apparently you can reset the tpms without the tool. i found this on another gm site and since mine are programmed i cannot try it but if someone is in a bind and wants to try it and let us know if it works that would be great! apparently you can trigger the sensor by dropping the air psi while the TPMS is in learn mode.


Each TPMS sensor has a unique identification code.

Any time you rotate your vehicle's tires or replace one

or more of the TPMS sensors, the identification codes

will need to be matched to the new tire/wheel position.

The sensors are matched to the tire/wheel positions in

the following order: driver side front tire, passenger side

front tire, passenger side rear tire, and driver side rear

tire using a TPMS diagnostic tool. See your dealer for

service.

The TPMS sensors can also be matched to each tire/

wheel position by increasing or decreasing the tire's air

pressure. If increasing the tire's air pressure, do not

exceed the maximum inflation pressure indicated on the

tire's sidewall.

To decrease air-pressure out of a tire you can use the

pointed end of the valve cap, a pencil-style air pressure

gauge, or a key.

You have two minutes to match the first tire/wheel

position, and five minutes overall to match all four tire/

wheel positions. If it takes longer than two minutes, to

match the first tire and wheel, or more than five minutes

to match all four tire and wheel positions the matching

process stops and you need to start over.



The TPMS sensor matching process is outlined below:

1. Set the parking brake.

2. Turn the ignition switch to ON/RUN with the

engine off.

3. Press the Remote Keyless Entry (RKE)

transmitter's LOCK and UNLOCK buttons at the

same time for approximately five seconds. The

horn sounds twice to signal the receiver is in

relearn mode and TIRE LEARNING ACTIVE

message displays on the DIC screen.

If your vehicle does not have RKE, press the

Driver Information Center (DIC) vehicle information

button until the PRESS V TO RELEARN TIRE

POSITIONS message displays. The horn sounds

twice to signal the receiver is in relearn mode and

TIRE LEARNING ACTIVE message displays on

the DIC screen.

If your vehicle does not have RKE or DIC buttons,

press the trip odometer reset stem located on the

instrument panel cluster until the PRESS V TO

RELEARN TIRE POSITIONS message displays.

The horn sounds twice to signal the receiver is in

relearn mode and TIRE LEARNING ACTIVE

message displays on the DIC screen.

4. Start with the driver side front tire.

5. Remove the valve cap from the valve cap stem.

Activate the TPMS sensor by increasing or

decreasing the tire's air pressure for five seconds,

or until a horn chirp sounds. The horn chirp, which

may take up to 30 seconds to sound, confirms that

the sensor identification code has been matched to

this tire and wheel position.

6. Proceed to the passenger side front tire, and

repeat the procedure in Step 5.

7. Proceed to the passenger side rear tire, and repeat

the procedure in Step 5.

8. Proceed to the driver side rear tire, and repeat the

procedure in Step 5. The horn sounds two times to

indicate the sensor identification code has been

matched to the driver side rear tire, and that the

TPMS sensor matching process is no longer

active. The TIRE LEARNING ACTIVE message on

the DIC display screen goes off.

9. Turn the ignition switch to LOCK/OFF.

10. Set all four tires to the recommended air pressure

level as indicated on the Tire and Loading

Information label.

11. Put the valve caps back on the valve stems.

That is awesome! That is the same procedure for resetting the TPMS on my wife's 2009 CTS!

saves a trip to dealer thanks

If I recall correctly, this has come up before and does not work on the Vette

AFVETTE

the instructions work on some other GM vehicles (Cadillac is one) but not on the C6 TPMS. Don't know why GM chose to do this considering how beneficial this would be to guys that track their vette's.

As usual GM goofed up on something so simple.

It does for MY2010 and up. They changed the sensors over for the 2010s. For MY2005-2009, you still need the tool to do the relearn.

i guess we are still beat but i saw the info and thought i would share sine i had never heard of that before. oh well, i guess no harm no foul.

mousecatcher

this is the same as using a tool. it works because when you increase the pressure (i thought it was only 3# but maybe it's more) the sensor transmits. the tool just forces the sensor to transmit without a pressure or temperature change.

in my experience, even letting air out for 5 seconds is not nearly enough of a pressure change to activate the sensor; unless you do it by unscrewing the valve core! inflating for 5 seconds is definitely not enough.

Note that this technique (or even using a tool) will not work reliably if the car has just been driven because all the sensors are now transmitting too frequently. You have to reset them when they are idle, so that an out of order transmission doesn't occur.

mousecatcher

you can reprogram the sensors at any time. (but taking into account what i said earlier about the sensors needing to be in "idle mode").

AFVETTE

I just checked the 2010 Owner's manual and on page 6-78 it says

"TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
Any time you replace one or more of the TPMS sensors
or rotate your vehicle’s tires, the identification codes
will need to be matched to the new tire/wheel position.
The sensors are matched to the tire/wheel positions
in the following order: driver side front tire, passenger
side front tire, passenger side rear tire, and driver
side rear tire using a TPMS diagnostic tool. See your
dealer/retailer for service."

The 2010 Owner's manual makes no mention of the procedure you mention. Can you point us to an official GM/Chevrolet document that says leaking air pressure re-links the TPM sensors?

Tom

jvp

Nope, but if I can't, does that mean it's not true? Someone here on the Corvette Forum has a 2010 GS, he goes by "GSRandy". He's already verified it works via air pressure gain or loss.

Also, why would GM change the part for the 2010 Corvette's TPMS if it weren't true? See any of Gene Culley's parts posts to verify that they have changed. The important bit is quoted:

AFVETTE

I didn't say it was untrue, I'm just pointing out what the Official GM 2010 Owner's Manual says. If it's in error than we need to point that out.

The TPMS tool still works, and is what GM technicians are still trained to use (per the Helm manual). It's a lot faster than letting air out of the tire or pumping air back in. Consider this an added bonus for end users, so they're not forced to buy a $2-300 tool.

Some of us changing out between track tire's have been doing this for some time now. No matter the proceedure's availible, using a reset tool is much faster and the better one's will diagnose the sensor's, even if off the car. I can just scan the track tire's sitting in the basement with my Bartec, and will tell me if they're functional. Easily found a bad sensor on my brother's 08' Cadillac CTS too. Since all car's 08' up have TPMS, think it's worth spending the money, as you could waste all day dumping air just finding out later you have a bad sensor.

z06Scot

Where can I purchase a reset tool that can diagnose the sensors?

Silver05GTO

I just bought this tpms tool from tirerack, $113.xx shipped

Vette5.5

Not 100% sure, but think the basic Ateq VT10 unit Tire Rack sell's is strictly an activation unit, as doesn't test the sensor's like the pricier unit's. Check around for some of member's BEZ06(Bob) post's, as he's the TPMS guru here and helped steer me to a good Bartec tool a few year's ago. Katech(Jason) used to sell a basic Bartec tool, but can't get em' anymore. Last I saw, some vendor's were selling a nice green looking OTC unit for a good price. Maybe check around for that one. Later found the tool to be an OTC TIPS003A, and some places are selling it for less than $100 buck's.

z06Scot

Yeah, thats the one I'm looking for, the only places I have found that are selling them don't ship to Canada.

VNAMVET

.............correct............did not work for me on any of my past Z06's.

Z06Pops

Thank you. Track my Z06, change wheels a lot, bought the tool and now I can use it. This is a great forum.
