Pinpoint Test D: DTCs B106A, B106B

Tire Pressure Monitoring System (TPMS)

Pinpoint Test D: DTCs B106A, 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 Tire Pressure Monitor (TPM) /Vehicle Security Module (VSM). The TPMS (Tire Pressure Monitoring System) warning indicator flashes for 70 seconds and then remains on continuously when the ignition switch is turned to the ON position.

- DTC B106A (TPMS Sensor Range Bit Incorrect State)- sets if an attempt has been made to train a non-compatible sensor.

- DTC B106B (Tire Pressure Sensor Low Battery)- sets if an attempt has been made to train a tire pressure sensor(s) with a low battery. This DTC can also set in the Tire Pressure Monitor (TPM) /Vehicle Security Module (VSM) during configuration.

This pinpoint test is intended to diagnose the following:

- Non-compatible sensor

- Tire pressure sensor battery

- Tire pressure sensor(s)

D1 DETERMINE WHICH SENSOR HAS A LOW BATTERY OR IS NON-COMPATIBLE

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

Did all of the tire pressure sensors transmit correctly and did the horn sound when each tire pressure sensor transmitted to the TPM (Tire Pressure Monitor) /VSM (Vehicle Security Module)?

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 Tire Pressure Monitoring System (TPMS) Sensor Service and Repair.
