    2007 and up Tire Pressure Sensor Relearn

    Resetting the TPMS Identification Codes
    Each TPMS sensor has a unique identification
    code. Any time you rotate your vehicleís tires
    or replace one or more of the TPMS sensors,
    the identification codes will need to be matched
    to the new tire/wheel position. The sensors
    are matched to the tire/wheel positions in the
    following order: driverís side front tire, passengers
    side front tire, passengers side rear tire, and
    driverís side rear tire using a TPMS diagnostic
    tool. See your GM dealer for service.
    The TPMS sensors may also be matched to each
    tire/wheel position by increasing or decreasing
    the tireís air pressure. If increasing the tireís
    air pressure, do not exceed the maximum inflation
    pressure indicated on the tireís sidewall.
    You will have two minutes to match the first tire/
    wheel position, and five minutes overall to match
    all four tire/wheel positions. If it takes longer
    than two minutes, to match the first tire and wheel,
    or more than five minutes to match all four tire
    and wheel positions the matching process stops
    and you will need to start over.
    The TPMS sensor matching process is
    outlined below:
    1. Set the parking brake.
    2. Turn the ignition switch to RUN with the
    engine off.
    3. Using the DIC, press the vehicle information
    button until the PRESS
    V TO RELEARN
    TIRE POSITIONS message displays.
    4. Press the set/reset button. The horn will
    sound twice to indicate the TPMS receiver
    is ready, and the TIRE LEARNING ACTIVE
    message will display.
    5. Start with the driverís side front tire.
    6. Remove the valve cap from the valve
    cap stem. Activate the TPMS sensor by
    increasing or decreasing the tireís air
    pressure for five seconds, or until a horn
    chirp sounds. The horn chirp, which make
    take up to 30 seconds to sound, confirms
    that the sensor identification code has been
    matched to this tire and wheel position.
    To decrease air-pressure out of a tire you
    can use the pointed end of the valve cap,
    a pencil-style air pressure gage, or a key.
    7. Proceed to the passengerís side front tire,
    and repeat the procedure in Step 6.
    8. Proceed to the passengerís side rear tire,
    and repeat the procedure in Step 6.
    9. Proceed to the driverís side rear tire, and
    repeat the procedure in Step 6.
    10. After hearing the confirming horn chirp for
    the driverís side rear tire, the horn chirp
    will sound two more times to signal the
    tire learning mode is no longer active.
    Turn the ignition switch to LOCK.
    11. Set all four tires to the recommended
    air pressure level as indicated on the Tire
    and Loading Information label.
    12. Put the valve caps back on the valve stems
    The spare tire does not have a TPMS sensor.
    If you replace one of the road tires with the spare,
    the SERVICE TIRE MONITOR message will be
    displayed on the DIC screen. This message should
    go off once you re-install the road tire containing
    the TPMS sensor.

    Thumbs up Re: 2007 and up Tire Pressure Sensor Relearn

    Thanks for the info.
    That method sure beats the method I had to use on the C5 Corvette I use to have where I had to wave a magnet over the sensor to trigger the reset function. What a PITA that was.

    With the right magnet the C5's were not too bad, I had 5 of them.

    Re: 2007 and up Tire Pressure Sensor Relearn

    Just a note. I have an 08 EXT and this did not work.

    Instead of using the computer and finding a menu to choose to relearn the sensors I had to do the following

    1. Set parking break
    2. Turn vehicle to run position, but don't turn car on.
    3. Press and hold both LOCK and UNLOCK buttons on car remote at the same time... continue holding for 5 seconds or so until horn honks twice.

    4. then start at driver side front tire and let air in or out, and follow rest of the steps above.

    Hope this helps someone!

    Re: 2007 and up Tire Pressure Sensor Relearn

    This process is not as easy as it sounds. It is a MAJOR pain in the ass. I had to repeat the procedure 4 times to get all 4 tires to reset. It sometimes takes over a minute before the horn chirps to recognize that the tire's air pressure has changed. If that is the case for all 4 tires then you run out of time and have to start over. You can also run out of air pressure if you are releasing air to reset the sensors.
    Am I doing something wrong?
    Instead of continuing to release or add air to the tire until a tire chirp, should I instead add or release air for 5 or 6 seconds and then wait for the sensor to recognize the change?
    I need to do this again because the right rear initially did reset and was recognized but later was not recognized by the sensors.
    Help!!!

    I feel your pain!

    As a comparison, on BMW, with I-Drive, it takes about 30 seconds......total!

    I just can't believe the above procedure is for real. Has anyone actually had the dealer/service dept. do it and observed the process they use?

    Re: 2007 and up Tire Pressure Sensor Relearn

    Hey guys... I did this on my new 08 and it was SUPER easy.


    I simply made sure I had at least 40 psi in the tires before starting...

    after the horn honked to show me that it was ready to learn, I went to the driver side front tire... used a small screw driver, let out a little bit of air.... HONK, then went to passenger front, let out a little.. HONK, then passeger rear, then driver rear.

    I would guess it took maybe 5 - 10 seconds of letting out air with the screw driver to get the honk

    after I was done learning all 4, I had a friend sit in the driver seat and watch the pressures.... I then went around to each tire and aired them up until my display inside showed 40.

    if the entire process took 5 minutes I would be suprised.

    Hopefully this might help.

    This process does work on "some" 07's and 08's, it works on one of my two 07's, as posted above if you overfill the tires to start with it goes easier. I wanted to do it faster so I purchased a tool and it works great. You can find them on E-Bay from time to time dirt cheap

    Re: 2007 and up Tire Pressure Sensor Relearn

    Carl i just did the original method as in post #1 last night and it worked like a charm. First try and each side honked after about 5 -10 seconds depending. Thanks!

    You are welcome Marco. That method works on my older 07' but not the newer one. That's why I purchased the Bartec unit

    Re: 2007 and up Tire Pressure Sensor Relearn

    2009 Escalades no longer have this procedure. You have to own the Tech 2 or the specific J-Tool to re-program the sensors which means you have to visit the dealer. I found this out yesterday!

    Do they still list the reprogram of tire sensors on the DIC?

    NOPE! You can do the key FOB re-learn, but not the tire pressure sensor re-learn procedure. Very weird.

    Shawn, well that really sucks, so every time you rotate your tires you will now have to go to the dealership, my Bartec tool will not work if you can not call up the pressure sensor relearn, I would rather have the TPMS than the FOB, what the hell were they thinking, I change tires and wheels like people change their shoes. I can get the latest Bartec 400 for 2k, I guess there will be no 09' for me, just called my salesman and told him to cancel the order or buy me the tool.
