Park assist control module location 2009 Ram 1500?

[09TRX]

I’m getting a message to service the park assist system in my truck. It basically doesn’t work. When I turn on the ignition the yellow light on the dash disable button is lit as are all the indicator lights above the rear window. Pushing the button doesn’t do any good.
I’ve checked the sensors with a VOM and they all read the same, I can’t imagine that all four would fail at the same time. Likewise the connections are clean and dry.
I’ve disconnected the battery hoping to clear any faults but that hasn’t work either.
Next step is to check the control module but I haven’t found it’s location.

Hoping someone replies…same problem here. I replaced my sensors, then my connecting harness today, still nothing. Mine is a 2012 and I think my control module is under the headrest.
