Check that the Pressure Warning Limit under Dash Settings, then Tires and Wheels is not set to 0. A value of 0 disables TPMS completely, and it is the most common reason a customer reports no TPMS data.

Check in order:

1. Pressure Warning Limit. Any value above 0 enables TPMS. 0 disables it.
2. Sensor pairing. Confirm the tire sensors are paired to the system.
3. Sensor batteries. TPMS sensors have a finite battery life and fail quietly.
4. Debug Data View. Confirm tire pressure channels are arriving.
5. After a tire change. Sensors moved between wheels need to be re-paired to the correct positions.
