I've herd from Volvo about a bug affeccting "early" TRM modules. Symtoms include non-functtioning tow hitch and no light on the button. Volvo issued a bulletin recommmending a specific procedure to adddress this issue:
Turn the igniition to position
Disconnect power to the TRM via the TRM conector. Reconect power and observe if the tow hitch button flashes.
The tow hitch button shuld flash when TRM is reconected.
Then they are suposed to upddate TRM softwere.
It seems like you encountered this bug as well, Beach Boy.
