Need some help how do you make the service tire light go out on a 2012 Silverado? I don’t have a low tire It came on out in the middle of nowhere last night darker than **** stopped tires looked ok made it in to town checked air one tire was about 28/29 aired it up light stayed on made it home this morning checked tires all good jack the pressure up a little light still on brought them all back to 34/36 light still on called dealer no mechanics in .
 
My 08 gmc resets itself. Check manual?
Bad sensor? May try disconnecting
battery hot cable for a few seconds.
 
cold weather brought mine on. GM mechanic said to air up the tires about 3 lbs above the guideline. he went on to speculate that tire gauges aren't very accurate.
 
Larry - Check the owner's manual. My wife's '03 a low tire pressure warning must be manually reset using the radio controls - it will never go out otherwise. Your '12 may be similar.

The low tire pressure reset is hidden somewhere in radio a system sub-menu.
 
My Jeep has to be reset after it comes on, look in manual should tell how to do it.Still can be a bad sencer also check the spare tire it maybe low.
 
Have 06 Chevy Impala and if tires are over inflated the light will also come on. On the Impala if they drop to 29 lbs. or over 33 lbs. the light comes on.
 
Battery wont do it . Need to relearn TPS monitors . should be in owners manual . or you have a bad sensor . Be sure to check spare tire .
 
If it really bothers you put some black tape over it. There's a reason the term "idiot light" came into being. Seriously not sure about tire light but I was told that on a 2004 Chev PU you could reset your Change Oil Light by when first starting engine rev engine 3 times quickly. haven't had opertunity to verify that but heard it from 2 different sources, 1 a mechanic freind whom I trust. Might work or it might not. Like they say 2 cents worth. Rocko.
 
I had that happen on a Mercury Mariner. Owners
manual said that the light would go out after
you drove a few miles..mine went out after 12
miles.
 
Do you have onstar,they can tell you.Mine did that after i put in ethenol fuel.
 
Several GM vehicles have different ways to reset the tps. Some are through the radio controls, some are through the light and dimmer switch, and some are through the light and emergency pedal being depressed. Best bet would be to check your owners manual. The local parts store in town has a signal reader that they can walk by each wheel to determine if your sensor is bad. May want to check that out too.
 
Some sensors are a small unit inside the tire and part of the valve steam. Small battery in it. They say they will last five years or so. There is going to be a lot of them start going bad. I have one in my 2008 jeep that is sounding off.
 
Most tire shops can reset them for you. They are mounted in the
valve stem, I had them reset last year where I buy my tires.

Do this with the ignition on, pedal to the floor 3 time within 5 seconds, engine not running.
 
Some vehicles don't use wheel sensors, they measure the wheel speed through the ABS system and if one wheel gets to turning too much faster than the others it triggers the light.

You may have to go in on your puter controls and reset the tire settings. Should be on your dash monitoring system.
 
Set your parking brake, turn the ignition key to the on position. If you have the keyless remote to lock/unlock your doors, press both the lock and unlock buttons at the same time and hold. The horn should blow once.
The computer is now in the learn mode, start with the left front tire and slowly let the air out until you hear the horn blow again(may take up to 10 seconds). Now move to the right front tire and do the same thing until the horn blows. Move to the back right and on around to the last tire. Once the horn blows on the last tire, you should have a message the TPS has successfully reset.
Reservice the tire pressure and roll on.
If you don't have the keyless remote, it should be the same procedure with the exception of pressing the remote buttons, turn the light switch on the left dash to the left 4 times, the horn should blow once. Then perform the same procedure for all four tires.
 
Take it to your dealer. If it's a 2012 chances are it's still under warranty.
 
Larry,
Kyle has it right for the re-learn. If it is a 1/2 ton it the monitor should kick on around 27-28psi. I would add a few pounds like you did for the winter to stay away from the lower limit.
Door sticker should say 34psi.
I have seen a few instances where it takes more than one time to re-learn the sensor.

if it says service tire monitor system then it needs to be looked at by the dealer under warrenty becouse you more than likely have a faulity sensor if it says low tire then it may need to be reset as others stated
 

All of this just because a few Ford Explorer owners couldn't be bothered to check the air pressure in the tires periodically. Next thing you know the vehicle will go into a total shut-down mode just because the license plate light has burned out.

If someone were to design a software program to install in a vehicles computer system that would basically tell the computer to ignore all but most serious engine problems, that person could probably become wealthy.
 

Those "Tire Pressure" warnings are almost as effective as the "Ck Engine Light", for making Car Dealers more MONEY...

Just more crap most of us will NEVER need...

Ron..
 

I noticed its a new truck Guess it has those low profile tires on it. Low volume of air in them. Loose just a little and the pressure goes down several points.
 
If a tire is low, it will be turning more RPM than the others.

The computer can use the info it gets from the ABS wheels sensors to figure that a tire must be getting low, because it is spinning faster than the others.

Yes, some vehicles DO use the ABS info to monitor tire pressure by comparing the RPM each tire is turning.
 

Yep, and not just lower or higher pressure, it will turn on the idiot light if there's any lump, flat spot, belt separation, etc. on said tires, based on a comparison of all the tire's rotation. My little Chev. Aveo does that. I've had it happen on occasion.
 

Guess you thought wrong. Law Suites can originate from the low end as well as from the high end. These only came about with the exclusive of these little low-profile tires that can lose a lot of pressure at very low volumes.
 
If it says "Service Tire Pressure System" in the info display, the system has detected a problem and a DTC has set. It will say words to the effect of "LF tire pressure low" or whichever position is low. Rotating the tires and not re learning the positions does not cause any problems other than you have to check the other tires until you find the one that's low.
 

On my '08 GMC 1/2ton moisture in tire and toohigh psi has made the service-tire light come on. I know the lack of a spare tire on my truck doesn't affect the light
 
When the 'idiot' lights pop on, I have had success a couple of times with just turning the ignition key on and off 3 times.
