: 2012 CTS V TMPS reset question

I switched my winter wheel/tires to summer wheel/tires on my 2012 CTS V. The instruction booklet says to use a GM tool to reset the TMPS. The instructions do NOT give the reduce or raise pressure in tires protocol as a method to reset the TPMS. I tried that anyway and that method DOES NOT work. Why not?? Do I have to go to the dealer? Is there an inexpensive reset tool I can purchase? This is ridiculous--my BMW had a simple reset protocol done by the vehicle computer and driving the car.
Thanks for any help on this.

I don't know 100% about the V, but I highly doubt there is a tool required. My dealer told me that a special tool is required to reset the sensors when rotating tires on my 2010 Camaro and my 2009 Enclave. And considering I have reset the sensors on my Enclave, and switched to a completely different set of sensors on my Camaro, both without any tool, I know the dealer service is guy is either lying or misinformed.

I am sure someone will chime in here shortly with the correct procedure.

So you're saying you held both lock/unlock button down until you got the two beeps (with ignition on), then did each tire clockwise starting with the LF? Raised or lowered until you got the one beep, then went to the next one in sequence? Mine is page 5-79 in my manual. I can't believe that you need a tool either to do this.

I don't know why you would need a tool on the V2 when you didn't in the V1...

There is indeed a special tool for resetting the sensors that the dealers use. I believe it is much faster than the manual method. I think it just replaces the need to inflate/deflate to activate the sensor.

You are correct.

For at home, the resetting method spelled out in the manual works. Sometimes you have to be a little patient after bleeding off 4 or 5 lbs of air, waiting for the horn beep before moving on to the next wheel. I've waited as much as 10-12 secs. After getting the double beep telling you the reset has been done you will have to drive the car briefly for the readings in the DIC to reset.

I've waited as much as 10-12 secs.

When I swapped wheels on my Camaro, I think I waited longer than that for the first wheel.

How much are those tools? If they are less than $20, I think I would gladly buy one rather than inflate/deflate twice a year.

I suspect the tool has been implemented recently with the popularity of nitrogen. They don't want to be constantly deflating and inflating tires and using up nitrogen tanks.

The tool is now necessary for late 2011 and now 2012 model GM vehicles. The reason they state is that in the shops there are too many possible interferences with other vehicles in close proximity to the sensor you are trying to initialize.

Here is some info regarding this:

The tool is available direct from GM service tools/SPX: http://gmspecialservicetools.spx.com/ToolDetails.aspx?id=5677

I ended up getting one just to have around the shop even though all of my vehicles are able to be done with the raise/lower pressure method. This is so much quicker though and will come in handy for the newer vehicles that will be coming thru the shop. I've been lucky up to this point & have not needed to get one for anything that came thru the door. The old method, though slow would always work. Not anymore...

Before I ordered my tool, I called my GM parts dept & he said no luck, order it from the website. Just for grins, I tried looking all over the web first & ended up at the place listed.

Did mine yesterday. It may take up to 10 or 12 seconds of letting the air out to get a beep. The last tire, left rear, gives two beeps to signal the process is complete. I finished by going around and inflating the tires back to their normal pressure. No need to buy a tool. If you feel you need to buy a tool, here's one http://www.amazon.com/OTC-3834-Pressure-Monitoring-System/dp/B003969ANU/ref=sr_1_20?s=automotive&ie=UTF8&qid=1333171432&sr=1-20

There may be a problem for certain late model '11s & most if not all 2012 models though. Other's have tried on their 2012 GM cars and it didn't work.

Worst case is try the old method & see if it works. If not, then you have to do something about the light. Other option is if it is just a simple rotation scenario, just leave it alone. Yes, the tire pressure indications will be incorrect in the DIC, but at least you will have some indication a tire is low, then you just have to check for the low one.

Another indication that you can look for is in the owner's manual. If it shows the old raise/lower procedure, you probably are good. If it shows the new procedure that says you need the tool, you may be out of luck.

The old relearn procedure is in the 2012 CTS/CTS-V manual.



TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code. The identification code needs to be matched to a new tire/wheel position after rotating the
vehicle’s tires or replacing one or more of the TPMS sensors.
Also, the TPMS sensor matching process should be performed after
replacing a spare tire with a road tire containing the TPMS sensor. The malfunction light and the DIC
message should go off at the next ignition cycle. The sensors are matched to the tire/wheel positions, using a TPMS relearn tool, in the
following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear. See your dealer for service or to
purchase a relearn tool.

There are two minutes to match the first tire/wheel position, and
five minutes overall to match all four tire/wheel positions. If it takes longer, the matching process stops
and must be restarted.
The TPMS matching process is:
1. Set the parking brake.
2. Turn the ignition 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.
4. Start with the driver side front tire.
5. Place the relearn tool against the tire sidewall, near the valve stem. Then press the button to activate the TPMS sensor.
A horn chirp 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. After hearing the confirming horn chirp, for the driver side rear tire, the horn sounds two more times to signal the tire learning mode is no longer active.
9. Turn the ignition to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the tire and loading information label.

Looks exactly the same as in my 2009 manual, except the presence of the TPMS learning tool.

Edit: The 2012 manuals are available online.

Looks exactly the same as in my 2009 manual, except the presence of the TPMS learning tool.

Clarification: If it says raise/lower tire pressures-then that will work for you. (you can use the tool as well-much quicker).

If the owners manual says use just the tool (like the 2012 manual shows)-then raising/lowering tire pressures will NOT work to learn the sensors to the car. Tool only.

That OTC tool is geared more towards a shop environment and has the ability to do many different manufacturers sensors. It is also updatable. The small unit listed earlier is $62 and geared for GM vehicles.

