Possible they popped open tailgate cover and physically disconnected it.

At least one member here from down there.

@SilverPigeon did they neuter your rear tailgate light too?

@Mick Dundee, I've attached my BCM .abt file for you (with a .txt on the end so it would attach). Bear in mind that it is a higher trim level, but the settings you need should still be the same. Did they also disable the high mount white light? All mine are working. If you still have issues, give me your .abt and I'll deep dive it. Failing that, @HammaMan has given the extremely useful wiring diagram to chase down ?

@fordtruckman2003, my KR is a separate import from the Ford Australia imports; the compliance may well be different; all I know on that is it has compliance sign-off as being fully ADR (Australian Design Rules) compliant. ?‍ We love even more red tape down here than you guys ?

Will do......
I can test the light pretty easily.
But in all honesty, I doubt that Ford would have gone to those lengths.

I still reckon its just a line of code rather than a physical change

Silver Pigeon, just saw your reply.
Thanks mate.
I now have something to exercise my grey matter today!

There's an asbuilt comparator tool but given the fact it's the exact same wire as the 3rd brake light bed lights, you're not going to find it in the asbuilt data. The wiring diagram shows you quite specifically where to look.

I'd start by checking the connector itself, verify continuity to ground, check to see if 12v present when the upper light is on, check the diode w/ a multimeter. Also verify it's actually an LED and not a dead insert. It may simply not even be an LED. Go a page back to my wiring diagram -- it's NOT a computer related function unquestionably.

And yes to kill it could be as simple as connecting it up with power and ground swapped using 2 9v batteries outputting 18v in reverse = dead diode. Ford creates module programming boxes that they can just walk up to a truck and plug in to code 1 module w/out having to use software. A far more complex device than making a diode popper.

Here is my BdyCM .abt file (with.txt suffix added).
Thanks again

 

[Mick Dundee]

Hammaman, just read your reply. I will do as you suggest.

Hammaman, just read your reply. I will do as you suggest.

That's best Scott. As an academic exercise, your block 48 is the same as mine. The following changes are then only possible ones I can find if the wiring is fixed. I don't know if you have bed lights, but ignore those changes if not.

ExtCrtsyLght_Reg_Cfg (ECLRC)
726-30-02 xxxx xxxx x*-- 0 = ECLRC FNA, 1 = ECLRC ECE
Use 0=FNA

White_Lighting_Ckt_Cfg (WLCC)
726-50-02 xxxx xxxx x*-- 1 = WLCC DEFAULT_BACKLIGHTING
2 = WLCC ENGINE_STARTSTOP_BACKLIGHTING
3 = WLCC TRAILER
4 = WLCC BED_LAMP
Use 3=Trailer

Ext_Courtesy_Sw_Input_Cfg (ECSIC)
726-81-01 x*xx xxxx xx-- 0 = ECSIC NULL
1 = ECSIC EXT_COURTESYLAMP_SW
2 = ECSIC MAN_PUDDLE
Use 2= man puddle (unlikely without bed lamps)

Rear_Ext_Courtesy_Mode_Cfg (RECMC)
726-81-01 xxx* xxxx xx-- 0 = RECMC NULL
1 = RECMC BEDLIGHT
2 = RECMC DOWNLIGHT
3 = RECMC FLOODLIGHT
Use 1= bed light (unlikely without bed lamps, can try 2 or 3 as well)

Chris,
Thanks mate. Really appreciate your help.
I'm going to try these values anyway as it will only take 10 mins or so with a laptop.
I'm still pretty sure that ford have not been playing around inside the tailgate handle as the T30 bolts securing the trim panel that covers it do not look like they have been disturbed. Looking at the wiring diagram that Hammaman kindly posted, this seems to be the only logical place that a physical change could be achieved without it having other consequences.
So I'm going to spend 10 mins with the laptop before I pull the handle out (Don't think I will be able access what I need by only removing the cover panel).

Thanks everyone for chiming in

Scott

 

[SilverPigeon]

Don't forget that because of the wiring diagram, they could have mucked around behind the high mount stop lamp.

 

[HammaMan]

It could be accessed at any number of these 3 points quite easily and cut or over volted by simply connecting to it. Speculation on my part, but if someone asked me what's the easiest way to kill this LED not allowed to work in a market but it's on the truck, I'd just do an over-volt on it with a harness that can plug in, but not lock, and is powered by a 20v lithium drill batt or similar with a simple button and status LED that goes off when its toast.
Confirmed wiring change from models that made it to the bottom of the globe
forscan alone is enough to bring it to life.

Take C431/432 for example

Or c408

Curious to see what the final result is.

So Gents....
Problem solved!

Chris, the first two Forscan changes you gave me turned the light back on. You do need to do both and one won't fix it without the other.
I did not try the last two changes you suggested as it was already working by then so no need.

So, for any other Aussies out there that have had their light disabled by Ford, there is a very simple Forscan fix to reverse this condition.

ExtCrtsyLght_Reg_Cfg (ECLRC)
726-30-02 xxxx xxxx x*-- 0 = ECLRC FNA, 1 = ECLRC ECE
Use 0=FNA

White_Lighting_Ckt_Cfg (WLCC)
726-50-02 xxxx xxxx x*-- 1 = WLCC DEFAULT_BACKLIGHTING
2 = WLCC ENGINE_STARTSTOP_BACKLIGHTING
3 = WLCC TRAILER
4 = WLCC BED_LAMP
Use 3=Trailer

Fixes it.....

I suspect this may make more than a few Aussies pretty happy!

Thanks again gents.

Good to hear Scott. @HammaMan, this begs the question: surely the tailgate light isn't a CANBUS controlled one? Do you know if there is a slave LIN node along the path that could be doing this?

 

[fordtruckman2003]

That makes me curious if the high mount lamp was lighting up at all. Does appear both would be disabled from looking at wiring diagram.

Ford can make changes to the harness at any point -- they may have started new harnesses as a point of entering the market. I'm operating off of 22 diagrams where we've seen 23s w/ new coloring/positions. 24s are even more different. There's unused spots in the BCM for other things not included on the truck so they could have just as well used a different pin for it requiring only 1 change to the harness. Seeing the same thing in the 22 expedition with completely different door control configurations and it's a mid-cycle refresh.

They sell the F150s in china and it only required slightly different things here and there. They ended up with the coolest headlights on the raptor of any design in the 21-23 black and clear w/ white DRL -- No DOT orange reflectors / plastics

Hey Guys
I can confirm that the High Level Light was still working when the trailer assist light was disabled. If I were to change either one of the two Forscan entries that Chris gave me back to the (Ford Adjusted) As Built values, then that condition would be replicated. I am far from an expert on these tings but my reading of the wiring diagram suggests that both lights should be affected by any Forscan changes (Which is why Hammaman suggested that a physical change must have been effected). I can confirm that on MY23 XLT's (At least the vehicles finding their way Down Under) this is not the case.
Maybe as Hammaman suggests, the harness has been updated.
