If I let mine idle for 5-6 minutes the EPS light comes on and there is no steering assist until I put in in gear and move the machine, (or if I turn it off and restart it) then the light goes out and everything works fine. Does anyone know if that is a normal function to protect the EPS system, or something else??
Also, does anyone know the purpose of the "lean angle sensor"??

I cannot offer any advice here, I have never experience this before. I need to get my hands on a service manual...
