Hi there.
In my st3, 2007 i have the ‘check engine’ icon on and it does not display the liquid temp. After connecting the bike to the laptop the ‘check engine’ is off and the temperature is displayed. When the wire is disconnected the errors are back.

Numbers of the errors: 115 and 120.

I think of changing the temp sensor, however when connected everything seems to be fine. I don’t know whether this would help.
Have any of You had same issues? I honestly dont know what to do...

Is the battery at full charge?

some have had issues with the earth in the ecu failing, and with the diagnostic tool connected it uses the earth through the cables and works fine. i believe you can run an earth wire into the diagnostic connector and it'll be fine. others here have done it.
