Go back to COMG- The Cruze Owner's Maintenance Guide

This tutorial is only applicable to Cruzes manufactured in mid-2012 and older. All 2013+ Cruzes will require a relearn tool to correct the TPMS sensor locations.

The
TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire’s air pressure. Personally, I start this procedure by inflating the tires to the maximum as shown on the sidewalls. You will see why when you do the matching process. Also, if a horn chirp does not sound after 35 seconds for any of the 4 sensors, turn the ignition OFF to exit the learn mode and repeat the procedure from step 1.

1. Set the parking brake.
2. Turn the key to run (do not start the car).
3. Using the control on the stalk, press the menu button to get to your tire pressure readings.
4. Press clear to reset. Your horn should chirp twice.
5. You have 2 minutes to match the first tire/wheel position and 5 minutes to complete the procedure.
6. Start with the driver side (left) front tire. Deflate the pressure until the horn chirps. Yes, the pressure will get really low, which is why I inflate to max before I start. Also, it takes a few seconds for the system to catch up.
7. Move the to passenger side front tire. Repeat.
8. Move to the passenger side rear tire. Repeat.
9. Finish with the driver side rear tire. When complete, the horn will sound twice.
10. Refill your tires to whatever pressure you run (I'm staying away from this one).

One thing that I noticed happened to me twice is that when I got done, the Engine light came on. However, after driving the car, it turned itself off. Not sure what causes this. Also, I noticed that when the engine light was on, the remote start did not work. Again, it resolved itself with no issues.

Hope this helps.

It's easier to just go to the dealer and have them relearn it for you for free. We do it all the time. They have a special tool to do it with. We get them for like $40 I think, not sure if they're available to the public.

Are you talking about the CEL when the key is on, engine off while you're learning the tires? If so, that's supposed to happen.

While I have a great dealership, I prefer to do it myself as it is an easy process.

Um, I know it should be on when the key is on with the engine off. The CEL comes on stays on until the key is cycled a few times or the vehicle is driven for a few miles. Even the self check does not reset it right away.

No problem, just putting that out there for some people that might think that's a complicated process.

Ever check to see what the CEL is? Obviously that's not normal.

I asked about that and the dealer said the tool would cost 500 , Where do you get yours ???

Also the Owners manual said to use a relearn tool...

So GM changed this so their dealership service monkeys could do it correctly. Talk about least common denominator.

...hey, Cleck! is this Kent-Moore unit (EL-50448) the one you're talking about?:

...and, this is *why* the manual 'drop-pressure' relearn process doesn't work on the 2012 Cruzes:

Hot Tip
Never heard of this "drop Pressure " relearn process .
Kinda good to know This is much cheaper than what the dealer told me ... On the older stuff you can do this with a scanner and a magnet

The manual 'drop-pressure' relearn process does work on 2012 Cruzes (at least early ones). I have done 3 rotations so far in the 26k that I have on it. I took delivery of mine 10NOV2011. (sequence number is 148182). I do it on my 2004 Tahoe and when I saw it was not in the Cruze manual, I decided to try it. The last rotation I performed did not give me a CEL. I was hoping it would so I could have had Onstar diagnose it.

I tried the pressure drop method on my '12 to no avail... So I purchased the Kent-Moore EL-50448 on EBay and it worked great. I completed the re-learn process in about 20 seconds.

So what exactly will happen if you rotate the tires and don't do a re-learn? Will it just show the tires psi in their old location? Or will it cause a CEL or something?

Yes it will show the tires psi in their old location. So it wills say front left is 30 PSI when you go to front left it at 35 and the 30 PSI is on the back left where you just moved it to. It will not throw a CEL just display the wrong PSI location. If you check you PSI often with a gauge(or all your tire PSI are the same no big deal! Just use the TPMS to let you know if a tire is low. Knowing you have to locate it. Kinda like in the old days with my 2002 Alero that used the "stance" of the car to say a tire is low. Never told you where.(Hey it was the stone age!)

Is this something that should be done when I rotate the tires on my '13 LTZ?
Only if you want to know the correct tire position as stated in an earlier post. If not when it says left front is low then it is really the left rear, until you rotate them again.

This method posted by the OP is good only for early 2011 and older after that it requires a tool.
