worst case, I sit on those as spares.

MM3/DRD is still the recommended tuner/tuner correct?

Huh, is there another recommended tuner?

I'll order tomorrow.

The last 3 years have suuuuucked.

Oof patience?

LOL alright.

I appreciate the help!

I'll test the batteries tomorrow and order the sensors in the meantime.

I'm assuming there'll be an announcement of some sort?

I don't want to miss something.

I'm not super forum-savvy.

Yes, I will send you a link to any announcement in that regard.
