Not sure on the Acuras, but on the Lexus there is a reset knob on the dash: Toyota, if it doesn't reset automatically, it's a trip to the Service Center.
You did put the spare back in the trunk, right? On the Toyota's & Lexus, all 5 tires have the TPMS sensors in them and if all 5 don't report, you'll get an error light.
Check your owner's manual for any guidance.
