I have not seen an issue with the TPMS as I ran accross today. I hought new tires, NITTO NT555s, for my 2004 C5 coupe. Noticed that discount tire swapped the sides my wheels were on originally, wheel rash, was my clue. After the first few miles the Service tire monitoring system message sdtarted to flash. Took it back to discount and they attempted to reprogram sensors. That lasted a few days and the message came back. Had some spare time on my hands today, took car to dealer.

Dealer pulled a servicce bulletin or some sort of dealer info with "document ID: 1899192" that basically stated to verify all tires are Goodyear Eagle F1 "EMT" tires; verify that the wheels are the original/same year vintage. Dealer removed one tire from vehicle, took tire off rim and stated the sensor was found. Could not find sensor with tire on wheel therefore not having OEM tires causes my TPMS to be inop. Any ideas?

 

There is a lot of info in the search for this stuff. Why not try to program youself? You just need a strong magnet and do a search. Not hard. Good luck. Probably somebody will post the exact process for you, I just dont have it to give you.

 

It almost sounds like your batteries are going dead, the type of tire shouldnt affect the operation of the tpms.

 

Actually there was a service bulletin on the type of tires causing potential problems with the TPMS. Here is the text of the bulletin:

1997 - 2001: Service Bulletin: Info - Wheel Pressure Sensors Unable to be Reprogrammed after Tire Replacement

Source: Chevrolet Dealer Service Bulletin
Number: 00-03-10-005
Subject: Info - Wheel Pressure Sensors Unable to be Reprogrammed after Tire Replacement
Model Year: 1997-2001

Some dealers may find it difficult to reprogram the wheel mounted air pressure sensors on vehicles which have replacement tires installed. If this is the case, verify the brand and model of the tires. One tire that is known to cause this condition is the Goodyear® Eagle™ F-1. The Goodyear® Eagle™ F-1 uses a unique "all-steel" case construction. The sidewall reinforcement, as well as the tread belts, are made from a woven steel strand material. The presence of this material may cause degradation of the signals generated by the wheel mounted sensors. Original Equipment Manufacturer (OEM) replacement tires must have Goodyear® Eagle™ F-1 GS EMT molded into the sidewall of the tire. If the tire does not have the GS designation, it is an all steel construction Goodyear® Eagle™ F-1 tire.

This type of interference may not be limited to the Goodyear® Eagle™ F-1 tire. As other manufacturers produce replacements for the Corvette, the individual peculiarities of those tires cannot be predicted. Using OEM replacement tires as identified above is the customer's best assurance of trouble free performance.

What to Advise the Customer
If an inspection of the wheel mounted sensor reveals no visible damage caused by improper installation of the tires, you should recommend that the customer install OEM tires to correct this condition. Further point out to the customer that the current aftermarket tires do not afford the run-flat feature of the original equipment tires. As the Corvette is not fitted with a spare tire, this could be a serious inconvenience to the customer.

I think I would try and program it myself if I were you and see if you can't get it to take. One thing to try if the normal method doesn't work is to place the magnet on the barrel of the wheel right over where the TPS is mounted and see if it will sync with the car then.

Here's the procedure to programming the TPS:

To train the sensors, you need a strong (preferably u-shaped or circular) magnet. Some people have gotten them from Radio Shack, 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 the 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 the left front wheel. You may have to move it around the valve step to hit the right spot.
8. When the horn beeps (about five seconds later), programming is complete for that wheel.
9. Program the other three wheel sensors as directed by the DIC message display. The sequence is as follows: Left front, right front, right rear, left 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.

 

i have ordered new sensors and when gmpartshouse gets them to me, i'm hoping that will solve the problem. I have bought nearly every magnet in Las Vegas so this is next to my last hope.

 

Program the new sensors before you mount them on the wheel, mark them for correct position on the car and make sure they mount the sensors in the correct wheel you marked on the new sensor. It won't take as strong a magnet if you are holding the sensor in your hand when programming.

 

good advice.

Are you getting any codes?

Nitto 555s are runflats, correct?

As the link Jack provided suggests, other runflat tires might have more metallic material in the sidewall than a stock runflat or a non-runflat. As the TPM works at radio frequencies it may affect the ability of the receiver to see the programming signal or transmit to the RFA. That said, I've never heard of tires which prevented the signal being received and plenty of members here have used Nittos.

When I fitted my new Toyo Proxes (non RF) on Cray rims I found that the sensors were much harder to program. The old speaker magnet I'd used on the stock wheels wouldn't work. I bought a much stronger magnet and tried again. Even holding that close to the sensor didn't work at first and it was only when it accidentally clamped to the rotor that I got the beep.

The secret normally is a bigger magnet. This is the one I bought for a few £. If you found a similar one in Vegas, try letting it clamp itself to the rotor.



As others have said, it might be that the sensors are old and theres enough power to prevent a code setting or showing a XXX on the DIC but the RF signal is too weak to work correctly. If you bought new ones already, try 65GGvert's suggestion and program them off the car which is certain to work.

 

If you are getting the service tire message, see what sensor is malfunctioning! My new sensors had problems when I mounted new tires. I had a difficult time programing the RR. In addition, my RF would loose contact at high speeds. After driving for a while all appears to be fine.

 

The function of the TPMS has nothing to do with the brand of tires that you're running.

 

Nitto 555 are not run flats. no codes just the message flashing accross the DIC. new sensors installed and programed by Chevy dealer ($120) solved the problem

 

There are thousands of people on this forum as well as hundreds of thousands of C5s world wide that have non oem tires with no TPMS issues. Discount wanted 10 bucks per tire to program. I did it at home with a speaker magnet.

 

Glad you got your prob fixed, But 120 bucks for a 5 min job is way too much, I bought 4 new sensors at Kragen for 38 bucks each and had them installed. I programed them before the install and marked them rr,lr, rf,lf and worked like a champ.

You'd have to use a Nascar pit crew to install 4 sensors in 5 min. If that didn't include the price of any sensors, it might be high, but breaking down the tires to replace is time consuming and risky, so doesn't seem outrageous to me.

 

I just had new tires (Hankook) and new sensors (TireRack) installed on my 98 C5. The magnet I used with the old sensors didn't work when I tried to program the new sensors. So I went down to Lowes and picked up a stronger magnet and tried it again. Programed the fist try and took less than five minutes. Magnet cost about two bucks .
