i have a 2015 rmz450, and the s-hac switch just started flashing while the bike is running. it seems to flash in a pattern (7 slow, space, 1, space, 8 slow) i stopped paying attention after that. looking in the manual there is no info on the shac other then a ohm test. and the fi self diagnostics uses a separate fi light and battery. no time right away to do anymore testing so just running it unplugged this weekend but thought i would see if anyone has any insight on this as i have not been able to find any info online.
