After your handlebar install you may get an error code. This can be caused due to unplugging your wires and leaving your ignition switch on. The true way to avoid this is to disconnect your battery first. But if you do get this code do not be alarmed, it is very simple to clear. We only recommend doing this after your install. DO NOT DO THIS FOR ANY OTHER CIRCUMSTANCE, IF YOU GET THIS CODE TAKE YOUR BIKE TO HARLEY DAVIDSON.
