You should have a listing of reasons why the alarm was triggered,if you used tech 2. Check that out too. With the ultra Sonics. Check for damp between the headlining and roof by the roof lamps. There is a big black multi plug above the lights. Check there for signs of water / condensation. That plug has a smaller blue block connector in it this is your ultra Sonics. Don't worry about the second code, we get that type of code all the time. Only worry if it keeps coming back.
