Like a lot of you My Ford Mobile quit working for us two weeks ago. MFM has been working fine every since the modem replacement was done back in February 2016. It can't be a coincidence that AT&T is shutting down its 2G networks and now MFM has stopped working for a lot of MFM customers.
I have a theory that when the dealer replaced the modem they took out the original 2G modem and put in another 2G modem. From talking to the service manager he did say that the way that program was carried out was highly disorganized and the techs have no idea if the replacement modems they were receiving were the new ones or just another 2G. Currently my system inforamation is showing the CPPM ENS is "UNKNOWN" so either the TCU has failed or there's no one answering its call perhaps because it's trying to phone home on a frequency where no one is listening anymore.
I am trying to find the TCU/modem in our 2016 C-Max Energi but its location seems to be a well guarded secret. Pretty sure it is in the rear of the car some place but so far I've pulled ever panel and not seeing anything that looks like what I need. I did find the keyless entry model in the rear behind a panel on the left side of the interior but I don't think that is also the TCU?
Does anyone know where the TCU is and what it looks like?
