I have checked countless of truck for people on the forums, and EVERY truck I look at records DTC's including my own even when the truck owner is experiencing zero issues. I would not be too concerned about any of the DTC's there with the exception of the low battery one. These are soft codes that won't trigger a CEL or cause the vehicle to go into limp mode. Why your truck is draining batteries is strange and I don't have an answer as to why that's happening. The ABS and door modules codes are just codes and not faults, so I do not see anything of concern there, either.

 

Got it. Lurking on other f150 forums it seems others were/are having the same issue and seems to be tied to a BCM update that was affecting the headlight module? Although it seems Ford pulled the bad BCM update? Not sure if you have any input on this or not. Around the same time I noticed the DRL being out is when I have android auto/bluetooth connection problems as well.

Anyway, thanks for your clarification on things, and appreciate your help.

 

Yes, I mentioned the BCM update on post #4 of this thread. The bad BCM update was pulled from FDRS and put back in there when they patched it. That update can be safely applied with FDRS now and is also available via the OTA process.

 

Thanks for the info. Is the OTA BCM update sent automatically or does it need to be requested by the dealer? I just swapped out my stock quad LED headlamps (Chrome) for the same quad LED lights from the Tremor (Black). Never had an issue with my stock ones, by the driver's side one from the Tremor is flickering a bit.

 

There is no way to tell when it will come OTA nor is there a way to force it to come via OTA. I could have sworn Ford has a TSB or SSM regarding this. Either I am wrong and they didn't, or they did and they killed it once they made the fix part of the OTA process. Without an open FSA of some kind, it will be difficult to get your dealer to do the update, but you can try.

 

Any update? I have the same truck and am having the same issue on the exact same headlight. Were you able to find any answers? Anything helps I just bought my first vehicle and this happened!

 

New member here. Long time F150 owner over the years. My 2021 Lariat just popped up with this same issue. Passenger vertical DRL lamp not lit. 65k miles. Any chance mines under warranty extension?

 

Same issue

21. 65k

I'm seeing them all over the road now with the same problem. FL. I wonder if hotter climates contribute to the LED burning out.

 

Yeah, I'm seeing them all over too, I'm in Canada, so I don't think it's temp related.

 

Yep, Happened to me last fall, about 1600.00 for the light plus installation and light alignment 2000.00 total. I probably won't get any more Lariats or above because of this. I like my truck but being retired and 65 I want less problems, no rattle roofs either. My truck is a covid built 21. But apparently all makes have problems.
