Will loading factory AB file calibrate a new headlight module?

[adrencg]

I had to buy a new module for a signature headlight, but it appears to not be configured out of the box.

The headlight which had a module already intact when I bought it works fine. The one with the new module is not working properly. If I get the factory AB file from Ford and install that using FORSCAN, will it get the both headlights working uniformly?

Hmm I just did an as built backup and lost my keypad functionality. If you haven’t changed or added much heck give it a try. I think you’d want the bcm section you shouldn’t have to restore the entire thing.

There's also the list I could work from and put the correct values into the headlight sections manually in Forscan. But which addresses cover headlights and DRL? I know that these are in there:
726-42-1
726-42-2

Possibly 43 also

How can I find out where all of the others are? It can't be just the two I listed.

In the end I may just reset everything back to factory to finally get this headlight working. I had only changed Auto Start/Stop, Double Honk and my tire circumference. I can always just go back in and change those again.

ehhh...didn't work to reset the BodyCm as built back to factory. The driver side light will still not behave like the passenger side (which works correctly).

I know that both headlights work because I have put the working control module in both. Maybe Ford service has more advanced tool to make the left control module programmed identical to the right. I have an appointment in a few days and will find out.

So come to find out from the parts dealer that the module needs to be flashed before it can write new values. My Ford service appointment should straighten that out.

Note to anyone who buys signature headlights from Ebay. Pay the extra money for a headlight with the control module.
