DRL as Turn Signal at 100% - No Low Beam - Working. (XL/XLT)

[snowcatxx87]

Quick aside: There is a lot of confusion on what a DRL is. A DRL is "daytime running light." It doesn't have to be its own light (think lariat), a DRL can be a signal, a low beam, a high beam at 50% (like some vehicles, but I hate that - so blinding haha). In Canada, we do not have the DRL menu in the dash, and our DRLS happen to be the lowbeam and signal lamps at 50%. Forscan/Ford refers to DRL both ways, an actual light, and something being used as a DRL. We don’t have lariats, so no need to change anything actual light related.

Outcome: Turn signals to be at 100% brightness for DRL.

My Vehicle: 22 XLT Hybrid Mav, Canadian Spec, latest software from dealer as of Feb 2024 as it has so many darn recalls, I feel like a letter comes a month.

I made a new thread because the old thread is 2 years old and it is derailed by arguing about LED lifespan and warranty. Thanks to everyone in that thread that contributed, I went through everyone's posts over the past year and decided tonight I was finally going to crack it. I spent hours going back and forth on settings.

If you want to do this in your garage, the ambient light sensor is the black nub on your dashboard. I used a flashlight to force it into day mode, and then covered with my hands for 10-20 seconds (depends on what you have your mav set to) to make it go to night mode. You can test your results without having to go in and out of your garage or test at nightime etc.

Forscan:

I had a lot of weird anomolies with my truck, causing it do weird things, so go through every setting carefully. What I found to cause mine not to work was the high beam said not used for one side, and "power supply" for the right side? This was really weird. I also had all my "DRL by autolamps" disabled as well.

Below are my settings to get this to finally work, and I checked after a bunch of cycles:

To get signals to be 100% brightness you have to change Left Front Turn Lamp Usage and Right Front Turn Lamp Usage. - Turn and DRL

LEFT

RIGHT

LOW

DRL

This might be the winner.

So your indicators just run at 100% all the time? Even with the headlights on? When one is being used to indicate the other is static at 100%? Even if the amber is not 100% with the headlights on, was it on at all before?

Indicators are on 24/7 in stock form, even with headlamps. Nothing changed there.

I just turned off low beam for DRL. Indicators still flash, other is static at 100%

it wouldn’t be safe going around with turn signals at 50% in the day, they are so dim - that’s why ford brightens them up

Good work! I'm sure it will be the same, but I'll wait for someone to successfully do this with a USA ecoboost before I try it. Should be the same tho...

It’s the same.

When I picked up my new XLT in November only the turns were on when in drive acting as the DRLs, no low beams. People told me I was crazy. It stayed that way until an update a couple months later when it went to just the low beams.

I have a US XLT Ecoboost and followed snowcatxx87's changes with the exception of Left/Right Turn Signal Usage. I have Switchback front turn signals and left the both as Turn Only. I wanted the low beams OFF with the white of the Switchbacks being my DRL's. This is exactly what I got with the changes.

I know that the lights don't look bright enough but I think this was just because my camera was looking up. I did drive to a storefront glass and the lights are plenty bright enough.

Things I noted in my process.

All my DRL's by Autolamps were already enabled, but my DRL include Parking Lamps was disabled. Another one was Using Low Beam with DRL. Both of these were not addressed in the original post. I know that I enabled the first and disabled the second during my attempt to get this working.

I also had the RIght/Left Front High Beam Usage set to "not used" (left) and "power supply" (right). I was a little concerned with changing these since are set as they are and didn't appear relate to the low beams. I went back and changed both back to their original settings and tried the other options. All selections except "High Beam" for both made my low beams flicker instead of going OFF. Since one of the settings that didn't work for the was "Auto High Beam", I hope it doesn't interfere with the Auto High Beam feature..

Makes sense about the DRL by autolamp, US vehicle - we do not have that enabled or the in dash setting to turn on/off DRL (I have it coded now, however)

Using low beam with DRL is under the DRL section, check op.

Yes, I am not sure why the left and right high beams are weird in forscan - but this was the trick I found to get this to work, perhaps the vehicle needs something to high beams to allow each function to work? But after trying everything, this was the aha moment and I couldn't believe it worked. I will test auto highbeams tonight as I am going out for dinner.

You sure you dont want to try full beans to the signals? makes your white brighter too!

Sorry snowcatxx87. I meant that this was missing in the OP of the original thread that started this. Guess I need to make sure I'm clear.

Full beans?? Anyway, changing my turn signals to Turn and DLS made my lights amber at 100%. They never turned to white. Using the DSL include Parking Lamps added the switchback to the DLS lights in white. That part I got. Just needed the missing pieces to get the low beams off.

Ahh, that is how the switch back works - the low voltage keeps it white, and full voltage it goes amber. Makes sense, I've never used one or seen one in person.

Auto high beams work just fine

 

[24atlasmaverick]

Ok, I’m doing a different project but your info may help me! What parameter actually turned off the low beam for DRL? Was it “Using Low Beam with DRL”???

What project are you doing? This was unsolved since forscan came out with support for Maverick - it was everything listed in my first post to get it work properly without resetting itself after one key cycle.

I am trying to get lariat headlights working on my XLT. Can’t get the top LED to light up. I already wired it up, but no luck!
