P0AA6 Hybrid/EV Battery Voltage System Isolation Fault

Hi fellow Focus EVers! My 2012 FFE has given me the dreaded Stop Safely Now message and won't start. FORScan shows: ===BECM DTC P0AA6:00-C8=== Code: P0AA6 - Hybrid/EV Battery Voltage System Isolation Fault Status: - Previously Set DTC - Not Present at Time of Request - Malfunction Indicator Lamp is ...

Re: AT&T sunset and MyFordMobile app

None of them seem to be listed as TCU or TCM, but there is a " Cellphone passport module ", fuse F1, rating 5A, located in the Luggage Compartment Fuse Box , which sounds suspiciously like it might be the one? Could anyone verify whether it sounds like I've got the correct fuse to pull? Y...

Re: It's time to free our data! Open Garages/ffpass

If we were to set up our own data interface - a cheap LTE device that listens for text messages - we could have something in the CANBus spit out whatever commands we like and sidestep everything Ford does with their TCU. Want the door to unlock? Forget the API, I'll make it think I hit the unlock b...

It's time to free our data! Open Garages/ffpass

Ford has given me no option to upgrade my 2012 FFE's TCU from 3G to 4G and so I've been kicked to the curb. Needless to say, I'm pissed at Ford's disregard for customer service. So now that I'm locked out. what is there to do? Could this be a blessing in disguise? A 3G modem isn't magic. APIs aren't...

Re: AT&T sunset and MyFordMobile app

My tech has opened a case with Corporate to get them to answer why older Fords are not supported. Perhaps if enough of us raise a stink Ford will reconsider? I mean, there goes any resale value of my Ford, right? Here's Ford's official answer. TL;DR I'm SOL. :( "Unfortunately, this vehicle is ...

Re: AT&T sunset and MyFordMobile app

It's not just a change in cell network. Ford gets to choose which vehicles can connect to which apps. It's entirely possible that your car could see the modem, make the connection and have the app go "That VIN? Never heard of it". But really it seems that there is something in the config ...

Re: AT&T sunset and MyFordMobile app

I see the TCU has a UART port. Anyone sniffed this for anything interesting? Heima's Post on the prior page of this forum at Sun Feb 06, 2022 6:24 pm has a link to the user manual, User-Manual-2224183.pdf, for the replacement TCU. On page 10 it shows connecting the unit to a pc and using a windows ...

Re: AT&T sunset and MyFordMobile app

Just tried to get the 4G upgrade kit ordered from my Ford dealer for my 2012 and 2013 FFEs. The tech is scratching his head over this (they do this a lot when it comes to servicing my EVs). He tells me there is only an upgrade for 2015 and later Fords. So, what am I to do? It has been great using MF...
