Default BCM Error code b2151h

Good morning All,
I keep getting this error code on the BCM "b2151h".
I keep clearing it and it comes back. I've done the turn bike on, turn on 4 ways, turn bike off let 4 ways run for 2 minutes, several times.
Lights are working fine, any thoughts?
2022 Roadglide Special, Installed Custom Dynamics LED's in January and F47 Handlebars a month ago.
Only realized I had an error after changing bars, never thought to check after installing CD LED's.
TIA

Left turn signal open, probably a bad wire, could be pinched in clam shell.

Did you figure it out? I had to get new bar wires and now getting this code a few days later.

I think you may have to have the dealer flash the new lights to let the system know they are LEDs.

'h' means it's historic, so cleared itself up. In other words, it's something brief and intermittent. This suggests something like a loose bulb or oxidized socket, or loose or oxidized connector.
