DRL LED Bar brightness boosted using Forscan

[Tyoder87]

I don't know what I'm doing wrong but I don't see any change in the brightness. I've only changed the 3's to 2's on 42-01 on the first group. I've tried all the brightness codes on 38-01, only changing the first two characters on the second group. I've tried putting it in drive to see if they brighten up then but didn't work. I enabled DRL in parking lights to see if that helps, it doesn't. I'm nor sure what I'm missing or screwing up. Anyone have ideas? Truck is a 21 XLT with quad LEDs if that helps.

UPDATE:

I got some help from Facebook. Apparently reloading my as built save and changing just the percentage codes and doing a bcm reset fixed it. Now they're nice and bright.

Howdy! Does anyone know if the same exact BCM values shared by the OP @Nightshade for his 2021 are the right ones for a 2016 Lariat with LEDs? I've tried both the 42-01 and the 38-01 changes several times and get a message "Writing block failed - incompatible configuration" message.

I had my DRLs set to Parking Light LED + Turns, so I reverted them back to Parking Light LEDs only, hoping that was the issue, but got the same error message.


Thanks!

@WestCoastHunter Those values are for 2021+ This wont work on a 2016

@antho thank you. I'll do some digging. I did notice in the first page or two of the thread that Nightshade had this working on his 2016 as well.

@antho is correct, this is only meant for 21+ F-150s. However I do have the values from the previous gen, and I’m sure the admins of this forum will let this slide for me this once but the values for 2015-2020 F-150s DRL brightened up should be:

BCM -> 726-29-02 -> x*xx xxxx xxxx (x1xx xxxx xxxx), which should look something similar to “0100 0001 005A”. Just change the * to a 1 and it should work.

—Just a disclaimer though, for the 2015-2017 F-150s sometimes have reported it doesn’t work so try with due diligence.


**Remember to back up your module before making any changes.

@Nightshade you're the man! And I was hoping I wouldn't cause any trouble given this is gen14, but I appreciate it. I'll for sure backup module, and already have my as-built saved.

I just read through all 19 pages of this thread lol. I bought a 23 XLT Powerboost F150 2 weeks ago and I am getting all the changes together that I want to make in Forscan so I only have to do it once. Its been a minute since I used Forscan (used it on my 2019 F150 some years ago). I just want to see if the general consensus is 75% for the DRL's and find out the FOR SURE changes I need to need make because I dont think the changes below are correct? So far I am wanting to change:

Disable Double honk 726-26-02: xxxx0-xxxx-xx--
LED's 726-38-01: xxxx-xxx1-xxxx

I have a feeling that I'm not understanding this correctly since it looks like there is a 726-42-01 that needs changed for the brighter LED DRL's as well?

First post and first time using forscan:



Did it today in about 2 hours total time spent on my 2021 King Ranch. I must say i am so pleased with the results!! So far no flickering but will report back if any issues. I also did bambi mode and no double honk. I used the following to set it to 75% brightness:
BCM - 726-38-01 xxxx 4Axx xx--

I did not have an HP or PC computer as ive only used Mac for school so I picked this up at best buy for about $190 and it worked great:

Before: (not the best photos my iphone 14 didn't want to pick up on the glare)

After:

So, is it possible to increase the brightness without going to max brightness? If so, can anyone come up with a table that shows approximate output with the required Forscan coding?

Here is the settings for the DRL brightness

I unfortunately lost my as built data. I’m trying to revert DRL to stock brightness. Does anyone know what those values would be? Would stock be 50% (32) or 0% (0A)?

W not just flash the 'build data' from the website...

 

[TN_Ryan]

Has anyone noticed there is not a difference in brightness with all the other settings? I tried every percentage from 100 to 10 and once you get above 10% the brightness does not change. Basically, I am not seeing a difference in 20% and 100%....anyone else?

And I can see why some guys feel full bright at night is too bright...I agree! LoL Which is why I'm trying find a middle ground...

Hi all, writing from Uruguay. I have a 2022 f150 3.5 ecoboost. Issue with my DRL. They dont work daytime (in drive, not parking brake, in motion, lights on auto). They work when i aproach the car (cortesy), when the head lights are on, but not in auto during day time. Any idea what could be?. Thanks in advance.

 

[Carnious]

I think they changed the XLT DRLs in the 24s and 25s.
changing this value I assume won’t do anything in my 2025 with the orange line DRL correct?
Or is my DRL dim as well?

@Nightshade Just wondering if this mod works on ‘25 Raptors?
