the blinking twice is a fail code. in this case code 2. when anything with the ESP fails it will cease to shift electricaly. The code two pertains to the up/down shift buttons and its harness. typically this code come up after the atv has been very wet, whether it be from heavy mud and ect. or more typically powerwashing the atv. that switch assembly has a harness that runs up under the front fender to a large gray connector. i would get to that connector and disconnect it, then check for moisture. this is typically where you would find water if there is any. you can blow that connector out with comrpessed air, as well as the harness. if this doesnt cure your code two then there is a short in the harness. one from a 2001 may work if that is the case.
how do i find out what the codes are?
