Codes indicate a short somewhere in your high beam circuit.
You will need a H-D Service Manual that has the wiring diagram, along with the Electrical Diagnosis manual.
Your Bike has the CANBUS system so it could be in the handle bar switch, the headlight circuit or BCM depending.
What part of PA are you in?
Good luck doing it yourself without a H-D Digital Technician.
Let us know how it works out for you.

OP; Electrical gremlins can be hard to trace. Those codes (U0142 = Lost comm w/RHCM & B2133 = High beam output shorted low) seem to be related to handlebar wiring so...any recent bar mods/upgrades you need to add to this mix (e.g. grips, bar swap, controls, etc.)?
Either way, take the earlier advice, get off your high-horse & go to a dealer before you f--k up the bike even worse then get stranded. Especially since this is you sole mode of transportation.

The BCM is detecting the problem. The nice thing is the BCM protects itself instead of a fuse blowing.
Looking at the fault yourself though the simplest place for a short in the wiring is where it enters the headlamp shell or in the shell itself.
Anyway get a dealer to fix it under warranty because if it is a break in the wiring loom the whole thing will be probably be changed instead of just insulating a single wire.

Thnx for the replies. I was told before that if they don't do the oil change at the 1000k mark and check everything, the warranty was voided. I'm not here to bad mouth any establishment, there's no point of putting that energy out in the air. Sometimes things happen. Thats life you deal with it but try and find your balance( just like the road). The only thing I did was add a sissy bar, changed the oil, transmission, filter, primary chaincase. Haven't touched electrics at all on the bike. To be honest only thing I ever did was on my vulcan( sold it) . During the pandemic I installed exhaust, air flow, wiring back turn signals, changing the front light to a led, rewiring when installing the power commander, and downloading different mapping systems for the bike. Been riding for 6 years. But I will maybe ponder on the idea of a different dealer. Just been working. 🙃
