    Re: Tire Pressure Monitor-- Reset ?

    Found this in the manual -- hope it helps:

    TPMS Sensor Matching Process

    Each TPMS sensor has a unique identification code.
    Any time you replace one or more of the TPMS sensors
    or rotate your vehicle’s tires, the identification codes
    need to be matched to the new tire/wheel position.
    The sensors are matched to the tire/wheel positions in
    the following order: driver side front tire, passenger
    side front tire, passenger side rear tire, and driver side
    rear tire using a TPMS diagnostic tool. See your
    dealer/retailer for service.

    The TPMS sensors can also be matched to each
    tire/wheel position by increasing or decreasing the tire’s
    air pressure. If increasing the tire’s air pressure, do
    not exceed the maximum inflation pressure indicated on
    the tire’s sidewall. To decrease the tire’s air-pressure
    use the pointed end of the valve cap, a pencil-style
    air pressure gage, or a key.

    You 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 need to start over.

    The TPMS matching process is outlined below:

    1. Set the parking brake.

    2. Turn the ignition switch to ON/RUN with the
    engine off.

    3. Press the Remote Keyless Entry (RKE) transmitter’s
    lock and unlock buttons at the same time for
    approximately five seconds. The horn sounds
    twice to signal the receiver is in relearn mode
    and Tire Learning Active message displays on the
    DIC screen.

    4. Start with the driver side front tire.

    5. Remove the valve cap from the valve stem.
    Activate the TPMS sensor by increasing or
    decreasing the tire’s air pressure for 10 seconds,
    or until a horn chirp sounds. The horn chirp, which
    can take up to 30 seconds to sound, confirms
    that the TPMS sensor identification code has
    been matched to this tire position.

    6. Proceed to the passenger side front tire, and repeat
    the procedure in Step 5.

    7. Proceed to the passenger side rear tire, and repeat
    the procedure in Step 5.

    8. Proceed to the driver side rear tire, and repeat the
    procedure in Step 5.

    9. After hearing the confirming horn chirp, for the
    driver side rear tire, the horn sounds two more
    times to signal the tire learning mode is no longer
    active. Turn the ignition switch to LOCK/OFF.

    10. Set all four tires to the recommended air
    pressure level as indicated on the tire and
    loading information label.

    11. Put the valve caps back on the valve stems.

    Glad to be of help. I found it in the PDF version of the manual, which is searchable. I think there's a link to it someplace on this site.

    Has anyone tried doing this by lowering the pressure? I'm curious how easy it is to do.

    I rotated the tires and did this tpms thing in my garage. worked just like the book says.
    there is plenty of time, and it takes only a few pounds drop to ID each corner. I have a compressor so I could top them off after but there was enough air left to drive anywhere to put more in if you have to.

    Like Ronster and Mofex said, it's quick and easy!

    For unknown reasons, my TPMS stopped working altogether. So I reset and matched the sensors to the tires, per the owner's manual, and the system has since performed flawlessly. Also pleased with my Craftsman air compressor, and I wonder why I didn't buy one to keep in my garage years ago.

    Re: Tire Pressure Monitor-- Reset ?

    OK, one more question. If I have another set of tires/rims with TPMS sensors that are the same, can I swap out the tires and then just do the same procedure? Would it then register the new tires/rims?

    Yes, If the sensors are the correct part numbers you should be able to program the car to recognize those.

    If they are GM sensors compatible with the system the procedure should work...

    Re: Tire Pressure Monitor-- Reset ?

    For my car, that advice was close, but not close enough. If you only get one beep when you press the lock and unlock at the same time, and the above does not work, do this: Go find a big magnet and follow the instructions below:

    TPMS RELEARN & RESET PROCEDURES

    On the Corvette and Cadillac applications, the transponders in each wheel must be reset if the wheels are rotated to another position on the vehicle. This can be done by placing a J-41760 magnet over the valve stem or by using a Tech 2 or equivalent scan tool.

    Magnet method: With the key on, engine off, press both the lock and unlock buttons on the key fob. A horn chirp within 10 seconds indicates the TPMS receiver is in the programming mode. Place the magnet over the left front valve stem until the horn chirps. This forces the LF pressure sensor to transmit its code to the main module. Repeat the same procedure for the right front, right rear and left rear sensors in this order. Verify all four pressure readings are displayed on the driver information center.

    Any strong magnet will do. You can usually find one at any auto parts store or at an electronics shop.
