be aware we dont get the heated grip icon light up when using oir grips....but we do have that icon....
you also should see this bike icon on startup...watch and see very carefully
I suspect its an JAPAN only option as well, maybe for the oem alarm system.
if i remember its just next to the heated grip icon
edit: on this Japan spec bike I dont see it either
I can see it in the back round (doesn't lite up) on my 2014 STD. The heated grip light comes on for a second at the first turn of the key. There does seem to be a lot going on back there becides the normal stuff.
