How To Synchronize Your Harley® LED Turn Signals

How to preform a Turn Signal Sync

Welcome to the world of motorcycle LED lighting!

Harley-Davidson® motorcycles equipped with incandescent turn signal light bulbs that have been replaced with LED turn signals will need to perform one of these turn signal sync processes below. Doing this sync process will allow your new HOGWORKZ® turn signals to function properly. 

2014 and newer models with canbus / BCM electrical systems:

  1. Turn the Ignition on, but do not start the bike
  2. Turn on your 4 way hazards by pressing the hazard button on the controls
  3. Turn the Ignition off letting hazards run. If the bike has security they will flash 5 or 6 times and then pause. This is expected. They will go back to flashing normal hazard mode
  4. Let hazards run 1-2 minutes
  5. Turn the ignition back on
  6. Turn the ignition off and then back on
  7. Check the function of both turn signals

2001-2016 models equipped with a TSSM  (Turn Signal Security Module) and are non-canbus / BCM

  1. Turn the ignition on, but do not start the bike.
  2. Turn on the RIGHT side turn signal and let it flash 2 times
  3. Turn on the LEFT side turn signal and let it flash 2 times
  4. Turn on the RIGHT side turn signal again and let flash a minimum of 10 times
  5. Turn on the LEFT side turn signal again and let flash a minimum of 10 times
  6. Turn the ignition key off and then back on.
  7. Check the function of the turn signals
  8. Thanks for riding with HOGWORKZ!
