Dammit - trouble codes

[RedOregon]

Just had the check engine light pop up...
U2087
U2067
U0121

then part number 002606-01

Sure would be nice to have a FULL trouble code list out there somewhere! Can't find that part number either.

Sigh... time to go start looking for loose ground or battery cables... once she cools off! 2024 Tri Glide.

I keep the fuelmotousa.com HD trouble codes bookmarked in the browser on my phone. These things always seem to pop up when your three states away. Very handy and useful info to be able to refer to.

Take it back to the dealer and let them figure it out unless you have done something to void your warranty.

Hey Red!

Sorry to hear about that. Those all seem to be CanBus communication codes. the U0121 is "Lost Communication with ABS"
U2067 ABS EHCU INITIALIZATION FAILED (no vehicle pwr or lost comms diagnostics)

U2087 ABS EHCU MESSAGE LOSS FAULT (no vehicle pwr or lost comms diagnostics)

I would go look at all the connectors to do with your ABS and all Brake connectors....starting at each wheel and going all the way back to under your right side side cover.

Unplug them and put some dielectric grease on the connectors, then plug them back up really good. Dielectric grease on every connector is always a good idea.

Hopefully you do not have a reoccurrence. If you do, then it may be time to get it on the digital technician at a Dealership.

Computers on these newer models give convenience, but also have some downsides. Your 2024 Tri Glide is not as loaded with computers as the new VVT models in the video below, but they still have dozens of connectors, a few computers, and over 1 mile of wire.

So yeah, she was due for a three holer anyway, and she's only about nine months old, so off to the service department. (I have a lift and do all my fluid changes normally, but we won't talk about my back right now)

The codes were historical and they couldn't force them to reproduce on a ride, but the guy running the shop knows his feces and ran it all down. I'll repeat as best I remember for educational purposes.

He said normally when you get a whole fistful of codes and the dash lights up like a Christmas tree, it's usually not a whole bunch of things breaking simultaneously, but rather a communication error across the CANBUS.

First culprit to check: battery. Low or flaky battery will screw comms every time. Mine was great.

He said on trikes they've seen problems with the wiring harness several times now. Unfortunately, several times he's seen it happen once, then never again.

So they cleared the codes, logged them on the ticket, and said if it ever happens again to just bring it straight in, no appointment or anything else. They can pull the codes and get with ?Tech central? or something like that at the MoCo and get them to authorize the wiring harness replacement.

Glad she's well in warranty!
