reset tire pressure light on LX570

............and what about the reset tire pressure light?

What does your owners manual tell you to do?

What year is the truck?

Check the tire pressure. After re-inflating, drive a few miles and it should go out. There is no need to reset. If it does not help, one of the TPMS sensors can be faulty.

On my 2013 LX570 there is a tire pressure monitor reset button under the dash, in the vicinity of the gas door and the hood release. It isn't easily found just groping around, but if you look you can spot it.

Here is a link to a youtube video about how to do the reset.

If the tire pressure is O.K. and the light is still on, it's usually a faulty TPMS sensor in a tire. I use Autel MaxiTPMS TS501 for TPMS diagnostics. If you own more Toyota or Lexus cars, it makes sense to buy one.

TP sensors tend to go bad after sometime (each has a battery inside which cannot be replaced - u have to replace the entire TP sensor, and will need to 'register' the sensor to the ECU afterwards). So there's really no need to 'reset' the TPMS. If the TPMS light is on, something's wrong. Some TPMS light will lit up not just due to low tire pressure / faulty TP sensor(s), but if one of multiple tires are over inflated, that'll also trigger the TPMS light to lit up.

The Lexus owner's manual is not especially clear about all this, and the procedure described isn't exactly what occurs (at least on my '17 LX). After pressing the reset button, the tire icon light does flash 3 times, but the display doesn't automatically switch to the TPMS display and show "---" until pressures are available. Pressure readings never appeared for me with the car parked.

My understanding is that the correct tire reference pressure that's posted on the tire info sticker (driver's side B-pillar) is factory programmed (in my case 33 psi on all 5 tires). Resetting the reference pressures shouldn't be necessary unless you mount new tires on the OE wheels/TPMSs, and the new tire pressure spec differs from the OE spec. In this case, you air-up the new tires to the recommended pressure (let's say it's 40 psi), and then perform the prescribed reset so that 40 psi is the new reference pressure. After resetting and driving 10 minutes, you can check the TPMS display, and the new pressures will be displayed.

Registration is what pairs the TPMS sensors to the ECU so that pressure readings can be accessed. The OM says "see your Lexus dealer", but any tire or wheel shop that sells TPMS sensors has the equipment to do this registration. I bought a set of 20" alloy wheels, tires and TMPSs to replace my LX's 21" OE alloys and OE Dunlop tires. The tire shop took care of everything and the system has operated properly for 2 years. I recently re-mounted the OE tire/wheel set, and was concerned that I would have to have the OE TPMSs re-registered in order for them to work. I did the change-over, performed a reset and drove about 6 miles, and the OE TPMSs provided pressure readings on the instrument panel display. My conclusion is that the LX is capable of storing 2 sets of TPMS registrations (the way that it should be). Many people who buy premium vehicles and drive them year-round change tire/wheel sets seasonally, so storing 2 sets of registration codes makes sense and convenience. BTW, I searched for information about multiple sets of registration codes, but could not find any definitive information. One post said something about one Lexus model that has a 2-position switch in the glove box that you flip for different tire/wheel sets, but no such switch in on the LX, nor should one be required. I'd like to hear from others with experience on this topic.

That was the OPs only post, it was very helpful 😂
