This message came up on the info screen relating to tps, checked air pressure everything was ok, reseted it hasn't gone back on, but las time the tire pressure was low it said loe press, not check system, any input?

I had the same thing happen just 2 weeks ago. The car started warning about the tire pressure but I couldn't find any of the tires low (I checked each 3 times). I was already headed to the dealer for service that day and I asked them to take a look at it. They said ALL of my tires were low (which I find odd since all of them were at the pressure specified in the door) and reset the system.

I haven't seen the message again. Anyone else seen this?

SerKevin, was your tire gauge correctly calibrated? If there were two independent indications that the pressures were low (dealer and TPMS), your gauge may be giving you a false or inaccurate reading.

My thinking is that as the weather becomes cooler throughout most of the country, tire pressures are naturally going to decrease and we'll see more of these kinds of posts. My advice would be to check your pressures at least once a month, monitoring system or no monitoring system.

I am not sure if the 2IS follows full U.S. standard in TMPS regulations.
If so, the tire pressure must stay within 25% of the preset value, or the TPMS module will send out tire warning sign.

There are only few ways to trigger the warning sign.
The tire pressure falls outside the tolerance range.
The module is in low battery mode.
The module is damaged, or can not be detected.

Good luck with your troubleshooting!

What you need to do, is after you've checked and made sure that all tires are at the correct pressures, you need to reinitialize the monitoring system. just toggle through until it says 'Initial'

I did that, the only thing that worries me is that instead of saying low tire pressure it only said check system.

Then I think thats in regard to something else... which requires service to run diagnostics. I'm sure they can figure it out real quick my connecting the car to their handy dandy systems.... But you should take it in and not wait too long....

that happened on my other car, and it turned out the airbags werent working and the seat belt sensor was off too.

I ran into an issue with the TPMS on the drive up from SoCal to Seattle when I picked up my car. I was messing with the computer and set the TPMS to "2nd" I think which caused it to go off when I was driving on the freeway. Checked pressure on all tires at a gas station and found no issues. I switched back and the light hasn't come back since. I think there's something in the manual about this setting. Good luck either way.

Ah, that's why I used 3 different gauges... just to make sure. The one I own, one at a service station half way to work and one of a friend at work. I'd find it odd if all three were off.

Also this is Houston, Texas... it doesn't start getting cooler here till the end of October or first of November.

i just got a (low tire) on my display today also..... the last time i drove the car was 2 days ago... Today, i pull it out of the garage to wash it and it was fine... but when i was done, and backing it into the garage i got the (low tire) warning.

it has gotten cooler in arizona... but i was driving the IS for about 4 days in a row with no problems.. i let it sit for a day and now this comes up.... hmmm?

Yeah if it actually says low tire pressure it really is, just make sure you reset the screen after you fill up on the recommended tire pressure.
