Test F: TPMS Indicator FLASHES for 70 Seconds and Then Remains ON Solid When the Ignition Key is Turned to the ON Position, the Message Center (if equipped) Displays TIRE PRESSURE SENSOR FAULT and DTC B2872 or B287A is Present

Normal Operation
If there is a fault in the tire pressure monitoring system (TPMS), such as a damaged or missing sensor(s), damaged module or a communication issue within the vehicle, DTCs are set in the smart junction box (SJB), the TPMS warning indicator will flash for 70 seconds and then remain ON solid when the ignition switch is turned to the ON position and the message center (if equipped) will display TIRE PRESSURE SENSOR FAULT.
If the SJB does not get a response from any of the TPMS sensors, DTC B287A may be set and the message center (if equipped) will display TIRE PRESSURE MONITOR FAULT.
^ B2872 Tire Pressure Sensor Fault - When any of the tire pressure sensors are faulted or not responding, the SJB will set DTC B2872.
^ B287A Tire Pressure System Fault - When all of the tire pressure sensors are faulted or not responding, the SJB will set DTC B287A.

This pinpoint test is intended to diagnose the following:
^ TPMS sensor(s) missing
^ TPMS sensor(s) not trained to the vehicle
^ TPMS sensor(s) swapped due to wheel swap
^ TPMS sensor(s) damaged
^ Vehicle communication issue
^ SJB
