DRL LED Bar brightness boosted using Forscan

[abd79]

@abd79
You still have flickering?

Nope, completely gone with the lower setting. Lower setting doesn’t seem to affect light output either.

i have flickering after adding this mod months ago. I believe I did the original that was 100% brightness and now I want to lower that value to stop the flicker but Still brighter than stock. Based on the spreadsheet how do the values work? Is it just 60%, 75% or 100% brightness or can you enter values in between? Not sure how the values work if I want to try say 70%

The DRL were made for others to see you, not as driving lights. They work great for the intended purpose day or night. When you brighten them up you have no regulars for other drivers, just like the ones that put all these LED lights on their vehicles. Some people are bothered by the glare even during the daytime. It’s the same as leveling your truck without adjusting your headlights, because YOU can see better. Please, have consideration for other drivers.

Hey guys, just completed this mod this evening..... I changed the ** to 3C for 726-38-01 xxxx **xx xx-- I think i want to dial back the brightness, but I am not seeing values for anything less than 60%. Any help would be appreciated.

Is hex to dec conversion. You can make it whatever you want ..

So find a dec to hex conversion


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

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

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.

Thanks all and is there a way to boost the brightness for the amber light inside the headlights?

Not at this time. They’re usually bright when the sensor kicks in or when it’s on. Ford did a good job with that part.

I just posted this in a threat, trying to get help:

I changed up the DRL setting using forscan. I used the below changes

BCM

726-38-01

xxxx

**xx

xx--

TO

BCM

726-38-01

xxxx

32xx

xx--

My question is - no matter what hex/setting i put they look the the same brightness, much brighter than stock but really bright no matter what setting in forscan. Second - my approach / welcome lights no longer work when i approach my truck - also when I open the doors the interior lights dont come on. Any input on this issue? I set the value back to stock and the welcome lights and interior lights still arent coming on.

@Random155

I would load your factory asbuilt back and see if all functions come back. Have you made any other BCM changes?

No other BCM changes. I am getting the "system off to save battery" message now on my sceen. Do you think messing around with forscan today drained the battery and the truck knows this and wont turn on the welcome lights to conserve battery?

Remote unlock / lock and start also NOT working on ford pass app.
