Tire pressure monitior

I have a 2015 GMC 2500. It has a display that shows tire pressure in each tire by position. When you rotate tires does that confuse the tire monitor.?
 
I think you need to let air out of the tire until the horn blows or chimes sounds, then air up to proper pressure. Should be in your owners manual.
 
I was just talking to a mechanic the other day about this. He said GM vehicles have to be reprogramed with a tool. Dodge, Chrysler vehicles will reprogram them selves after you recycle the key and drive about 15 miles. Fact or fiction I do not know.
I do know you have to be reprogramed with GM.
 
> Thanks, I'll visit my GMC dealer as they are the ones who rotated the tires.

Speaking from experience, dealers sometimes forget to reprogram the TPMS after tire rotation. In my case, they did a tire repair at the same time as the rotation, so that's probably why they overlooked the TPMS.
 

No it still thinks the tires were were they were before you moved them.

If a GM dealer rotated the tires I would think they preformed a relearn... Some as EZ as pie others its like chinese arithmetic.
 
That process does not work after 2012 models. GM felt the need to complicate a system even more.
 
Might be a good idea to lower a tire and see what the dash says. A dealer is always going to say reprogramming is part of the service, but I find at my shop it rarely gets done at a dealer. Local dealer chain feels the need to compete with Walmart on price, so a basic LOF and rotate is something like $29.95, stupid low. They recoup their loss by not paying their flat rate tech properly for the work. He gets half of what it should pay, so the customer gets half the job. When I started at the local Chevy dealer, we were paid .8 hour for LOF and rotate. The current owners bought it, now the same job pays the tech .4 hours. I don't work there anymore, didn't feel the need for my family to contribute to someone's Mercedes and country club fund. I went out on my own.
 
I guess I just assume that the dealer does it, they change the oil (dexos) rotate the tires and wash it for less than $40! But I have never had a low tire so I don't know, If I ever do I will find out. As long as it tells you that there is a low tire you can find it yourself! We have a 85 year old lady friend who had a message on her car last summer, low tire, so she took it in and got it fixed, she thought it was a great option. She probably never would of noticed it otherwise.

Here is a good offer are it was to me hope the link works. All I have used it for is to program sensors I am sure it will help with resets. If you program a new sensor from the old no relearn needed as long as it goes back were it came off the vehicle. They also have a tech line at least you can talk to a real person.

The bad part about TPMS is more shops know little about it than those that do. Customers give up on it thinking there system is to problematic when all it needs is a reset/relearn.

Its cost me a few thousand to tool up I don't give it away. The local Goodyear shop does why I dunno. They get $55 to install a new sensor and do a relearn :shock: They can make a mess out of it.

Since I usually rotate my own, I never bother with the relearn process. If a tire shows low, it is usually not rocket science to determine which is the low one, but I believe the spare is usually also in the equation so do not forget to check that as well. For the most part, I do not pay much attention to the monitor aside from checking pressure on all. If it were not for the aluminum rims today, I would do my own tire service period, and do so now on the steel rims on my daily driver. I just purchased a small balancer so that I do not have to "bother" or inconvenience these guys at the shops, nor pay their rates. When I can, and on my driver with the steel rims, I purchase tires online, mount and balance myself, and not only saves me a ton of $$, it saves me a lot of time believe it or not. I had a guy leave a really bad taste in my mouth when I carried in a set of 4 for balance (only) and he charged me the same as if I had him remove rims, dismount, mount, balance and put on the car. He lost my business going forward, and I realize he was doing this as punishment for not buying tires from him, but he does not realize that he is chasing off potential customers in the process as I will likely never do business with him again.
 
Mine (07 Impala) was impossible to relearn after tire rotations because of what I suspect was a low battery in the sensor(s). I fixed it with a a strip of black tape across the nagging flashing light. TDF
 
Agreed. The current Chevy has a pretty easy TPMS according to my tire man. Early units were a giant PIA.
 
Yes. I do my own rotating and after doing such who knows which tire position low. So with the warning received, I just check all and find the low one and air it up.

On the monitors if anybody is interested, I just re-shoed my 2011 Silverado with 6 years and 30,000 ish miles. Tires still had good tread but 6 years is long enough.

I asked the home town, 5th generation, have any kind of tire for any purpose, guy who survived all the "tire shop on every corner" syndrome as of late, about shouldn't I replace them with the tire change rather than on a onsey-twosey basis later on. Answer was no, wait. He said he'd put it in for me and check the balance if I had a battery go dead. Said that there is no set rule. Has had some over 10 years and still kicking. So, I decided against it and that's that. He has a code reader that resets the trucks computer for the right code per the correct tire.
