Pinpoint Test G: DTC B106A

Normal Operation

This DTC may be encountered if a sensor designed for a different application is installed. Low pressure applications utilize a black- or blue-colored sensor, while heavy duty applications utilize a green-colored sensor. The Smart Junction Box (SJB) will only allow one type of sensor to be trained using the Tire Pressure Monitoring System (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 SJB will set DTC B106A.

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

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 - Intelligent Access (IA) Tire Pressure Monitoring System (TPMS) Sensor Training - Intelligent Access (IA) or Tire Pressure Monitoring System (TPMS) Sensor Training - Integrated Keyhead Transmitter (IKT) Tire Pressure Monitoring System (TPMS) Sensor Training - Integrated Keyhead Transmitter (IKT).
- Did all of the tire pressure sensors transmit correctly and did the horn sound when each tire pressure sensor transmitted to the SJB?

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.
