Schrader 20096 TPMS Relearn Procedures

Your vehicle was equipped from the factory with a tire pressure monitoring system (TPMS) that turns on every time you start the engine.
There are two possible relearn procedures: 

When new sensors are installed, they must be registered by deflating the tires.
1.) Drive the vehicle for at least 2 minutes above 20mph. 
2.) Park near an air station and keep the ignition key in the OFF position.
3.) Turn the ignition to the ON position, but with the engine OFF.
4.) Turn the hazard flashers on and off three times within ten seconds, and the horn should sound. The TPMS light should be flashing letting you know that the vehicle is now in TPMS Relearn Mode.
5.) Starting with the drivers side front tire, activate the TPM sensor by deflating the tire for 10 seconds. Wait for the horn honk to confirm that the sensor has been registered to the vehicle. It may take up to 20 seconds for the horn to honk.
6.) Continue on to the passengers side front tire, and repeat the procedure in Step 5.
7.) Next, move to the passengers side rear tire, and repeat the procedure in Step 5.
8.) Finishing with the left rear tire, repeat the procedure in Step 5. Once the horn honks, turn the ignition switch to OFF to complete the TPMS relearn procedure.
9.) Make sure all tires, including the spare (if equipped), are inflated to the vehicles recommended inflation pressures.

When new sensors are installed, they must be registered using a TPMS triggering tool.

1.) Make sure all tires are inflated to the vehicles recommended inflation pressures (found in the owners manual on the door placard).
2.) Turn the ignition switch to OFF then press and release the brake pedal.
3.) Turn the ignition switch from OFF to RUN (engine OFF) 3 times, ending in the RUN position. Do this within 10 seconds.
4.) Press and release the brake pedal.
5.) Turn the ignition switch back to OFF.
6.) Turn the ignition switch from OFF to RUN (engine OFF) 3 times, ending in the RUN position. Do this within 10 seconds. 
7.) The horn should sound letting you know the vehicle has entered into TPMS relearn mode. 8.) Place the top of the TPMS triggering tool against the sidewall of the drivers side front tire in the location of the valve stem.
9a.) If using a VT10, hold down the left button of the VT10 triggering tool for 10-15 seconds. The vehicles horn will sound letting you know the sensor has been learned.
9b.) If using a VT15, press the left button, wait until the horn sounds, then press the right button to turn the tool off.
9c.) If using a FORDTRIGGER, press the center button. The vehicles horn will sound letting you know the sensor has been learned.
10.) Once the horn sounds, move on to the passenger side front tire and repeat the process. Each tire should only take 30 seconds or less.
11.) After the passenger side front tire has been learned, continue on to the passenger side rear tire and finishing with the drivers side rear tire.
12.) You may now turn the ignition to OFF. If the horn does not sound, the sensors were learned successfully. If the horn sounds twice, then the process must be repeated because there was a malfunction.
Each tire has its own pressure sensor. If the air pressure of a tire becomes severely low, the sensor in that tire immediately sends a signal that causes the tire pressure indicator in the instrument panel to come on.
