    Just changed from 2015 OEM 20 to 2015 OEM 18 inch tire/wheels new takeoffs. My 20 inch from Toyota ran 49 psi per B pillar label. The new 18 inch run 33 psi. Discount Tire got the the truck to recognize the new TPMS. Problem is the trucks ECU is set at 49 psi. I get the low pressure icon at 33. Aired all tires up to 45 and the icon goes away. Need to have the ECU triggering pressure reset and suspect the Toyota dealer is my only recourse. Any ideas or suggestions.
    Thanks for any help or suggestions.

    Figured it out. Reset button on lower dash did the trick. Misunderstood its function.
