How to turn on 2001 deville TPMS system?

I have a 2001 cadillac deville dts with tire pressure monitors, but in the driver information panel, it doesn’t scroll through the different wheel pressures. When I read a tsb it says you can enable or disable through a scan tool or a tech 2. I used a snap on tool which shows what the monitors are reading, but it isn’t turning the system back on in the dash readout. If i scroll through the setting using the dash buttons, the enable/disable is missing as shown in the owner’s manual. Any help?

The tech 2 can acess the programming in the IPC and enable the tire monitiring.

I had to do that when replacing faulty IPC unit.

I don’t know if snap-on, matco, mac or otc scanner have that ability with out being enhanced. basic scanners are limited in abilities.
