Check all tire pressures then reset your TPMS.

Uhmm heres the most stupid question of 2010, how do i reset it, when i press it, it says Tirecontrole inactive..
:dunno:

Sounds like maybe a wheel speed sensor going out- if you already tried to reset it.

get them to the pressure they are supposed to be (cold.) With the key in position two, press and hold the tire pressure monitor switch (to the right of the steering wheel on the dash) until the confirmation message appears in the dash display. The system will now warn you when the tires deviate from this pressure (by how much, I don't know - does anyone?)

It sounds like you have a bad wheel speed sensor. The sensor may actually be bad and require replacement, or it may simply be disconnected or have debris. You can pull them out, clean them and the connectors with TB or electronics cleaner and see if that takes care of the solution. It worked for me as my right rear wheel sensor had come loose and grime had worked its way into the connector.

find someone in your area who can use NCS Expert. very simple to disable, change the zcs to remove RDC then remove the module and the switch. then deposit them in the closest trash can.

So I have done this as per the manual.
However, it does not say anything about checking it manually.

Is the button supposed to display anything special after I did the initial tire pressure setting?
Even after I did the initial tire pressure setting, when I press the tire monitor button again, it always says Tire Control Inactive, but I have never received a warning light.

From what I read, I believe the tire pressure monitoring system isn't a standard TPMS, but I'm not sure if the display is supposed to display anything at all for 'good tires'.

Thanks.

If you read the manual, it only displays "Tire Defect" when there is a mismatch in wheel speeds (ie a flat or underinflated tire).

Nope, i calibrated the thing and now its fine... no more irritating message... thx!

Haha what a coincidence, I got that warning light tonight! I was a little worried as I have never seen it before and dont have the manual. I took it to a gas station and got the tires all up to pressure and it went away when I restarted the car

That IS a coincidence

What PSI was it at when it went off and what did you fill it up to?

I'm not blackxs, but had the warning happen to me a couple of years ago. I stopped and checked visually, but the tire didn't appear to be under-inflated, so I drove the short distance home. Checked it in the morning and it was around 20 psi (I normally run 42 psi in the rear). So the system worked for me.

Turned out I had a nail in the rear tire.

Sounds good. Thanks for the feedback.
