Low Tire pressure light

[smokin_olds]

I got a flat two days ago and had to put the spare on and drive over the the shop to get the tire fixed. When the spare was on the low tire pressure light came on and i figured it would go off once i put the original tire back on, but the light never went out. does anyone know how to reset the light or what do you think i should do???
Thanks,
Jake

lmao, does anyone know how to reset the light???? theres guys on here who work on their engines everyday, guys who do all kinds of audio shit, body work. No we dont know how to reset the tire pressure lightlollollol

But yea the search button is there for a reason, and SO IS YOUR BOOKLET FOR YOUR CAR. why dont u look there first!?!?!?!? why come on the website and ask when u have a booklet for your car in your glove compartment

sorry i just thought it might of happend to one of you guys, i am new to this so im sorry it was a stupid question.

i dont have a booklet :(

no question too stupid

i dont have a booklet :(

You can download one from www.mygmlink.com

smokin_olds, that was a good question. Not EVERYONE know's what there doing when it comes to cars. A manual would be ideal to get. Very handy. I hope you figured it out. If not, I can help. Probably. ;)

As for just about everyone who replied to his question.. Grow the hell up. People come here to ask question's to problems there having, not to get insulted on there knowledge of cars and this forum. He's new give the guy a freakin break!

I'll give a knowledge as to why the light came on.

According to the booklet that everybody to talking about: The "Low Tire Pressure" light will come on when 1 tire drop below 12 psi than the other 3. Most likey becuase at 12 psi the lopside-ness starts which you always feel when you put on the compact spare (or doughnut as it's sometimes called).

The car's computer deceted this thus bringing on the warning light.

Remember though that if all the tires are underinflated, this will not work

Just for the record, this is the official description of the TPM system.

Tire Pressure Monitor Description and Operation

The Tire Pressure Monitor (TPM) system alerts the driver when a large change in the pressure of one tire exists, while the vehicle is being driven. The TPM system uses the Electronic Brake Control Module (EBCM), Antilock Brake System (ABS) wheel speed sensor inputs, class 2 serial data circuit, and the Instument Panel Cluster (IPC) to perform the system functions. The EBCM contains software to calculate relative tire pressure differences. The software requires approximately 30 minutes of straight line driving in three different speed ranges to complete the calibration process to have full capability for detecting a tire pressure condition. The speed ranges are as follows:

24-64 km/h (15-40 mph)
64-113 km/h (40-70 mph)
113-145 km/h (70-90 mph)
Each speed range has 2 modes of tire pressure detection:

Monitor Mode 1
Monitor Mode 2
The EBCM learns the tire pressure calibration for each speed range independently. In Monitor Mode 1, the EBCM has only partially learned the tire pressure calibration for the speed range and has limited detection capability for a tire pressure condition. In Monitor Mode 2, the EBCM has fully learned the tire pressure calibration for the speed range and has full detection capability for a tire pressure condition. Once the TPM system has fully learned the tire pressure calibration the EBCM monitors the ABS wheel speed Sensor inputs, which will all be the same as the learned calibration if the tire pressures stay the same. If the tire pressure increases or decreases in one tire so to will that tires circumference and radius, which causes that wheel speed sensor input to change. The EBCM recognizes this change in wheel speed as a tire pressure condition. If the pressure in one tire becomes at least 69 kPa (10 psi) higher or lower than the other three the EBCM commands the IPC to turn on the LOW TIRE PRESSURE indicator via a class 2 serial data circuit. This indicator does not appear if more than one tire is high or low, or if the system is not properly calibrated. The system does not alert the driver to which tire is high or low. To turn off the LOW TIRE PRESSURE indicator, refer to Tire Pressure Monitor Reset Procedure .

turn the key to "on" (don't start the engine) and pump the brakes 3 times to reset the light.

Just take off the fuse panel and turn the key to the on position without starting it; hold the red reset button until you see change oil light flash release and then tap the reset button so that tire pressure light blinks then hold down until you hear a ding. start driving

What he said. lol I had to do that two or three times.... got a screw in my tires a couple times..

Not all the aleros have the reset button. I think the newer ones are the ones without it. Mines an 01 and I have the reset button.
