DIY Factory Tow Package using OEM parts with Forscan As-built Data (without error codes)

[mikegt98]

I restored all settings back to factory specs and parking sensors still don’t work. No faults but getting error code U2101:00-08 for APIM and U2101:00-28 for PAM. Both say “Comtrol Module Configuration Incompatible”. Would the wrong TRM module cause this? I have confirmed all codes are correct for both modules per the motorcraft services as built files.

If you use forscan did you save your settings beforehand? Motorcraft website is not necessarily going to be accurate in all cases.
You say you don't have any faults but you're getting an error message, what is a fault?
Does that mean the MIL light's not on?
Have you tried to clear or reset the DTC?
Did you remove the bumper?
It is unlikely that it's the actual trm module.
You can prove this by unplugging it or removing the fuse for it if you didn't want to take the panel back off.

Yes I used the prior saved data and then downloaded the code to verify they matched. It all matched. So I pulled the TRM fuse and the APIM and PAM modes no longer have a fault. Also when I put it in gear the parking sensor fault doesn’t show up either. However the sensors are not picking up anything. The right front blipped one time and then back to nothing again. Anyone have any thoughts what else is needing to be reset. Probably pulling the TRM module back out so I can put the fuse back in and then pulling the battery negative off to see if I can reset everything

Well after I put the TRM fuse back in all the sensors have now started working. Go figure. If you know the right TRM module number for a 2026 model let me know and I’ll get that one ordered and replace it.

Can anyone confirm that the TRM module needed for a 2026 is m2dz19h332a
