2006 Highlander Low Tire Pressure Indicator

[LindaSue4T9]

Bought a 2006 Highlander and the tire indicator light was on. Dealer turned off indicator after checking the car and finding nothing. Light came on again. Problem was found and fixed when a slow leak was discovered in the tire that was caused by a nail. Had 5,000 mile checkup and light came on again after about 10 miles. Took the car right back and was told it was probably due to the rotation of the tires done in a 5,000 mile checkup. Turned light off and about 25 miles later the light came on again. Tire pressure in the tires are from 32.5 to 34.0 (put in by Toyota). Is there an underlying problem for these cars to have a indicator that has a problem?

There are two ways to reset the indicator light - the first is to hold down the button (hidden under the dashboard next to the steering column) until the light goes out. That's a reset.
There's also a reactivation, you hold the button until the light flashes three times and then release, that's for use after a wheel is changed, etc. Make sure they have done the reactivation, not just the reset.
If that doesn't work, have them check the technical service bulletins.

Good luck,
Dorothy

Not sure if you've read this before, but did the dealer check the spare, just about everyone gets caught with this one once.

Beg to differ... Reactivation or Reset... same thing when yu simply press the Reset Button. It will simply recalibrate the TPMS ECU.

Yes in one example with the low PSI light ON, pressing the button will put out the light. But, pressing the button after a rotation or air pressure adjust will merely recalibrate the TPMS ECU like the above as well.

The button just Recalibrates in any situation. Remember that the H/L TPMS is an Indirect Type system.

Everyone gets confused on this. I see it all the time.

The Highlander uses an Indirect Tire Pressure Monitoring System versus Direct type.

There is NO transponder in the air valve. The H/L uses a plain tire old valve. Thus, there is no PSI reading done by this Indirect Type System.
It uses the ABS speed sensors to calculate differences of tire rotational speed among the Four rolling tires(the Spare IS NOT included).
When the spare tire is put on, say when yu get a flat tire, the TPMS button must be pressed. (Recalibrated)

Direct Type TPMS costs more for Toyota and only puts it on select models. i.e. the Land Cruiser...
But for Toyota, the Indirect System meets DOT's TPMS mandated minimum Requirements for 2007 vehicles.

The Direct type system uses a transponder/PSI reader type Air Valve on each tire(including the Spare). Each of the 5 tires send a reading of the PSI to the reciever in the Vehicles TPMS ECU.
It has a small battery and is self powered. Battery must be replaced when yu replace your tires. It must be carefully mounted. Each tire has it's owner frequency channel and ID. for it to be recognized by the ECU.
This system is more precise. But has it's own set problems as a result.

It is the original design TPMS going back to the 1980's introduced with the Corvette and the Runflat Tire option.

I have the same thing.

[mrtundra09]

just bought a H/L with the same problem. Mike Shaw Toyota here in Corpus Christi,Texas said it was the spare. Check the pressure on the spare breugel.

you have to follow the owners manual steps exactly or it will come back o n

[trollies00]

i have read the manual and followed it to the dot. My tires are fine and with correct PSI checked every morning. But it comes back within 5 miles of driving everytime. Is resetting battery a good idea? take battery off for few minutes and connect it back?
