    A bit of a head scratcher re tire rotation...

    The question came to mind about tire rotation and the pressure monitoring system. I'm not familiar with some of the criteria of the monitor and as such I ask, will the monitor still show accurately which tire is being read on its display after rotation? The system should still read the pressures but will it "know" what wheel it is actually reading? Would the data be specific to the transponder at the wheel or the receiver in the car?

    Or, am I just worrying about a "what if" that isn't an issue?

    Yes. The 'gotcha' is the tires/wheels will be in different locations after the rotation therefore the display for the LF tire/wheel will indicate the pressure in the tire that "used to be" in the LF position.

    Would the data be specific to the transponder at the wheel or the receiver in the car?
    The pressure data is specific to the sensor/transmitter in each wheel.

    Following a rotation it is necessary to have the receiver relearn the vehicle position of the four transmitters. Easy enough on your car.

    Use a large magnet. If this procedure fails, try a magnet with greater flux density.

    1) Ignition ON.

    2) Press LOCK + UN-LOCK key fob buttons simultaneously until the horn chirps.

    3) Starting with LF wheel, hold the magnet in contact with the valve stem
    until the horn chirps. Then RF, then RR, then LR. After LR, the horn
    will chirp twice to indicate the relearn was successful.

    There is a timer running that allows 1 minute between wheels and
    5 minutes total elapsed time.

    AND, if it doesn't work, you may have to wait for warmer weather. Mine don't seem to take the recalibration in cold weather.

    Jim, thanks very much for bringing me up to speed on how the system functions and for the great walk through of the recalibration process...it did have me wondering. I just might print those instructions in a business card size, laminate it and it can live in the glovebox

    Thanks for that Ranger..."If at first you don't succeed, try again in the spring"
