I have a 2013 Expedition King Ranch, and I've found out that some codes from other vehicles work on my Expedition. For instance, I believe it was the code from a Mustang that worked to turn off the TPMS light and message in the dash. A lot of the 2015+ codes are invalid because the 2013 doesn't even have some of the modules that are listed in the spreadsheets for the 2015+. It's trial and error, so make sure you save your original data in case you need to revert back to it.
3rd gens can be modified with FORscan too, not just 15+, so I figured i’d make a thread for it for anyone to post their findings.
I unfortunately don’t have any modifications handy, but I am looking for quite a few.
My biggest two I am looking for:
-Disable hyper flash (Want LED blinkers on my Limited, don’t want those 1000 degree resistors. For some reason, Limiteds blinkers are controlled through the computer, not a flasher relay)
-Disable TPMS (Getting a fault once in awhile when I drive more than 30ish miles. I check my tire pressure religiously)
