Just so you know- if you have a check engine light illuminated, that means there is a fault in the engine module or abs module. When you are connected to the body computer with AlfaOBD, and you scan for faults, you are ONLY scanning the BCM. That’s why you only saw a few “B” faults that had to do with lighting, which don’t set off a check engine light.
You need to connect to each individual module one at a time, and scan each one for faults. Start with the engine module.
And there were at one time three of the 'B' fault and when I click on one of them to take that one out it took all of them out the same time but I haven't recheck it to see if there were any others ones.

Don’t connect to the body computer to scan for faults. Those faults in the body computer are not causing the check engine light. You need to connect to the engine and read those faults.

Okay today I went to that menu like you mention and I had three code or faults it was P2509, P0501 and U1412 I was able to clear all of them but the U1412 fault, I did try two times but it's still there. I clear the faults last night and I disconnect the Neg. battery and left it up hook all night hoping that it would reset itself.

It's still there but I will keep trying until I take it back to the dealer Tuesday but by Monday I will take out my bypass cable and put it back when they get done.

Implausible wheel speed.
Now, connect to the ABS module and scan that for faults. Clear those, then go back to engine and try to clear that fault again.

Okay so how do I connect to the ABS module, Body Computer, Car configure and then? I can go and do that right now but I want to do it right.

Oh Body Computer, dodge 2018, connect and go to the car with the open hood and clear all? Oh okay instead of going to Engine I will go to ABS and go from there?
