Amber DRL via Forscan (and FDRS) - YES!

[A.alansari]

You need FDRS. The change in Forscan has no effect on the color.

so i will need to enter my vin to revert and do the same thing right?

Your vin will be saved in FDRS once you connect it initially. No need to enter it again. It also will detect your vin if you have the cable attached.

@Grant4514b ..... are the white version of the lights considered DRLs (daytime running lights)? I have no idea about different laws and insurance regulations in different jurisdictions.....but a couple of years ago a friend modified his BMW's DRLs and was in an accident. He ended-up with a "modified vehicle" citation, no insurance coverage and as out over 25 grand. 15 grand for vehicle damage and a agreed-upon one time payment to the other driver for "pain and suffering -" which was obviously total BS - of 10 grand. We have to be careful when "modding our vehicles" that we do not give the manufacturers or insurance companies carte blanche to deny any potential claims. His insurer told him to go to Church and thank God he had not severely injured someone or he'd be living in a tent.

so to revert I need to connect my car and run the LDCM (pmi) for both sides without doing the Gtd steps

is that right?

A lot of vehicles come with amber DRL now, including the GTD. As far as I know, white and amber are the only colors allowed for front facing lights.

That is correct

 

[Cz_Ziemniak]

Do Mustang GTD's even have a trunk?

 

[NegativeMultiplier]

No idea about that

Changing the color of lights isn't illegal, it's cool! Haha

Okay - in that event, I'd assume that the VIN is needed in order to decode as a GTD and not a regular Mustang. I could explain what the differences are and why, but that would be a lot of talk.

If anyone wants to try this, here is an (assumed) unassigned 2025 base GTD VIN that should decode just fine, with the correct aspects:

I don't know if either of the two programs are pulling build sheets from actual GTDs, but I do know that if you were to place this in a VIN decoder it comes back as a GTD. I can't stress this enough, this is explicitly and only for the purpose of fooling the program into thinking your car is a GTD!

Edit: Ran the VIN on Carfax and it comes back as "invalid". So the VIN number doesn't belong to an existing car, but it'll still decode as a GTD on the NHTSA site. That last part is what I'm assuming is needed to make this work.

Edit 2: There is another GTD VIN in the original thread for this that also comes back as "invalid" on Carfax, so assuming that also means the car doesn't actually exist it's probably not the build sheet that matters, but the fact that it decodes as a GTD.

If I remember correctly, no. The GTD's wing mounts and transaxle cooler are stuffed in there. It may open, but not for the purpose of storage.

 

[Cz_Ziemniak]

That'll explain the trunk then, probably.

 

[roket]

Do Mustang GTD's even have a trunk?

technically no, the place where the trunk would be is now dedicated to the transaxle heat exchanger, and OP's problem seems to be something to do with a change he made to the BCM or something. i have had no trunk-related issues from doing the amber DRLs

 

[Cz_Ziemniak]

Gotcha gotcha

There is no as built data on the Ford website for this vin

Yeah, I am aware. The VIN isn't assigned to a real car. The very first question I asked in this thread was if the VIN needed to be a real one (i.e, belong to an actually produced GTD), and I got an inconclusive answer. I figured I'd make up one that decodes as a GTD in case that was the only thing that mattered to ForScan and FDRS.

If you need as-built data, this VIN will not and likely will never work.

The trunk thing is strange.

When I did some changes to the DRL 2 weeks ago I rember that my trunk opened and I was like "huh? Did it open by itself or did I press accidentaly on the trunk button while the key was in my pocket. Until this day I still don't know if it was because of the changes or I pressed a button.

Just wanted to share this since he also had a trunk related thing when playing with DRL.
