Hey fellas.
I have experienced another problem with my 2014 RC 390 and before I start digging through the bike I would kindly ask for your advice.
When I start up the bike, everything is normal, but whe I ride it for about 20 minutes the check engine lights comes up for a second or two and then disappeares. Then it comes up again and starts flasing when i go over the bumps or accelerate hard. 10 minutes after this it's constantly on. I suspect faulty oil level sensor or something like that, because all fluids are up to the recomaded level and the bike seems to be running normally.
I would really appreciate your help.

Thank you and good day to all of you.

Look at the 2 pictures I placed here, try the procedure outlined.
After you retrieve the P-codes this way, search them on the internet and in the RC and Duke forums.

Probably a loose ground or loose battery connection somewhere. Start off by inspecting your battery terminals and secondly, make sure grounding points of the bike are secure and safe. Considering all the fluids are at spec and this occasional jolt induced error can be attributed to faulty ground.

Cheers!
