Pinpoint 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 or MONITOR FAULT and DTC B2872 or B287A is Present

Normal Operation
If there is a fault with 1, 2 or 3 of the tire pressure monitoring system (TPMS) sensors, DTC B2872 will be set, 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 smart junction box (SJB) does not get a response from all 4 of the TPMS sensors, DTC B287A will be set and the message center (if equipped) will display TIRE PRESSURE MONITOR FAULT.
^ B2872 Tire Pressure Sensor Fault - When 1, 2 or 3 of the tire pressure sensors are faulted or not responding, the SJB will set DTC B2872.
^ B287A Tire Pressure Monitor Fault - When all 4 of the tire pressure sensors are faulted, not responding or not heard by the SJB, 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
