Found this little relearn procedure on ebay:

RELEARN PROCEDURE FOR
Chevrolet Corvette-C6 05 -09

1. Turn ignition to RUN position
2. Press and hold unlock and lock buttons on the keyless entry transmitter until horn sounds.
3. Starting with LF tire increase/decrease the pressure until horn sounds.
4. After horn sounds proceed as in step 3 for the next 3 sensors in the following order: RF, RR, LR, After completing LR tire horn will sound twice.
5. Turn ignition to OFF position to exit vehicle learn mode. Adjust all tires to pressure listed on tire placard.

Did you try it on yours?

One question, where is the 'RUN' position. There is a start/crank and accessories, but no RUN

Seadawg

EDITED - updated per better info as posted below - thanks Fort MorganAl:

"BTW, "Run" is holding the bottom of the start button (not the top) until the green light comes on again and the dash lights up."

And thanks BEZ06 for all of your detailed clarification below, this procedure does cover some C6's as you describe below.

I would imagine for an automatic you push the start button while in gear?

Gman in NC

My Equinox sets the tpms like that but not sure about the Vette. Have to give it a try.

You might want to do a search and see that this procedure isn't for a C6 Corvette. You have to have the TPMS tool to match C6 TPMS sensors to the car.

BTW, "Run" is holding the bottom of the start button (not the top) until the green light comes on again and the dash lights up.


Here is the correct TPMS relearn procedure - http://www.tirerack.com/images/tpms/...structions.pdf

If someone try this with an auto please let me know. Planning on buying 4 new sensors and tires. Thanks

mcandrew67

early 05 sensors were activated by a magnet, I bought a tool to do mine fairly cheap.
Bob(BEZ06) is the TPMS guru and can tell you the ins and outs of all the different TPMS

BEZ06

The change in tire pressure method WILL ONLY WORK ON A 2010 or 2011 BUILT THROUGH DECEMBER 2010!!!

The 2005-2009 model years have a TPMS that uses a tire pressure sensor that requires the signal transmitted by a TPMS tool in order to trigger it during the relearn procedure which programs the sensor ID#'s into the TPMS computer memory in the car.

With the 2010 model year, they changed the TPMS to one that uses a sensor that can be triggered by changing air pressure in the tire.

They continued to install that sensor into 2011 C6's built through December 2010.

Starting in January 2011 they began building the C6 with a different sensor (same TPMS, just a different sensor). The new sensor WILL NOT trigger by changing air pressure - it requires the signal from a TPMS tool.

So.....if you have a 2010 or early 2011, it should have the green sensor with GM Part# 15268606 which can triggered by changing air pressure, or it will also trigger with a TPMS tool.

If you have a C6 built after January 2011, it came with sensors that must be triggered by a TPMS tool.

If you do have a late 2011 or newer C6, you can use the green sensors. There may still be some available through GM parts distributors, and new and used ones are available on eBay and other sources. That green sensor was used in numerous other GM vehicles for a couple years before they started installing them in the 2010 C6.

When doing the relearn procedure, the first thing you do is to put the ignition in the ACCESSORY mode by pushing the bottom of the ignition switch to get the yellow light illuminated by ACC.

Watch the video below to see the entire relearn procedure using a TIPS TPMS tool. If you have a 2010 or early 2011 (or if you have a late 2011-2013 and switched over to the green sensors, or put green sensors into a second set of track wheels) then where I'm using the TPMS tool to excite/trigger the sensor you would instead just change air pressure to trigger the green sensor.

Hi David

I have a set of 4 of those early sensors that will trigger with a magnet.

If you're interested $120 shipped. They will work in any 2005-2009 C6.




Or, if anybody with a 2010 or newer is interested in a set of the green sensors that will trigger by changing air pressure, I have set available for $120 shipped.




Also, I have a used TIPS tool like in that video for $135 shipped.

Foot off brake, press & hold start button. ACCS comes on first, then a few seconds later it will be in RUN. Also a good way to get battery voltage

BEZ06

I checked your profile and it shows that you have a 2005 - so fagidaboudit!!!! If you get 4 new sensors for your 2005 they must be triggered by a TPMS tool.

