Have you done anything to the bike recently ? Give the bike a once over, including battery terminals. If all good then it's possible the light will go off after 3 full heat cycles. Make sure engine is stone cold then run till fan kicks in. Do it three times and make sure it's stone cold in between. Unfortunately this will take a while.
If it clears during 4th heat cycle then all good, if not then it's probably back to dealer for them to check any fault codes (unless you can do it).
