I have replaced the BCM in my '09 Acadia with a new unit programmed to the VIN. Now the manual hatch does not unlock with the FOB or at the door. Does something need to be switched on or calibrated with the BCM once installed similar to the airbag and ABS witch? Anyone know? If the relay in behind the glove box is jumped, it does unlock. Any help is appreciated.

Dumb question, but did you get the correct BCM? I believe there are two different units for an '09.

It was the 22860591 box which I believe is the only service replacement. I could be wrong though.

The BCM part number appears to be correct. Maybe the relay you jumped has gone bad.

I thought the same, changed the relay and made no difference. I’m puzzled. I do not have access to a good reader, is there a manual setting within the BCM that needs to be configured if it is manual or motorized hatch?

That should have been in the VIN coding when you had the BCM programmed.
