Pinpoint Test G: 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 or TIRE PRESSURE MONITOR FAULT and DTC B2872 or B287A is Present

NOTE: A full-sized, matching spare wheel and tire, that is identical to the road wheel and tire, is available as an optional accessory. This spare wheel and tire is equipped with a tire pressure sensor but the sensor is not initially programmed to the driver door module (DDM).

If this spare wheel and tire is in use on the vehicle, the sensor must be trained to the DDM and the remaining 3 sensors must be retrained to the DDM as well. If all 4 sensors are not trained to the DDM, the tire pressure monitor system (TPMS) warning indicator will illuminate.

Make sure that all the wheels and tires installed on the vehicle are inflated to the correct pressure and trained to the DDM before attempting to diagnose a TPMS concern. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training. Tire Pressure Monitoring System (TPMS) Sensor Training

Normal Operation
If there is a fault in the TPMS, such as a damaged or missing sensor(s), damaged module or a communication issue within the vehicle, DTCs are set in the driver door module (DDM), 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. When any of the tire pressure sensors are faulted or not responding, the DDM will set DTC B2872 and the message center (if equipped) will display TIRE PRESSURE SENSOR FAULT. When the DDM does not get a response from any of the tire pressure sensors, DTC B287A will be set and the message center (if equipped) will display TIRE PRESSURE MONITOR FAULT.
^ DTC B2872 Tire Pressure Sensor Fault - When 1, 2 or 3 of the tire pressure sensors are faulted or not responding, the smart junction box (SJB) will set DTC B2872.
^ DTC 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
^ DDM antenna
^ DDM
