I have encountered a weird problem on my 2008 Piaggio MP 3 400. Bike has been performing brilliantly for many years until about 3 months ago.
When I release the parking brake, the parking brake light extinguishes but the red tilt lock warning light starts flashing and the yellow tilt lock light doesn't come on at all.
I turn the bike off. Wait several seconds and turn it back on. Problem remains. Red warning light for tilt lock system flashes (no beeps) and the yellow tilt lock light won't come on. So, I ride for around 5 minutes. Stop the engine. Wait several seconds and re-start and all is good. Red tilt lock warning light extinguished and the yellow tilt lock light flashing all back to normal. But if I apply and then release the handbrake, the problem I have described above returns. Only happens when I release the handbrake.
Bike is able to be ridden. No seat sensor issues. Reservoir is full. Wheel sensors are clean. No broken or cracked wiring.
Has anyone had this happen to them and if so, how did you fix it ?
Thanks in advance.
