TCM MODULE ?

I have a 2021 F350 Platinum and am trying to find the TCM module. Anyone know why it doesn't show in the configuration screen? I want to do the relearn procedure for changing tire size in Forscan.

Isn't tire size changed in the BCM?

Are you trying to reset the adaptive learning tables in the TCM?

You are missing modules, are you using a adapter with a switch? Are you allowing forscan to load a previous saved profile?

When you first try to connect, forscan will ask if you want to load previous saved vehicle. Select no, it will then ask after it looks if the device has a switch. Select yes to that question and it should find all the modules.

When I select "no" to load previous data,I get message saying unable to connect. Ignition is on. I'm stumped for what to do.

I GOT IT!! Not really sure how. I deleted profile of the truck then tried to reconnect with the reader that has m/h switch. Would not connect. Then tried my Bluetooth reader and it connected and showed the TCM. Did relearn on TCM and the wrench light is gone!

The switch is in the wrong position, flip the switch.

I'm using the OBDLink MX Wifi adapter (they no longer make this version) and I don't see any TCM module. There is no switch on this adapter but it's supposed to support TCM. I have a 2023 F150 Powerboost and have successfully reprogrammed items in other modules. Could it be that the 2023 F150 XLT Powerboost doesn't have a separate TCM module? Perhaps everything is in the PCM module now?
