Tire Pressure Sensor: Testing and Inspection
TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING
Note:
^
If the vehicle has been stationary for more than 30 minutes, the sensors will go into a "sleep mode" to conserve battery power. It will be necessary
to wake them up so they will transmit the latest tire pressure information to the smart junction box (SJB).
Note:
^
The tire pressure sensor training procedure must be done on a single vehicle, in an area without radio frequency noise and at least 1 m (3 ft) away
from other vehicles equipped with tire pressure monitoring system (TPMS).
Radio frequency noise is generated by electrical motors and appliance operation, cellular telephones, remote transmitters, power inverters and
portable entertainment equipment.
Note:
^
If a sensor does not respond to the activation tool, attempt to activate the same sensor with the activation tool. If the sensor still does not respond,
move the vehicle to rotate the wheels at least 1/4 of a turn and attempt to activate the same sensor again.
Note:
^
The SJB has a 2-minute time limit between sensor responses. If the SJB does not recognize any 1 of the 4 tire pressure sensors during this time
limit, the horn will sound twice and the message center (if equipped) will display TIRE NOT TRAINED REPEAT and the entire procedure must
be repeated.
Note:
^
For vehicles with different front and rear tire pressures, the tire pressure sensors must be trained following a tire rotation. Failure to train the
sensors will cause the TPMS indicator to illuminate. For vehicles with the same tire pressure for front and rear tires, tire rotation will not affect the
system.
1. Turn the ignition switch to the OFF position, then press and release the brake pedal.
2. Cycle the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN position.
3. Press and release the brake pedal.
4. Turn the ignition switch to the OFF position.
5. Turn the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN position.
^
The horn will sound once and the TPMS indicator will flash if the training mode has been entered successfully. If equipped, the message center
will display TRAIN LF TIRE.
Note:
^
It may take up to 6 seconds to activate a tire pressure sensor. During this time, the special tool must remain in place 180 degrees from the valve
stem.
Note:
^
If the SJB does not recognize any 1 of the 4 tire pressure sensors during the tire training procedure, the horn will sound twice and the message
center (if equipped) will display TIRE NOT TRAINED REPEAT and the procedure must be repeated.
6. Place the activation tool on the LF tire sidewall opposite (180 degrees) from the valve stem. Press and release the test button on the special tool.
The horn will sound briefly to indicate that the tire pressure sensor has been recognized by the SJB.
