14 JK Sport. Successfully used the ProCal to adjust for new tire diameter no problem. My issue is occurring when trying to either shut off or lower tpms threshold. When I adjust the dip switches according to the pdf instruction settings Im not getting the 2 horn beeps to confirm that the new setting takes effect. It's basically unresponsive. I can't make any change to the factory tpms threshold of 35 psi. Am I doing something incorrectly? Again- I'm setting the switches correctly but it's as if nothing is occurring. I'm getting zero response. Any help would be greatly appreciated.
