What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I’ve programmed new remotes with remote start capability for each of the twins. I’ve done the lock then press and hold on the start buttons. Both twins are responding by flashing the parking lights. I’m guessing there is some additional toggle that has to be flipped to get the functionality turned on. Both have the AP8 remote start capable option.
