DRL LED Bar brightness boosted using Forscan

[abd79]

@abd79 Have you checked to see if your fuses are properly seated all the way? Someone had a light flickering on a new 2022 and found the fuse wasnt seated all the way. Seating it all the way seemed to fix it.

Which set was the culprit? Passenger side foot well, under hood or both?

Checked both and found the passenger side foot well all good. Under the hood however I could push every single one of them including the relays in by 1/16th of an inch. I’ll see what happens if I go back to 75% duty cycle when I get back from my 2 day road trip.

Hi everyone, I just joined this forum based on this thread. I did the OEM halogen to LED conversion on my 2022 super duty and my BdyCM formatting appears to be the same as for the F150s this model year.

So I changed my brightness to 75% by entering 4B at line 726-38-01.

My observation is that all settings above 10% for the dim duty cycle appear to default to 100% maxed out DRL brightness — even if you set it to 75%. I’m wondering if there’s another setting we are missing here.

I would direct message @Jesse-Infotainment he might have the answer for you.

The BCM is the same part number. The firmware is different. So there can be differences in the way things react. I can try to get a 21 superduty sheet for the BCM put up. Ill talk to Livnitup.

There isnt anythign missing its a matter of how Ford does things between the platform. Also could be a different int he lamp assembly. There is a noticeable difference in the F150.

Thanks, not sure if this helps, but I have a spreadsheet right here:



And although it’s for 2017-2019, there is a tab for the 2020 format. That’s what I was going by and it seems to match my Motorcraft as built data to a T.

Anything you can dig up may be a great help. Thanks!

using FORSCAN.. does anybody know if you can have the DRL active while your headlight switch is in the “mode 1” position? TIA!

Can you please provide a link to the spreadsheet.

Yeah sorry, not sure why it embedded like that.

I think you can do this:

726-38-01 xxxx-xxx*-xxxx
0 = option A
1 = option B

Option A allows DRL in auto headlamp switch position only. Option B allows DRL in any headlamp position.

FORScan spreadsheet for 2021+ F-150 can be found here.

@antho
is this something you could help me with sir?

Anyone looking for DRL LED Bar to go from dim to full bright, this is the only FORScan mod you have to do. Works perfectly in all modes, including Bambi mode and marker mode. Stays bright all the time! Huge thanks to @Hectort713. Confirmed working in 2021 F-150 XLT, Lariat and Tremor. Other trims, comment below if working. As always, make a backup before doing this.

BCM: 726-42-01 -> x2x2 - xxxx - xxxx

------------------------------------------------------------------------------------------
**For those with flickering LED bar: (headlight or fog light); big thanks to @ROBB1 for this.

This is the alternative way of making your LED bar brighter. So far, there are reports that after doing the modification above in FORScan, some experienced issues with the LED bar flickering, either the one part of the headlight or the fog light. To fix this and achieve the almost same result, the below steps and FORScan change needs to be done:

1. Revert/restore your changes in FORScan that you did for the above change via backup that you made to restore back to factory as-built values for line - BCM: 726-42-01 -> x2x2 xxxx xx--. Make sure to write and cycle your truck on/off.

2. Go into BCM as-built once again and create a backup once more, to be safe.

3. Change the following as-built with the following values. The preferred value that has been tested as of May 2022, is 4B (75%). Change only the "**" area, and leave the rest of the values in the line the way they are as default.

726-38-01 xxxx **xx xx--

64 =100%
5A = 90%
4B =75%
32 = 50%
19 = 25%
0A =10%

3. Write to the truck and cycle the truck on/off, a few seconds apart. Enjoy!


If you have any issues, please comment in this thread or DM me.



*Do at your own risk.

What's the default code for this one? 726-38-01 xxxx **xx xx--
Didn't write it down. lol.
