Hi all, been following the forum for a while, thanks for all the tips/tricks!

I have a 2006 Rancher TRX400FGA, and after my last oil change, I was unable to reset the oil change light. I did the normal hold the Odo and Clock buttons at the same time for 3+ sec, to no avail. I’ve tried it many times under many conditions for various lengths of time – notta.

Could this be a sensor issue? If so, what sensor? Thanks!
