2020 ATAS DCT
It is so weird to know that i also have the horn problem a while ago. Then i just touched the cables on the left of the handlebar.Had my fourth stall on my 2021 ATAS DCT yesterday, about 1950 miles total on the OD. Yet again, from a stop in traffic, low throttle input, S1 Urban mode. Luckily I was shunted to left of a lane so the aggressive car behind me did not rear end me.
Every single one of my stalls has been taking off from a stop with low throttle input, or fully idle stopped in traffic.
Weirdly, shortly before that, the horn wasn't working earlier that afternoon, but did after I parked the bike, off for awhile (I'm still waiting on Helm to restock the service manual so I can look into how that's wired).
I have a case number with Honda and have asked them to read some of these threads.
