Default Tacoma tpms reset

I went up over 4,000' in sub-freezing weather and noticed my 2007 Tacoma
tire pressure light came on. Checked the 4 tires on the ground - saw no
problem and continued on my way. A couple of days later, back at sea level
and ~60deg the light has stayed on. Aired up all 5 tires - yes, spare too -
and the light remains on. Manual calls for 29psi, I inflated to 30psi.
Light is still on.

Do the batteries in the tpms fail? Would a dealer charge for an opinion?
When I am near a faster connection I'll Utube search for a reset procedure,
but was wondering if the one copied below from a Toyota forum was valid.

On a Chevy it was something like the following:
1) turn the key on but don't start
2) turn the lights on and off 3 times, after the third time the vehicle horn
will beep once
3) let the air out (or add air) of the front left tire until the vehicle
horn sounds
4) go to the next tire clockwise (front right, rear right, rear left) and
adjust air pressure until the horn honks for each one
5) turn the key off and the system good


I had a similar problem ~3-4 years ago and forget what I did then.

The light should have gone off when you put air in the tires and driven it a
few miles.
The procedure is hidden in the manual.

On the lower left side of the dash is the reset button.
1. Set tire pressures.
2. Turn the ignition on, but don't start the truck.
3. If the light is on, press and hold the button until the light goes out
and then release the button.
4. Once the light is out, or if it was out already, press and hold the
button until the light blinks 3 times, then release the button.
NOW you are done!


I had one go bad in my 2007. A tire place that I bought some tires from and
provide free rotation checked it out and one was bad. They wanted about 60
or 80 dollars to replace it. Now I just let the light burn. I check the
tires anyway. Good thing in the state I live in, that does not affcet the
safety check.

Thanks for the reminder. I did do this once before. Embarrassing to forget
the button.

I wonder if resetting the button then changes the pressure setpoint to a new
value?

I found this old manual but haven't read it yet.
