I wired up aftermarket turn signals and when I put things back together, the turn signals and high beam switch are not functioning. Is there a fuse for these? I can not find any documentation on it. Maybe a fried Relay SW? Ideas?

Which R18 Model are you trying to catch fire 🔥 to...?


Below is the TC Owners manual:

It showed the warning light but I had no way of seeing the codes. I gave up and took it to tue dealer. Turns out it was just a loose connector
 
I didn't want to ask if the lights were plugged in; it probably, would have come across as being a smart ass...

Now we know.. glad you got it sorted out; I have parts arriving from Germany and there is a bunch of electrical work that is going to be needed in order to get the rear lights working... I'll double check my fitted connectors.

Just my 2¢ ... do yourself a favor and buy a HexCode GS-911 ... it really comes in handy for many things ECU/CanBus related ... it is not cheap ... but, what on these bikes is!

Agreed... It pays for itself after two 6,000 miles service appointments at the dealership...
