Thanks jpohlman. How do i delete the post here ?

You'll probably have better luck on the cyanlabs site

Where to start..... I'm in the UK and 3 months ago I purchased a 2020 Fiesta van which was running Sync 2.5 R5.6.6.1_R19113a Revision (R5.6.6.1_PRODUCT_GS). I updated to MB3T-14G516-ML G2.5_PRODUCT_GH Dated 19.03.2025 trying to fix the missing modem ESN. Modem part number is KT1T-14G087-EP which has been updated to latest FW with Forscan. Forscan shows B156D:55-48 “TCU Customer Connectivity Settings Synchronisation With HMI" so the TCU is not talking to the ACM. The TCU shows good signal and waiting for authorisation in Forscan. In the time I have been fighting with this I have bought 3 other modems and another ACM. All the original kit is currently in the vehicle. My knowledge is very limited to say the least but would there be any suggestions ? ------------------------------------------------------------------------------------------------------------------------------- Edit: Posting only for the purpose that it may help a future commercial vehicle owner. Information may not be correct but it's the conclusion I have at the moment and I do hope it's a conclusion. After 2 months of changing modems and ACM units, pulling the van apart, endless phone calls to FordPass, posting in several other forums, flashing TCU firmware's and changing values with Forscan... The van is equipped and wired for Ford Pro Telematics for fleet vehicles and will not work with FordPass. Sync 2.5 without APIM module simply does not have the software hooks to talk to a FordPass‑type TCU, so the ESN field will always be blank. It’s a fleet telematics TCU, used on Transit, Fiesta Van, and other commercial models. Fleet TCUs don’t integrate with Sync at all. They sit on a different CAN bus and report data to fleet systems, not to the infotainment system. The Fiesta Van architecture physically cannot display or use a FordPass modem unless you retrofit Sync 3. The KT1T‑14G087‑EP modem is a fleet-only TCU. Fleet TCU's are designed for tracking only. FordPass support were completely unaware of Ford Pro Telematics finally reporting back that they had "Never heard of it" and I think I must have talked to just about every member of the team in the months where the case had been open. Ford’s support scripts assume every “telematics” vehicle has FordPass. To Ford’s customer‑facing teams, “telematics” = “FordPass Connect”. I deeply regret disassembling much of the dash, centre console, boot trims to obtain parts numbers and check wiring. I think I must have nearly worn out the OBD port connector on the GWM. If I had the above information, correct or incorrect, it would have saved me a lot of effort. I have managed to get the van released from it's previous Ford Pro Telematics owner and I'm now in the process of creating my own fleet and registering my vehicle to it in the hope of getting Ford Pro's basic tracking and vehicle health through "Ford Pro Telematics Essentials" If you have a Fiesta commercial van with Sync 2.5 and FordPass is working please don't tell me about it. ------------------------------------------------------------------------------------------------------------------------------- Edit:  Ford now saying my vehicle is too old to use Ford Pro Telematics Essentials. There is some mention of using a PID such as the Geotab Go.      

I recently bought a 2015 Ford Focus. Only a few basics work on the sync screen and audio system. I put my VIN in the Ford sync website and it says I have Sync 1.1, v5.8. The screen shows temperature, time and date, and sometimes it shows messages about "Looking for paired phone", "phone not found, and "paired phone needed for 911 assist". If I press the CD eject button, it says there's no CD loaded. The backup camera works, but not much else. On the audio system, the buttons light up when I press the power button, but the only button that does anything is the clock button, where I can adjust the time, but not the date (which shows a date in 2016). The other buttons do nothing. I tried a soft reset (power + >>), and after a few seconds it turns off, then turns on, and the screen now shows what look a like a battery power symbol and a signal strength symbol, at upper right by the time display, both showing lowest level, and these go away after several seconds. I tried unplugging all the relevant fuses, but nothing helped. I even disassembled the center console enough to get at the display and sound unit to unplug them, still no help. So is it the APIM, or sound unit, or both?

Where some of the confusion here might come in is that Ford offered "Sync Destinations" until MFT went out of support. Basically if you had a free Sync Destinations account you could send turn by turn directions to any Ford newer than 2012 that didn't have Sync 3. You used the app or the web site to set the start/destination, put in the VIN and it would show turn by turn directions on the cluster message center (if the car didn't have NAV) or on the MFT screen is the car had NAV. 

I concure, I don't think Sync was avalable in 2013   Maybe a 3rd part would be able to assist ... 😎
