LED turn signal hyperflashing

[Z3cta]

Hello and Happy Monday

I am out of ideas
I have a limited with the projector style headlight which has the led turn signals
I am getting errors for turn signal bulb to be out on both left and right . It is not the case, all working, no burned bulbs.
I am also getting the hyperflashing only at dashboard and in the side mirror blinkers
Any help would be greatly appreciated

thanks

Did you find a fix?

I have this problem with switchback LEDs I put in the park/blinkers in my quad headlights. I have AlphaOBD and have tried everything I have seen recommended here. I refuse to chop into my factory wiring harness to put in resistors. Any ideas? Are there any proven brand switchbacks that will work without issues.

Did you try an anti flicker module? It’s pretty much guaranteed to get rid of the bulb out message in the EVIC at the very least. I ran HIDs in both my 4th gen Laramies with anti flicker modules and never had any problems although the 2015 actually had a weird flicker once in a blue moon even with the factory halogen bulbs in it. Never had any issues period with the 2017. It’s worth looking into anyway if you haven’t done so.

What is an anti-flicker module?

LEDs don’t use the same amount of current as halogen bulbs so the truck thinks the bulb is out and the anti-flicker module is supposed to remedy that. Here’s a cheap example off of Amazon: SIR IUS LED H11 H9 H8 LED Canbus Decoder cancel error message fix led bulb on and off flickering problem adapter https://www.amazon.com/dp/B07S86JS73/ref=cm_sw_r_cp_api_i_9DHJSHDN4QYJG3BRF1FM?_encoding=UTF8&psc=1

That’s good to know, thanks
