TPMS Sensor Question
I've been meaning to reset my TPMS sensors on my car since I got 20" wheels. The manual says to start the engine, then hold the reset button under the driver side dash until the TPMS light blinks 3 times and the dash display says "Initial Pressure". Well, I did this and left my car running for 25 minutes and nothing happened.
1) Is it supposed to tell me its finished. How do I know it's done?
2) Does the "Initial Pressure" on the display suppose to stay on or does it disappear after 2 seconds?
Also, I want to set the lower bound threshold. So if my 20" tires are always set to 38psi, I want my TPMS sensor to warn me at around 35 psi.
3) How can I set that? Some people have said that you can't do it without taking it to the dealership. I called Cerritos Lexus, and the technician said to turn on your car, but not your engine and hit the button mentioned above until it blinks 3 times. Then let go of the button. Then repeat this a 2nd time. By doing this he said it sets the threshold. Do you know if this is true?
Can someone please help me out?

Why don't you try what the Lexus tech suggested?

The reset worked for me
. I knew it was reset because my TPMS warning light went off after I drove it for about 15 - 20 minutes. See my thread for the method I used to reset to any pressure you want: https://www.clublexus.com/forums/gs-...-pressure.html

I followed your exact instructions, but I don't think it worked.
The thing is that my TPMS light is not on so my light won't go off to tell me it worked. When lowering the PSI below threshold, do I need to drive a little bit for the system to recognize that the pressure is below the threshold? Or will it just turn on as soon as I turn on the car because it recognizes that pressure is low?

. So it definitely isn't immediate.
