When changing from incandescent to LED turn signals, the indicator light may flash fast.
Synchronization some Led turn lights, proceed as follows :
Pressing Hazard switch. The BCM ignores the first 8 hazard flashes and next 8 hazard flashes the BCM learns. After 16 hazard flashes are updated in the BCM.
If this process is not successful, try the following process:
Turn Ignition on, but do not start the bike.
Turn on 4 way hazards by pressing the hazard button on the controls.
Turn the Ignition off letting hazards run. If the bike has security they will flash 5 or 6 times and then pause. This is normal. They will go back to flashing normal hazard mode.
Let hazards run 1-2 minutes.
Turn Ignition back on.
Turn off hazards.
Turn Ignition off and then back on.
Check function of both turn signals.
