Pinpoint Test H: DTC B106B

Tire Pressure Monitoring System (TPMS)

Pinpoint Test H: DTC B106B

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 (Tire Pressure Monitoring System) warning indicator flashes for 70 seconds and then remain ON continuously when the ignition switch is turned to the ON position and the message center displays TIRE PRESSURE SENSOR FAULT.

The tire pressure sensor is battery powered.

This DTC may be set when attempting to train a tire pressure sensor(s) with a low battery.

This pinpoint test is intended to diagnose the following:

- Tire pressure sensor battery

- Tire pressure sensor(s)

PINPOINT TEST H : DTC B106B

NOTE: DTC B106B can be set during SJB (Smart Junction Box) configuration.

H1 DETERMINE WHICH SENSOR HAS A LOW BATTERY

- Train all 4 tire pressure sensors. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training Sensor Training.

Did all of the tire pressure sensors transmit correctly and did the horn sound when each tire pressure sensor transmitted to the SJB (Smart Junction Box)?

Yes
CLEAR the DTCs. REPEAT the self-test. VERIFY system operation.

No

Before installing a new sensor(s): If a sensor does not respond to the Tire Pressure Monitor Activation Tool, MOVE the vehicle to rotate the wheels at least one-fourth of a turn and ATTEMPT to activate the same sensor again.
If the sensor still does not respond, ATTEMPT to activate the same sensor again using the customer activation tool (if available). If the sensor still fails to train, ATTEMPT to train the sensor with the vehicle doors open.

If the sensor(s) fails to train a second time, INSTALL a new tire pressure sensor(s). REFER to Wheel and Tire - Valve Stem Mounted Tire Pressure Monitoring System (TPMS) Sensor Wheel and Tire - Valve Stem Mounted Tire Pressure Monitoring System (TPMS) Sensor.
