Tire Pressure Monitor System (TPMS)

TIRE PRESSURE MONITOR SYSTEM (TPMS) DIAGNOSTIC TROUBLE CODE (DTC) LIST

DTC	Description	Source	Perform Test
B106A	Pressure Sensor Range Bit Incorrect State	Smart Junction Box (SJB)	GO to PINPOINT TEST D .
B106B	Tire Pressure Sensor Low Battery (Could be set configuring new SJB)	SJB	GO to PINPOINT TEST E .
B1342	ECU is Defective	SJB	INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES .
B2477	Module Configuration Failure/Mismatch	SJB	DTC B2477 is only present when a new SJB is installed, the SJB is incorrectly flashed or the SJB is incorrectly configured. Successfully configuring the SJB is the only way to clear this DTC. Make sure the SJB is configured correctly. If the DTC B2477 is still present, REFER to MODULE COMMUNICATIONS NETWORK .
B2868	Left Front Tire Pressure Sensor Fault	SJB	DTC B2868 is only present when a new SJB is installed, the SJB is flashed or the SJB is reconfigured. TRAIN the tire pressure sensors. REFER to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING in this article.
B2869	Right Front Tire Pressure Sensor Fault	SJB	DTC B2869 is only present when a new SJB is installed, the SJB is flashed or the SJB is reconfigured. TRAIN the tire pressure sensors. REFER to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING in this article.
B2870	Right Rear Tire Pressure Sensor Fault	SJB	DTC B2870 is only present when a new SJB is installed, the SJB is flashed or the SJB is reconfigured. TRAIN the tire pressure sensors. REFER to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING in this article.
B2871	Left Rear Tire Pressure Sensor Fault	SJB	DTC B2871 is only present when a new SJB is installed, the SJB is flashed or the SJB is reconfigured. TRAIN the tire pressure sensors. REFER to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING in this article.
B2872	Tire Pressure Sensor Fault	SJB	NOTE: If the vehicle has been stationary for more than 30 minutes, the sensors will go into a "sleep mode" to conserve battery power. It will be necessary to wake them up so they will transmit the latest tire pressure information to the SJB. POSITION the tire pressure monitor activation tool against the LH tire sidewall, 180 degrees from the tire valve stem. PRESS the test button on the activation tool. The activation tool will provide feedback in the form of a flashing green light and a "beep" sound for each successful response from a tire pressure sensor. REPEAT this procedure for the remaining 3 sensors. GO to PINPOINT TEST C .
C2780	ECU in Manufacturing Mode	SJB	DTC C2780 is only present when a new SJB is installed, the SJB is flashed or the SJB is reconfigured. TRAIN the tire pressure sensors. REFER to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING in this article.
