Extended Mobility Tires

Making Your C5’s Wheels And Computer Speak The Same Language

Step By Step

It’s quite simple to set up the tire-pressure sensors to be recalibrated. Just make sure the car has been stationary for at least two minutes before attempting to reset the sensors. Turn the ignition on and press the RESET button to clear any messages. Press and release the OPTIONS button to scroll through the display options until the screen goes blank, then press and hold the RESET button for three seconds. Press the OPTIONS button again until the TIRE TRAINING message shows on the DIC.

Once the TIRE TRAINING message appears, press the RESET button until LEARN L FRONT TIRE shows in the DIC.

When you see the LEARN L FRONT TIRE message, go to the left front tire and prepare to recalibrate the sensor. GM calls for tool number J 41760 to be placed on the valve stem. You can do the same thing with a common magnet like what is typically used on a magnetic pick-up tool. Chris simply works the magnet around the valve stem until the horn sounds, which indicates that the sensor is calibrated. Then calibrate the next Tire Pressure Sensor as directed by the DIC. The order should be as follows: left front, right front, right rear, left rear.

Once the sequence is complete, the car will exit the programming mode and you can turn off the key. There are some other ways that the programming mode can be cancelled: Exit the programming through the DIC if you wish, or cancel the programming by simply turning off the key. Also, the car will exit the program mode if it remains in the mode for more than two minutes and no Tire Pressure Sensors are programmed.

Should a tire on your ’97-2001 Corvette ever pick up a nail on a dark, stormy night, you’ll greatly appreciate the use of Extended Mobility Tires. You’ll have much more flexibility in choosing where you’ll get that nail removed and the tire fixed.

With a typical tire, when the air is gone, the fun is over. To cue you that a tire has low air pressure, GM engineers put sensors on the wheels that constantly inform the computer of the air pressure inside the tire. If that pressure falls below a safe level, the computer will alert the driver to the situation through the Driver’s Information Console (DIC).

Great technology, if it works right. For any number of reasons, the sensor’s communication with the computer can become corrupted, and that can lead to the wrong tire being represented in the DIC, or to a complete loss of communication between the computer and the sensors. On the surface, this seems to be an involved, lengthy process, to be tinkered with only by people with thick-rimmed glasses and pocket protectors. This is not the case. We at Corvette Fever , under the direction of Chris Petris of the Corvette Clinic, will show you just how simple it really is to teach your wheels a thing or two.
