I recently installed a set of Autosaver88 Switchback LED Tube Headlights on my 2013 STX , these units utilize standard bulbs with a splitter that powers a led bar in addition to the OEM turn signal. Unfortunately I started to experienced the hyper-flash turn signal problem. After searching the web I learned about Forscan and changed the BCM to eliminate the hyper flash. This worked initially, but within a short period my turn signals stopped working. I got an error code: BdyCM B123A:11-0A (Short to Ground). I attempted to rule things in/out and removed the jumper/splitter for the turn signals supplied with headlights and just went back to standard bulb which solved the problem, well sorta... The new issue is my left turn signal pulses much faster than the right. Note; I did not reenable the BCM to monitor the bulbs.

I was wondering if anyone had experienced this issue and were able to solve it.

 

We had this issue and installed resistors which fixed the issue. On our other car we just bought led switchbacks with resistors built in so we werent messing with the wiring.
