The following procedures will allow you to Sync the BCM for the new turn signal load when adding or deleting turn signal lighting on Harley Davidson models equipped with CanBUS. No Load Equalizer or Signal Stabilizer is required on these models.
After installing LED turn signals you will find BCM codes b2151. b2156 for the rear and b2141, b2146 for the front. These codes accompanied with a rapid indicator flash on the dash and a red security light. Performing this BCM turn signal sync will resolve this symptom on the following models when using BCM compliant LED's.
2011 - Current Softail models
2012 - Current Dyna models
2014 - All models except for Vrod
Syncing the BCM:
- Turn the ignition switch to the ON position, do not start the bike.
- Turn the Hazard Lights (4-Way Flashers) ON.
- Turn the ignition to the OFF position leaving the Hazard Lights flashing.
- Let the hazard Lights flash for 2 minutes.
- Turn the ignition switch to the ON position, do not start the bike.
