there is no serial number on 59m , you can make everything without licence.
if the tps reset is not working , it's not because the button isn't enabled , it's because the reset is maybe not electronic , but mechanic if your tps can adjusted by unlosing the screen on his body

Hi everyone, looking for some insight on a TPS reset issue I’m having.
I’m trying to reset the TPS, but I’m not seeing the values change after the command. The software isn't greyed out, and it accepts the 'Reset' click, but the value stays fixed at 0.7° when the target should be approximately 2.3°.
My procedure so far:
Bike at operating temp (tried both 60°C and 70°C).
Ignition ON, engine OFF (also attempted with engine running just in case).
Kill switch in 'RUN' position.
Confirmed no active fault codes in the ECU.
Even after clicking reset, the 0.7° reading remains static. I'm trying to avoid digging the spanners out for a manual physical adjustment if I can get the electronic reset to work.
Am I missing a specific step in the JPDiag sequence to make the ECU 'save' the new baseline? Or does the 0.7° reading suggest a physical stop issue that the software can't override?
Any advice before I go the manual route would be appreciated!"

Tried the reset with JPDiag at 70°C. The button is active, but clicking it doesn't change the value—it stays stuck at 0.7° instead of jumping to the 2.3° target. It seems the ECU is accepting the reset but the physical butterflies are sitting at 0.7°. Is the consensus that I need to manually back off the idle screw to find 'true zero' (0.0°) in the software first, then wind it back up to 2.3°?"

the temp is only for trimmer
tps is engine off ,no need to warm it , just take care you are not putling on cable letting the front wheel straight

you can't rotate TPS ??