If you have a VERY early 2005 (built in about Aug 2004 or prior) you may have the magnetically triggered sensors that mcandrew67 mentioned, and I have a picture of in my earlier post.

Those sensors were used in the 2004 Cadillac XLR and very early 2005 C6's, and they are not manufactured anymore.

You say you're getting new sensors for your 2005, so you will need to get the gray sensors that are GM part# 25758220:




There are some aftermarket ones from Oro-Tek, Orange Electronics, and Dorman (the Dorman ones have gotten a few bad reviews here on the forum). Just make sure that if you get aftermarket that they are compatible with the 25758220 factory sensor. The factory sensors are made by Schrader, and there are some Schrader ones available from outside the GM parts distribution sources, but they are usually red in color.

Any new sensors you get for any 2005-2009 C6 will require a TPMS tool to trigger them during the relearn procedure to program them into your TPMS memory.

No automatic programming takes place at all, and if you just replace one sensor, all 4 will need to be reprogrammed into the TPMS.

Just to highlight the mode the ignition must be in to put the car into the "learn mode" to prepare it for programming the sensors into the TPMS - the ignition must be put into the ACC mode!!!

The parking brake does not have to be on in the C6.

Also, after you put the car into the learn mode, you must trigger the first sensor within one minute or the learn mode will time out.

Very interesting, thanks for all of the clarification BEZ06!

I need to check to see when my 2011 was built now....... It was delivered in January of 2011 to the dealership, but I need to read what the official build date is.

Would it hurt to try this procedure on my "questionable 2011", even if it did not work?

I actually need to do something, because I discovered recently that my front tire sensors are on the "wrong side", they were careless when changing my tires........

vetteguy4

Put the ignition in "ACC" mode and press unlock and lock on the fob at the same time. Horn will sound indicating computor is ready. Did this recently on my 2008 Auto.

Fun...I was waiting for Bob (BEZ06) to correct all the many inaccuracies in that set of "simple" instructions.

Vette5.5

Honestly, I wouldn't call messing around with air pressure an easier way, as had a Bartec tool for years now, and can't imagine anything easier/faster. Since 08', Vettes aren't the only thing TPMS equipped, as all cars are now, and the tool is needed for a simple tire rotation on all of them.

cclive

100%...if you drop the air pressure, it pretty much requires you to have an air compressor to fill them back up.

BEZ06

Hi Ron

No, it won't hurt at all to give it a try. If it doesn't work (you don't get a honk when changing air pressure) then just turn off the ignition and nothing will have been changed.

HOWEVER - if it does work and you get a confirmation honk at the left front, you'll need to continue around and do the other 3 sensors as well.

When the first (left front) sensor is triggered and you get the horn honk confirming that its data was programmed into the TPMS, all the other 3 sensors are wiped out of the TPMS memory, so you always need to do all 4 sensors anytime you start the programming.

But, if you don't get a honk at the left front then nothing was logged into the TPMS memory and all 4 old sensors are still in there.

Each sensor has a unique ID# that is logged into the TPMS. The way the TPMS knows the location of a sensor is because the ID# is transmitted in the data stream the sensor transmits to the TPMS along with the pressure in the tire.

When you perform the relearn procedure to program the sensor ID#'s into the TPMS, the ID# of the first sensor triggered is logged into the TPMS memory as the left front, the second as the right front, the third as the right rear, and the fourth as the left rear.

If you do it in a different order the sensors will still work, but the DIC display of pressures won't correspond to the actual location.

Likewise, as in Seadawg's case, if the sensors are moved to a different location when new tires are put on (or on another vehicle, if the tires are rotated) and a relearn procedure isn't performed, the sensors will work but the DIC report of "Right Front 15 psi" would actually be talking about low pressure in a different corner of the car.

Additionally, the DIC display is a great reference, but you need to use a good hand held gauge to set/adjust the tire pressure. The DIC isn't instantaneous, and in some cases won't display the actual pressure until you start driving faster than 20 mph for a couple minutes.
