The tire pressure monitor dashboard light came on even though the tire pressure is correct. How can this monitor be reset or turned off?
2002 Lexus SC430 with tire pressure light permanently on (after flat repaired at local shop). Pressures within tirs are normal. There is not a spare tire in the car. The shop that repaired flat said I need to go to Lexus dealer to have computer reset...more than cost of flat repair. Is there anything I can do to reset the light?

Re: Lexus sc430 tire pressure monitor
Try this and it might cost you nothing...Remove the battery negative terminal for about 10 minutes, put it back and let the car idle for about 5 minutes then go for a road test and see what happens...hope it works for you. Let me know if this does the trick.

If your tire pressures are all ok and the light is still on the dashboard, either one of two things is wrong ( assuming your tire pressure gauge is giving you correct data)
1 - A battery or one of the tire sensors (4) in a tire is mis functioning
2 - Something wrong with car electronic monitoring system.
Check with Hyundai if there is some sort of "reset" that you can perform. On my 2011 Sonata once I correct the pressure the light goes off. U might have to go to the dealer. Just hope your dealer is better than mine.
It would help to know what year and model your Lexus is to better assist you. Typically if you haven't done anything to the car or tires, it may be low on air if the message is "low tire", if message is "check system" or "service tpms" then it may be more involved like a bad tire sensor or other system malfunction. Let me know more info and we can go from there.
Don't spend money taking it to a mechanic or dealer. Lower the spare a correct the pressure in it. Then reset the pressure light. All these Lexus tire sensors are little transmitters sending a signal to your car's receiver. Had the same problem and solved it this way.
the dealer will have to do it its a program in the car computer that is set up to monitor tire pressure since you changed the pressure the computer knows the change and is letting you know there is a possible leak.you can have it altered at the dealer only.
The tire pressure monitor detects any changes in the tire inflation
pressure. Therefore, it must initialize and store it in its memory if
the tires or wheels have been replaced, re-inflated or the tires have
been rotated. You should be able to re-initialize the system by following these
1. check and make sure that your tires are inflated to the correct pressure
2. turn the ignition switch to the ON position. If the low tire
pressure warning light comes on, push and hold the tire pressure
warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns
off and then release the switch.
3. now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.
4. initialization is *not* completed until driving at the vehicle speed
of 19 mph or over for more than one hour. the tire pressure monitoring
starts when initialization is completed.
Veve713: You probably didn't need new tires unless you had some miles on it. Remember that the spare tire also has a pressure monitor as well. It most likely is causing the low tire pressure light on the dash and only needs to be inflated back to what ever your other tires are set to. I had the same problem on my RX and took it back to the dealership where they told me since the spare is exposed to the same elements (it's under the back of the RX - you have to use the tire iron to let the spare down), it will inevidably lose air.
For Lexus the ! symbol usually is low tire pressure that's all there's sensors in each wheel that report to the car that the pressure is low, also if your wondering how much air to put in the tires you can look by opening up the driver or sometimes the passenger side door and look along the door there's a label that will tell you each tires recommended pressure. Any other questions just ask and id be glad to help you folks, and if you don't mind if you can rate my answer if you get a chance it would be greatly appreciated..
