What trim level is your truck? And I assume you got the appropriate adapters with can bus resistors correct? I just went through a similar issue with my 2015 big horn on the drivers side.

 

My level is outdoorsman. I got the adapters with resistors from retroshop. how did you get it to work or did you not?

 

I bought mine used, and it came with used resistors. On my passenger side I had both resistors grounded through a single self tapping screw into the frame under the headlight, and the passenger side worked great. I did the same thing on the driver side and it was doing the same thing as yours, the resistors were also pretty beat up, so i got a brand new set of resistors and grounded each resistor individually with self tapping screws and I don't know if it was the new resistors that fixed the issue or the new grounding.

 

I had them grounded separate from each other to start and then grounded them together. It was causing the same issue as before. I tried 2 different sets of resistors as well and still no luck. Do you have DRL's active on your truck? im almost at the point of going back to stock if i can't figure something out. im thinking it is something with the wiring on the truck.

 

Do you remember how many resistors you had installed when you did it?

 

I have automatic lights and i have 4 resistors in total. When you get the error, did you get out and actually check if the blinker stops? I found with my truck the blinker would actually stop functioning. So then i tried running the problem light without resistors, I found without the resistors I went 3 days before i got my first error, and when i did get the error, the blinker still functioned. After that I tried a new set of resistors and regrounded each resistor individually with nice self tapping stainless steel screws.

A good friend of mine who was an electrician for a while told me that 98% of the worlds problems are caused by bad grounds... I'm inclined to believe him.

 

Ok i have 4 resistors myself. yeah i ran the truck in the drive way and turned on the turn signal and watched it blink normal for about 4 blinks then stopped. i may try and ground them out separate from each other again and see if that causes issues. Do you remember what OHM your resistors where that you put in new? i noticed that i have 50watt9ohm resistors and im wondering if that could be a problem?

 

I have these resistors: https://www.theretrofitsource.com/c...source.com/components/harnesses/morimoto-hd-load-resistors.html?preselect=50336 They seem to be the same spec as yours.

 

Thats what i am running as well. I just went and unplugged the resistors from the headlight harness and ran the lights for about 5 mins just turn signals and 5 mins parking lights with turn signal and everything looks good. no hyper flash and no error code. knock on wood that solved my issue. we will see

 

Unplugging the resistors is a temporary fix, it took about 3 days before mine started throwing an error again, but it leads me to believe you have a grounding issue with the resistors. What did you ground them to?

 

i grounded them to a factory ground

 

Where's the factory ground? I didn't see any that were close enough to use, did you make extensions?

 

I made an extension. I may have to order new resistors and see if that fixes it also and ground on the frame. I'm just wondering if 9ohm resistors are to much and I need 6 ohm

 

I'd try ditching the extensions and just ground right into the frame by the resistors first. If that doesn't work maybe explore different resistors.

 

I'll give that a shot and see if it works. I'll keep in mind the resistor swap.

 

I'm assuming on the driver side you grounded right to the battery correct? And if that one is working, definitely leave it alone, just focus on the light that's not working.

 

Did you have projectors to begin with? What bulbs do you have?

 

No the driver side is not grounded to the battery but it works just fine.

I did not have projectors on my truck to begin with I had the quad headlights.

 

Knock on wood I may have fixed it a separate ground for both resistors on the frame.

 

Awesome, got my fingers crossed for you.
