Default 2009 FLHTCU Lights Electrical issues

Hello, I am having electrical issues on my 2009 Ultra Classic Electra Glide (FLHTCU). The bike has all LED lighting:
  • LX Light Headlight and Passing (auxiliary) lamps
  • Custom Dynamics Flat ProBEAM 1157 Front LED Turn Signal Inserts
  • Custom Dynamics Flat ProBEAM 1156 Rear LED Turn Signal Inserts
  • Custom Dynamics Front LED Fender Tip Light
  • Bright *** Lights 4 Super-LED Tail Light
  • Tour Pak 1157 LED Bulbs
  • Custom Dynamics GEN2-SSHD Standard Smart Signal Stabilizer
  • HD Auxiliary Brake Light/Running Light/Turn Signal Conversion Kit
All lights worked fine since installed 4 years ago. Recently, all lights randomly started to malfunction, they won’t come on or they will flash all together and then they will settle and stay on, or they won’t turn on at all. It happens more frequent now and I noticed the B1121/B1122 PN 68924-07 diagnostic errors coming up with or without the HD and CD stabilizers installed. I tested without the stabilizers, with the HD only and CD only. Same behaviors so I don’t believe the problem is with one of the stabilizer units?

I removed and checked the TSSM connections and everything seems to be connected properly

I checked all fuses did not find any blown fuse.

Ground cables are OK

Not sure what else to look for to get this problem solved. Looking forward to additional insights and guidance from the forum. I am including one video showing the problem.

Thanks for your help!

Load equalizer crapped out? Or the H-D turn/brake conversion module

Thanks for the answer, is there any practical way to test the equalizers? If I get random B1121/B1122 errors from the TSSM is that an indicator of a faulty stabilizer?

I had a Kuri load equalizer go bad and it acted like the alarm was faulty... the red key security light was always on.

I'm trying to figure out which of your lights are true LED's and in need of the equalizer to get the bike to think there is a incandescent bulb in the socket, and what bulbs are LED's with a resistor built into them so you don't need any load equalizer.

The codes are the TSSM telling you there is a fault in the left and right turn signals, I'd start at the front and work back

I replaced all regular bulbs/lights with LEDs. I just contacted Custom Dynamics requesting an RMA for the stabilizer. Hopefully I can get a new one under warranty.

UPDATE: First I have to say the customer service at Custom Dynamics is AMAZING! I spent a good amount of time on the phone troubleshooting the problem and we narrowed it down to the bike fob. The fob battery was almost dead and it seems a weak signal was messing with the TSSM. As soon as I replaced the fob battery the problem went away. So far the issue is not coming back after several days, the lights are coming on as they should. I did not know the fob with a bad battery could interfere with the bike lights.

Just got back from a 100 mile ride this morning, it was awesome weather and the bike running perfect makes the ride even better!

Cheers!
