My ‘25 Raptor started exhibiting this sound recently. Will have to bring to the dealer’s attention next time I’m in. Glad to at least know the source of it now.
Your coding looks spot on to me. I made the exact same changes on my '25 Raptor and got them to function. I would suggest triple checking your work and possibly resetting those modules to ASBUILT before trying again.
