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 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 SJB?

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 - Valve Stem Mounted Tire Pressure Monitoring System (TPMS) Sensor - Valve Stem Mounted or Tire Pressure Monitoring System (TPMS) Sensor - Strap and Cradle Mounted Tire Pressure Monitoring System (TPMS) Sensor - Strap and Cradle Mounted.
