Turned out to be a pinched ground wire in the loom. The dealer spliced in a replacement wire.

I got the same issue. For the front right. Like you mentioned. It was a stretched wire for me. Mine was the power wire. When I got it back the fault came up and I fixed it myself. Before I left I asked what the issue was and they mentioned that since I had risers on, that may have caused it. The tech at the dealership did a terrible job and just twisted the wire and put some type of heat shrink.

I ended up fixing it myself and added some extra wire and soldered spliced the wires. Because when you turn the bike to the left it stretches the handlebar wire especially the turn signal one. My turn signals are integrated with the handlebars.
