2007 Toyota Corolla Indirect Tire Pressure Warning Indicator Reset Procedure

This information updates what I talked about in this video, so PLEASE READ:

For the record, our 2007 Corolla LE was manufactured in Canada, with date code 09/06 (09/2006).

After getting new tires, we could not get the Tire Warning Indicator to stay off!

I researched a bunch of websites and videos, and decided more clarification was needed. So, my take on what I figured out. (I'm no expert. I just wanted to get my car fixed!)

First, you need to be aware that there are two different kinds of tire pressure warning systems: Ours is an "indirect" TPM system, where the car's computer monitors the ABS sensors on each wheel. Not like newer cars that have a TPMS sensor on each tire.

With a car like ours:

If your tire indicator light came on, so you added air to a tire, turn the ignition key to ON and press and hold the RESET BUTTON to the left of the steering column until the indicator light turns off. It appears that this should be sufficient. (This is what we tried first, after getting new tires. But the indicator kept coming back on, after maybe 10 miles of driving.)

If you rotated or got new tires, do (what I'm calling) a "full reset":
Turn the ignition key to ON.
If the indicator is on, do the previous step. Then turn the ignition off. Wait a minute, then turn the ignition key back ON.
THEN PRESS AND HOLD THE RESET BUTTON DOWN UNTIL THE INDICATOR FLASHES 3 TIMES. Take your finger off the button.
Leave the key ON for 3 minutes.
Then turn the key OFF.

Two websites I found said to leave the ignition on for a minimum of 3 minutes.Two other websites did not mention this step, but talked about the system needing to be driven for an hour to fully calibrate. Not necessarily all at once.

I don't know which is correct: I did both.

Warning: It sounds like this kind of TPM system will not be functioning normally until after one hour of driving. That is, it will not warn you of a low-pressure tire, like if you picked up a nail, before one hour of driving has been completed. So be careful.

After doing this "full reset", I drove for 75 minutes this afternoon around our area of New Hampshire, 24 miles, and the tire pressure warning light did not come on. Yeah!
