What does Fault code B2B06 on a Ryker mean?

[Lethryx]

Hey yall, was wondering if someone with BUDS would be able to tell me what a fault code means.

The code is B2B06. I've looked through the service manual list of fault codes, but this one isn't in there.

For context: I took my 2022 Ryker Sport into the shop to get it checked cause I was getting a cylinder 3 misfire code any time I went about 75mph for more than a few minutes, but when all was said and done, the shop didn't fix the P0303 (they just replaced the sparkplug without doing any deeper diagnostics I guess). The B2B06 code starting showing up in tandem with the still-present misfire code after this.

Shops backed up pretty bad this time of year, so I was hoping one of you might know/have had experience with this sorta thing.

Thanks!
