Pressure sensor operation when mounting Michelin Tires
Just had Michelin Pilot Sport A/S (not ZP) tires mounted on my 99 Hardtop. I was concerned about the operation of the tire pressure sensors. I insisted that the wheels be reinstalled in the same position from which they were removed. I even marked the wheel positions on the wheels. Apparently the installer followed my instructions, because the sensors worked perfectly when I picked up the car. It's too soon to comment on the Michelins, but they definately are smoother than the run-flats. I'll get back to the forum after I have some miles on them. Incidentally, one of the techs said that it was necessary for him to road test the car to check the operation of the sensors.
Yeah, Right.

Glad everything worked out. As far as the your last sentence, if I worked at a tire place etc. I would have given it the old test drive myself. :cheers:

Just to be sure, it's really easy to reset the sensors if you have a magnet:
To train the sensors you need a strong (preferably u-shaped or circular) magnet.
1. Turn key to ON (don't start the car)
2. Press the DIC RESET button to clear any warning messages, if they are present.
3. Press the OPTIONS button and cycle through the menu until the display goes blank.
4. Press and hold the RESET button until FOB training appears on the display.
5. Press the OPTIONS button once and the Tire Training message should appear.
6. Press the RESET button once, and the Learn Left Front Tire message appears.
7. Hold a magnet over the Valve Stem on left front wheel. You may have to move it around the valve stem to hit the right spot.
8. When the horn beeps (about 5 sec. later), programming is complete for THAT wheel.
9. Program the other 3 wheel sensors as directed by the DIC message display. The sequence is as follows: L Front, R Front, R Rear, L Rear.
You only have about 30 seconds, I believe, to train each tire. If the sensor isn't reset in that time, the training program shuts back down.
If your sensor isn't reading the pressure correctly, this procedure will not help. You can try letting out almost all of the air in the tire and refilling it. Sometimes that clears the sensors. If not, the sensor probably needs to be replaced.
