Tonite both reat wheel sensors stopped reading at the same time. Front works fine but back just show L and R and are blank behind them..any ideas??

 

Are there any codes? https://www.corvetteforum.com/guides...s/ipccodes.htm

Are the key fobs working okay?

Chances are all you need to do is run the tire sensor training procedure:

To train the sensors you need a strong (preferably u-shaped or circular) magnet. Some people have gotten them from Radio Shach, Home Depot, etc. An old speaker magnet will often work. These can be obtained from car stereo installation places from the factory speakers they replace.

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.

 

Thanks, I needed that too.

 

Thanks for the procedure..I tried it today. All worked until I got to the last wheel (L Rear) and the magnet would not make the horn beep. I tried it three tiems. I also let the air out of both rear tires and refilled them. Both rear sensors fail to read after all that.. I think it is strange that BOTH sensors would stop reading at the same time. Any other suggestions?

 

I had same problem. The battery went bad in my right rear sensor -- replaced the sensor & everything was ok and has worked since (about 4 months now).

 

I know this'll sound weird, but a GM rep told me about this procedure (honest... no kidding)

Using a rubber mallet, pound on the tire near the valve stem to free up a switch inside the sensor. Sometimes those magnetic switches get stuck and go haywire. Pounding - or kicking - may free it up and get it back to normal. I know it sounds odd, but I saw it work on someone else car.

If it corrects the problem but comes back later, replace the sensor.

Good luck.
