2018 V90CC - Use OrBit to Add/Program a Hitch CTRL Module?

[richardGG24]

I'm 99% sure Orbit config change alone is not enough, you also need to make sure TRM has the correct software loaded.

Correct. When you have a new TRM module, you need to load software first using Vida. A used TRM may work, but it's a hit and miss.

I'm sure someone fitted a hitch to an xc60 or XC90 with a used module and, while it didn't seem to work right after install, it sorted itself out and started working fine after being left overnight. There's a thread on here with the details.

IIRC I experienced the same thing when I fitted the factory hitch on my V60CC with VIDA, it didn't work immediately after the installation, had to let it sit for a while. Used TRM should work as long as the donor part is loaded with the correct software for your vehicle, that basically skips the VIDA coding part. But you might run into issues say if you try to fit a used TRM pulled out of a XC90 into a V90CC. I'm sure there is more to it, things like destination market, drivetrain type, model year and such probably matters for the software.
