The saga ends. Discount Tire installed new FoMoCo OEM sensors and they were able to get them to activate by using the combo of start button plus brake pumps to get it into learning mode. Then they were able to use their tool to trigger the truck to recognize each sensor starting at the drivers front, then passenger front, then passenger rear and finally driver rear with a short honk at each stop indicating success. Up to this point, I don't think that they actually completed the process to get it into learning mode. They had tried initiating it via ODBII the previous visit which was not obviously not successful. For reference, here is a pic of the OEM TPMS sensor package with P/N.
