I am getting the intermittent “Service ABS system” and “ Service electronic braking system” on my display.
I have had this issue before, and the dealership replaced the HCU, and all has been good for the past 40k miles or so.
I think is likely the HCU again since they are problematic on the 2018-year model.
The last time this happened, my truck was under warranty and not deleted/tuned.
A few questions I have:
Has RAM developed a better part that will not cause this issue again?
I am still unsure what I can and cannot unplug to run the truck with the MM3.
If I take it to the dealership and get them to run a complete system scan to diagnose this issue, and they unplug the MM3 from the OBD plug, what should I ensure they do or do not do so that nothing gets messed up?
