2011 LX570 - check tire pressure system (1 Viewer)

[banditti]

My wife and daughter are on an overlanding trip. She just called me and told me display was showing her "check tire pressure system" with no read out on TPMS info. I have googled around and don't really see anything.

4 month old rims, tires and TPMS sensors all from discount tire.

Thoughts?

I’m guessing a bad tpms sensor. It won’t show read outs if one of the sensors goes out.

A particularly horrible design choice. When there is a tire pressure sensor issue it stops showing any pressures. Not very helpful for troubleshooting. Just check pressures with a gauge, if the actual pressures are fine, continue your adventure.

mine just did the same thing, calm down and just replace the faulty tpms sensor. They are just little watch batteries that eventually die.

I'm not spun up, just trying to figure things out. Also, like I mentioned the sensors (and batteries) are only 4 months old. Thanks.

My wife took it into a discount tire and they checked all the pressure and reset the system. We will see if that sticks! Thank you everyone for your willingness to jump in and help!

I got that notification on my '15 while driving through some mountains. Stayed on for about 30 mins, including a restart, then it just went away, never to be seen again. Very strange.

Hit reset button under drivers footwell next time. That will re-initialize the system.

I don't believe hitting the reset button will do anything while it's in a fault state. Similar to @JetFuel, I've had mine trigger 2 hours into a drive, then 20-30 min later go off and not come back. That happened twice on longer drives to me. It's very annoying that it stops reporting all sensors when it looses one. With techstream or a odbII tool you can see the sensors that are still working.

I just replaced mine with what I'm pretty sure are knock off denso sensors, so I'm not looking forward to how fast they will probably fail.

Mine had a Multi-day fault after I too recently had a flat tire. Hit the reset button and all is fine.

I"m sure there are many different failure modes between all the different revisions of LX and LC. Just for my knowledge. Was your system in a full fault where you couldn't see any tire pressures? Or was there just one tire showing low/fault because of the flat tire?

My experience when there was pressure sensors not "talking" with the truck was that hitting the reset button did nothing. As in, holding the button did not trigger anything to change with the TPMS indicator or anything else. Once I had all my sensors working, hitting the reset caused a series of flashes notifying that a reset had taken place.

Correct, no sensors were reading at all.

Weird, really does seem like a poor bit of programming for the TPMS system. Its obviously not going to hurt anything holding down the reset button, so worth a shot.
