Lexus sc430 tire pressure monitor

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?

Testimonial: "Knowledgeable expert...found the button (but unfortunately did not fix problem--maybe shop messed up a sensor in the tire)"

    Thats for switching between summer and winter tires, not for resetting the warning light.

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.
Cheer.

They might have broken one of your sensors, if your yellow light stays on without making and beeps, there is a malfunction reading the sensor. Hope this helps.

The SC430 tire pressure sensors are sensitive to both higher and lower pressures than are allowed. Make sure your tires are not over-inflated.

The tire pressure display is still on my dash even though I put air in my tires. How can I remove it?


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.

Lexus tire pressure monitoring system


Hello,

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.

Thanks,
Luke

After putting the correct preasure on the tire and resetting the tire preasure light it's still on


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.

Tire pressure monitor light staying on


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 check tire pressure light and ABS auto traction sensor light keep coming on. Tire pressure is good


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 steps:

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.

Low tire pressure indicator remains on in Sc430


Either your pressure indicator is bad or the tire gauge you used is bad. Don't go by what the air pumps say, use a decent tire gauge.

Lexus ls430 2004 tire pressure indicator


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.

Good luck.

Dashboard light


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..

Thanks,
Steve
