Change XLT parking lights to be the DRL's instead of low beams

[budpalumbo]

That is something we have to see. I always had vehicle specific scanner so this time is no different.
Mine is 2024 model though.
The problem is that if I turn the parking light on while driving, it does not turn off when engine is shut off. There can be a time when I forget about it and after couple of hours come back to no start.
Whatever, I cannot keep low beam running all the time when the lamp assly is so expensive. When I get extended warranty, it is a diff matter.

Just adding in here, I've never had a "bad" LED in the shop. What fails is either the driver module, or most often the lamps get moisture inside them (they don't get hot like halogen does) and the boards/wiring/terminals rot away. Letting them be on isn't going to end them sooner. I am not a fan of LED lighting. I would much rather put a bulb in every 8 years instead of buying a LED lamp assembly that can't be fixed. And they are cheap on the maverick. I work on euro stuff, they go over $4k regularly to fix.

I can replace led bulbs in my Elantra GT. That is how it should be in this truck too. $1200 each side on a "supposedly" cheaper truck? I don;t know if there are any aftermkt available but that is what needed

I captured what works on my 2022 XL EB here: https://www.mavericktruckclub.com/forum/threads/signal-lights-as-drls.28871/post-535584

Briefly: vehicle is started, shifted out of park, the lights go to Auto. In daylight, the front and rear parking bulbs illuminate, but the low beam bulbs stay off. In low ambient light, the low beams will turn on until sufficient light is detected then the low beams turn off.

The behavior could be described as driving off with the light switch in the “parking lamp” position without having to touch the light switch. And the low beams turn on and off as necessary by themselves.

Been working this way for about a year.

yeah this is weird - everyone else doesn’t work and it reverts back, but yours doesn’t? It’s so strange!

I finally got it to work with some slight modifications. Settings are posted below, can someone validate that they achieve the same results?

Modifications:

1. Low beam with DRL = Disabled
2. Left & Right Front Turn Lamp Usage = Turn and DRL
3. Left & Right Front DRL Usage = Disabled

Results:

1. Light off mode = No light
2. Parking lamp mode = parking lamp (dim yellow)
3. Autolamp mode:
   1. Daytime = Turn signal (bright yellow)
   2. Nighttime = Lowbeam LEDs
4. Headlight on mode = Lowbeam LEDs and turn signal (bright yellow)

Other Factors:

1. XL Hybrid
2. Recent BdyCM module update from service center for grabby-brake issue
   1. I noticed some settings changed changed in effect or options after the update

If I forget to turn off my parking lights, my '23 XLT hybrid will chime to remind me of it when I open the driver's door. does yours not behave this way?

I didn't see anything about low beams covered by the extended warranty...usually consumables like lights aren't covered.

Ah, I see. Yet more money on top of the initial expense. Thanks for reaffirming my decision to pass on buying it.

So its my first time with forscan, went in there to get familiar with it.

First I changed 'drl to include park lamps' to enable:

Next scrolled down and modified each low beam to be 'low beam only' instead of 'low beam and DRL' (do this for Left Low Beam as well as Right Low Beam):

Save configuration, and enjoy your lasfit switchbacks plus whatever else you have wired to them These come on once you put your vehicle into Drive, they won't be on in Park.

I cannot get the DRLs to remain off on my 24 XLT w/lux and copilot 360 when in Drive. Followed steps exactly but no matter what, when I shift into D the DRLs light up. I hoped to use my Lasfit switchbacks as DRLs and they are on, but so are the DRLs.

Deweyordeweynot - Follow the link in snowcat87's post above yours. As it states, he found the way and It worked for me.

One tweek, I kept my front turn's as turns only. He had them changed to Turn and DRL which makes them come on in amber. I don't know what happens when turning as he didn't include a video.

Keeping them as turn only and using DRL Include Park Lamps will light your front turn switchbacks as white. They alternate white to amber when turning.

The DRL Include Park Lamps also turns on the rear park lights. The signal doesn't separate front to rear so both will be on. I haven't found a way yet to turn them off.

When I picked mine up new just the amber turns were the DRLs. People here told me I was crazy and I was just using the parking lights. When driving in the auto light mode in the daytime the low beams weren't on, just the amber turns. I installed the switchbacks and then just had the white and not low beams. Worked that way for about a month and then it did an update and the low beams were the DRLs. I'd prefer the switchbacks but if I could figure out how to change them they'd probably just change back to the low beams with the next update.

It's too bad you weren't' able to go look at the as built data for the BCM and save it/write it down/take a photo so we could know how it was coded

For anyone wondering I tried separating the splice for the low beam and drl in the harness (as if I was going to do lariat headlights and add in the led drl pin). It didn't work. At least I have a drl wire right at the plug now.

Fyi for anyone looking to separate the drl and headlight splice: the driver side splice is just above the white plastic nylon plug thingy that goes into the headlight housing and before the turn signal harness splits.

The passenger side splice however is WAY lower down, even before the harness splits to some other plug I think for AC. The passenger splice is just behind where a plastic loom starts resting on top of the body. If you bend the harness you should feel a place where it gets much more rigid - that's the splice.

See my write up on this. I did it and made a step by step write up. You need to modify some things in forscan too.

Here is the link to my article, it’s everything you’ll need.
