Assistance Needed – Intermittent Failure on 2021 Ram 2500

[Luisoverlanders]

I’m experiencing an intermittent issue with my 2021 Ram 2500, and I was hoping someone could provide some guidance. Occasionally, I get a chime along with the following messages on my screen:

• Service Antilock Brake System
• Service Trailer Brake System
• Service Electronic Stability Control
• 4WD System Temporarily Unavailable

I scanned for codes, and it’s showing U010E. The issue happens inconsistently, sometimes right at startup, other times after about 30 minutes of driving, and occasionally, it doesn’t happen at all. However, it’s becoming more frequent lately.

For context, my truck is deleted and running the latest MM3 update. Is there anything you would recommend checking or adjusting to resolve this issue?

I appreciate your time and assistance.

Contact your tuner seems like the code needs to be addressed with the tune

Start by checking that all the fuses in your PDC are firmly seated.

Then hit up your tuner.

Worth checking the fuses but deleted it should not even be looking for DEF module communication. But the ABS codes should not be related to the reductant module anyway. Its a few issues in one I would be willing to guess.
