I solved vitpilen and svartpilen's can HLU fail

[yun su]

I often saw can HLU fail.
It was disconnected wire problem.
Soldering was not very perfect. I was not satisfied. So I soldered it again.
Now, perfectly work.

good luck guys. Headlight unit is very expensive. fix it yourself.

There is a guy on the 401 forum that would be interested to know how u got to expose the circuit board....the 401 and 701 look different but any tips u give him might help.

Thread '2021 Dashboard Disassembly'

Hi folks,

I am trying to disassembly the circular instrument cluster on a 2021 svart. I've been having issues with the backlight flickering and, as time goes on, it just being on in general. At this point, it only turns on for a second when I give the unit a smack.

I took the unit off the bike and removed the clear and rear casings. I am at an impasse though. From what I can tell, the only thing holding the board down now is the wiring harness. Now, accessing that would require me to break the seal around the rubber rectangle and pull it out. I tried doing this, but the glue/epoxy is...

사진 고맙네요.
401 포럼에 회로 기판을 노출하는 방법을 궁금해하는 사람이 있어요. 401과 701은 달라 보이지만, 당신이 주는 팁이 도움이 될 수도 있을 거예요.

Actually, I don't know how to disassembly the cluster.. that picture was disassembly of Headlight Unit.
