I just noticed that the LED strips in my 2014 GT headlights stopped working when the headlights are in AUTO mode. They work fine when the parking lights are on and when I lock/ unlock the car, but they don't turn on in AUTO mode like they used to. Any ideas? Thanks
Are you sure the DRLs (they are actually called "signatures" on this lamp, not DRLs) are supposed to be on in "Auto" mode? They may not be required by regulation and therefore with "Automatic" switch engaged, they do not come on?
If they ARE supposed to be on with "Auto" engaged, I would think it's an ECU or BCM issue if both lamps are affected.
@BlackBarchetta... I think I’m going crazy now but I could have sworn that they were always on in the past. Every other mustang (2013-2014) that I see on the road always has them on. So unless they all have the parking light on, then maybe I’m going crazy. Do your signatures stay on during the day? Thanks
Mine are always on (when running) unless the high beams are on, or unless I pull the hand brake. I’ll check it later this evening to see if the Auto setting has any effect. I never use that switch position.
I'll have to check mine tomorrow to see what it does. But what if it has something to do with the hand brake switch you mentioned? Maybe it is stuck in one position or the other? Just a thought...
So I finally figured this out. Turns out I had a few thrown codes that werent registering on my code reader. The codes did register when using FORSCAN though. The codes were B2A2B and B2A2C. Left and right corner lamp output circuit short to ground. I reset the codes and my LED strips in the headlights work again.
