Mr K,
good question, I don't honestly know but will check tomorrow and get back to you. I'm afraid I don't normally mess with things like TC, ABS, trips, etc. Just ride it as it is, out of the box. I have trouble resetting the clock!
Do you think the brightness could have any effect?
Have you taken yours to a dealer yet, if so was it accepted as a warranty claim, has it been dealt with?
