Ford Non SYNC 3 Support

I just purchased a HJ5T-14G087-UF TCU of ebay that I want to install in the next few days. I want to get it done before my free 2-month Forscan access expires. I should be receiving the antenna any day. I understand there’s some programming that needs to be done to get this to work. I still have the factory Sync2 system and would like to get this done first before purchasing a Sync3 system. I’ve downloaded the asbuilt for my vehicle from Ford and have that (attached),

but I’m not quite sure what the steps are to do the conversion. I have a copy of the 21B09 from Ford that explains the steps for installing the new hardware, but once it’s all plugged in I haven’t yet found what I need to do to get everything configured. I did find a thread TCU HJ5T Asbuilt Discussion , but I’m still pretty new and not sure what I’m reading just yet. Sorry to be such a newb.

Is this a new or used unit?

You can’t use your AB as it’s for a 3G/G series unit.

Did you purchase the correct PFIFA antenna and cable since that needs to be replaced also?

Bill has a Ford dealer updated Energi, I believe you’ll find the correct ASBuilt on here.

To activate on a new unit you would follow apply Bill’s AB first to the TCU, then follow F150Chief’s doc and reapply Bill’s AB once you’ve got it activated.

I had Ford do the 4G update and the AB info has been a big help to many.

It is a used TCU.

Thank you! I will for sure refer to it. Actually, I did dig into it and was curious why your HPDM was disabled in the 754.02.01 x*xx-xx. I would have expected a value of E instead of A.

No idea, This is something Ford engineering setup. They did not share what it meant or why they set it that way.
