Adding trailer brake controller to 2024 F-150 Lariat

[jwclack52]

Thank you! I changed the one bit from 0 to 1 and that cleared the U2100, *but*... Before I had three entries in the IPC easy mode - after changing the as-built I only had one, trailer brake controller - no gain setting, etc. The truck responds to a squeeze of the controller and changes in gain setting (still says no trailer with my trailer emulator), but I'm a little worried about the absence of those two settings. Also, should I enable TBA? That wasn't there before.

Can anyone verify that this is what my IPC easy mode should look like after changing the TRM as-built to the correct config?

So it looks like I'll have to go the dealer ($$$) programming, too. :-(

Try the values below in the modules indicated. Ignore whatever you have where the x's and dashes are. After making the changes reset the APIM (FORScan wrench icon).
IPC 720-07-01 xxxx xExx xx--
BCM 726-69-02 xxxx x1xx xx--
TRM 791-01-02 xxxx x3--
APIM 7D0-09-03 xxxx xxx4 xx--
IPMA 706-18-01 xxxx xxxC xx--

Please report back after you install and try these changes and tag me in the post.

Livinitup, finally got around to this and everything appears to work. The gain adjust shows on the dash when hitting the + and - and the I get the trailer disconnected warning when activating the slider. I'll hook up to a trailer at work next week to double check. Thanks again for the coding, it was extremely easy to do!

I've added programming values for 2021-25 vehicles at the bottom of my Common Spreadsheet here

I was just hunting for parts for the second F150 we have and found there is now a part # RL3Z-19H332-AA Does anyone know if the part with the AA suffix rather than the single A is different? Perhaps it included the module and the switch?

When I called to order mine, I was told that a single A is for Max Tow package and AA is for standard tow package.