It wouldn't surprise me if they start eliminating the inflate/deflate method. As time goes on, fewer and fewer people even rotate their tires. Relying on a dealer or tire shop to do everything. Still sucks though that they are making it harder for us. Were it just for rotation, no biggy for the tires to be displayed in incorrect spots. But what about for those of us who swap tires?

Read it again, the 2012 manual you posted says NOTHING about raising/lowering the tire pressures, just putting the TPM tool against the tire to set it.

I ordered direct from SPX. I called them via the toll free number provided. They are a supplier to the dealers for their specialized tools, no fear as far as ruputable operation. I called because it mentioned to call to order on that specific tool's page, but it would have worked web only. The sales person on their end was very nice and professional. It took less than a week to get to my shop.

(I'll have to remember to keep the tow hook if I sell the V, thanks for the reminder).

I wonder if the people who say it isn't working for them are letting enough air out. It can take 10 seconds or longer before you get the beep. You need to refill the tires after the calibration procedure.

Just out of curiosity, which procedure does your Vagon owner's manual list? Raise/lower pressures or the tool method. What is the build date also.

Build date is first week of January 2011. The on-line 2011 CTS manual pages 10-74 and 10-75 does mention a "relearning tool" to be used in the procedure outlined above. I hadn't read this until you raised the question. The procedure without the tool seems to have worked on my Wagon.
Maybe Cadillac CS can chime in on this question. Difficult to understand why the procedure has worked on previous model years without a tool and now you need one.

I'm thinking the online version is just the most current. The actual paper manual that shipped with your vehicle may be representative of which TPM procedure will work in your particular case. If it says raise/lower pressure that is maybe why that procedure worked for you in the past. If they shipped your car with a manual that says use the tool...

OK, hadn't driven the Wagon since I reset the tire monitor two days ago. I assumed it had taken when I got two beeps on the last tire. I just took it out for a 15 mile drive. No more "service the tire monitor" message. I believe the bleeding tire method and no reset tool does work, at least on my 2011.

If you got the beeps at each tire & 2 at the end you are good. If it didn't take, your TPM indicator would be on and tire pressure readings would be gone.

As far as what I was wondering regarding your owner's manual, I was being just the slightest bit optimistic and giving GM just the slightest bit of hope that maybe , just maybe, they got it right this one time & put the right manuals with the vehicle. I know, just about as much chance as pigs flying (I love that TV commercial with the pig......weeeeeeeeeeeee) Yes, it's been a long day....

I broke down and ordered the $62 reset tool from SPX. I had to call and place the order over the telephone. A little strange these days but no big deal as long as you know the part number of the tool you want--they're not there to help you -- only to take your order! Really no problem. It took 3 months to get the tool because they were back ordered. But suddenly it arrived. Not much communication from SPX during those 3 months but it was the correct tool.

Works great. Took all of about 2 minutes to reset the TPMS. Now with winter approaching I will use it again for the winter tires. For $62 bucks plus shipping -- worthwhile.

One really stupid question. Given how common TPMS Is now, shouldn't this be something the apes at the tire places be able to do?

10-12-12, 12:55 AM
FYI, having becomed concerned that the TPM sensors on my 2009 CTS-V were not assigned properly, and because the owner's manual did specify the tire bleed-down procedure as the method to use, I bled off the right front tire until I received a beep and having determined that the correct wheel was assigned, I quit. I reinflated the tire and the tire symbol in the dashboard remained on. I read the owner's manual and determined that an incomplete tire assignment would cause this. I restarted the assignment procedure, took it to completion, and all was OK.

Now my 2009 CTS-V does give the tire bleed-down procedure and it works. My 2013 CTS-V owner's manual specifies to use the tool and does not give the bleed-down procedure. Whether the bleed-down procedure works or not remains to be seen (my wife has not been home with the 2013 CTS-V enough for me to try it). Also, I don't want to get the tire low/high indication in the dash and not be able to turn it off. The "tool" before was simply a strong magnet and five or more of the Radio Shack circular magnets, which would fit over the tire valve stem, would work quite well. Does the strong magnet "tool" still work?

Well, I am bent. I like doing these kind of things myself like everyone else who does. But where do people unable or unwilling going to go to get a problem like this fixed? The dealer (rape)? With all due respect to people who work hard for a living, If something as standard as TPMS is beyond the skill level of your average joe tire guy, then my characterization holds (snout).

tedcmiller
10-14-12, 12:18 AM
OK, the strong magnet doesn't work. So my next question is does the tire bleed down procedure work for the 2013 CTS-V even though use of the "tool" is the recommended procedure, and the bleed down procedure is not mentioned?

I would like to check the assigment myself because I have had the dealer put on new tires and/or wheels three times on past CTS-V that I have owned and all three times, the wheels were not correctly assigned.

Resurrecting this thread now that I've switched over to my new winter tire/wheel set. I read the 2013 manual and there is no mention at all of the old method of resetting the TPMS monitors, confirming the observation of others in this thread. They specifically and only discuss how to use the relearn tool to activate the monitors, and in which order :( Interestingly, the owner's manual also says to go to the dealer for a reset, or call the dealer to ask for a reset tool. I called the parts department at my dealer and they said "that part is for service departments only and we don't sell it".

So I'll be calling SFX to order the tool tomorrow. In the meantime, my start-up protocol will include ignoring the "service tire pressure monitoring system" message. If there's a backorder as noted by the OP of this thread, I'll have to break down and head to the dealer for help.

Why did GM have to make a simple process so difficult? Was so easy in my 2009 V.

Link to replace broken one in post #49. It's also available on the SPX site for the El-50448 tool under the 'document library' heading. It explains the reasoning behind the requirement for the tool instead of the old way of setting the sensor.
This change took place for GM vehicles manufactured after January 2011 according to the document.
