Pinpoint Tests

Pinpoint Test G: DTC B106A

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 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.

This DTC may be encountered if a high-pressure sensor (designed for trucks with much higher tire pressures and molded in green plastic) was installed. The DDM will only allow a low-pressure sensor to be trained using the TPMS sensor training procedure. Make sure the correct sensors are used to avoid compatibility issues.

- DTC B106A (Pressure Sensor Range Bit Incorrect State) - When an attempt has been made to train a non-compatible sensor, the DDM will set DTC B106A.

This pinpoint test is intended to diagnose the following:
- Tire pressure sensor(s)
- Incorrect tire pressure sensor(s) installed
- DDM

G1 DETERMINE IF THE VEHICLE IS EQUIPPED WITH AN INCORRECT SENSOR


- 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 DDM?

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

No
Before installing a new sensor(s): If a sensor(s) does not respond to the Tire Pressure Monitor Activation Tool, ATTEMPT to activate the same sensor(s) with the Tire Pressure Monitor Activation Tool. If the sensor(s) still does not respond, MOVE the vehicle to rotate the wheels at least one-fourth turn and ATTEMPT to activate the same sensor(s) again.

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 Tire Pressure Monitoring System (TPMS) Sensor.
