No need to go to dealer or buy tpms tool for tire rotation

Hey all. I looked at all the threads and did not see this mentioned. I did my tire rotation today and wondered about resetting the TPMS. I know the owner's manual says to get the tool, but my ex-wife's 2010 Equinox has the TPMS and it allows you to do it without the tool. So, I tried and it worked!

Here's what I did, the first time I tried (more on that in a minute), I had the valve stem covers off, and followed the instructions on the manual except that instead of using a tool, I let air out of the tires just like the Equinox. Well, it worked ok, until I got to the last tire and I ran out of time, thus the TPMS warning light came on.

The second time I tried, I had the tires at 28psi each, repeated the procedure and it worked just fine. The TPMS light was on until I turned the car back of, and on, and it went away.

Just wanted to let you know that there's no need to buy an expensive tool or go to the dealer for this. The process is laid out on section 10 of your owner's manual.

I usually just go to Discount Tire, and they do the rotation and all for free.

I rotate my own tires and I was expecting having to reset the TPMS but I got in my car started and drove. No lights, nothing. No tools req'd for the rotation. As long as the sensors are able to transmit back to the computer and the PSI is correct should be no problem.
Yeah, but the tires will not be associated with the correct corner of the car on the display. It might tell you the RF tire is low when it's actually the LR after the rotation unless you perform the relearn procedure.
all you have to do is go through the re-learn process in your owners manual, and then the "tool" is you letting air out of the tires ;) it will beep the horn when it learns the position

I don't think you looked hard enough as there have been a few threads on this topic, the last one only being about a month ago and yes, letting out the air works.
So, to clarify, using the "letting the air out" method, in order to complete the process within the 5 minutes stated, results in all four of your tires being low on pressure once the matching is complete. Then you just re-inflate all the tires to normal pressure, right?

BTW, thanks for the thread. It served as a reminder that I didn't rematch the sensors after I rotated the tires a few weeks ago. :biggrin:
After this last winter was over & it was time for the summers to go back on,I also followed the owners manual and then I aired the tires up to 42psi. Then performed the 'let the air out' with a small flat tip. All 4 corners done in or around 5mins. :eusa_clap:

...+1, that's how I've been doing it.

Exactly! However, if you don't relearn the sensors, they will still give the correct air pressure in the tires, just not in the correct tire location which is still usefull to let you know if one of your tires becomes extremely low.
How far down are you guys "airing down" to do this? Rotated my tires yesterday and was wondering about this?

So you air up to 42-ish psi, then down to what?

Until the horn beeps...usually 5-10 lbs. I let my air out slowly which I believe gives the TPMS more time to notice the change in pressure but that's just me.

Yes, I pumped mine up to about 39 lbs, but I shoulda went further. I let out air, and then I thought it should have beeped by then, and I stopped. Then after a few seconds it beeped. Afterwards, they were all in the 20s, so I had to pump them up again. Well, next time I'll get the slow bleed right!:)
Cool, that's good info. Will the horn only beep if the key is in the ignition, or will it do the same thing if you are "away" from the vehicle?
Interesting. I did not do anything like this. I just rotated. Hit the reset button on the turn stalk in the TPS mode on the DIC. The DIC stated 'Learning' for about 10 seconds, horn honked, and I was good to go.

All pressures are accurate and indicating the correct tire.

I think the horn honking only means it's ready to START the relearning process.
If all your tires are within 1-2 lbs of each other the DIC will always appear to be correct.

I think I left the key in for the entire procedure....

I don't know. The pressures changed from the previous settings and correspond to my hand held pressure gauge. I usually just have Discount Tire rotate them so I don't think I will be running into this issue much in the future.

Honestly I dont care for GM's TPMS system. Seems to create more headaches than solutions. My Nissan just has a dummy light if one or more wheels are low. I guess I could be the exception since I have always kept a close eye on tire pressures on all my cars.
I had a Chrysler 300 with TPMS and somehow the Chrysler system is able to self identify which wheels are on each corner of the car. In other words you don't have to reset the system when you rotate the tires - the car does it automatically. I have no idea how it works.

Yup, All you need do is that. The beep lets you know that learning has been started. When the dic changes screens, learning is complete. About 30 seconds.
