When was the last time the oil was changed? My sister's minivan has that message displayed every 3 months. She takes it into the dealer and has the oil changed,which fixes it. There might be a faulty sensor sending a signal to the computer, causing the Service Engine Soon light Your Secondary Air Pump may be bad. Water gets into the pump and causes it to short out. If you get this replaced, make sure you get the breather vent extension kit installed or you'll have the same problem again in few months.
Maybe you should service the engine soon. :P

How do you reset check engine light for the 2009 Chevy trail blazer?
unhook battery or scan tool will do it
I had my 200 blazer scanned an was told it was a bad fuel tank cap. I replaced it and the light is still on.
There is a problem with the emmission system are transmission and the computer turns the engine light on to let you know there's a problem. Have engine scanned with a OBDII engine scanner.
Discconect the negative cable from the battery for a few minutes and that should do the trick
