Update: First, I bought a scanner. The one linked above. It showed a flashing EV light and 0 dtc. Called the mfg. and they said this showed EVAC code had not reset. Dealer said I needed to drive the car "as fast as I could as far as I could". Because of an upcoming trip, by air, not driving, I really didn't have time. Looked at the info on forcing the codes and to do that in urban LA would be impossible.
When I first had the test done and failed, the smog place gave me a free retest certificate. Friday I stopped by to ask how long the cert was good for and they plugged their scanner in, said everything's cool, retested the car and it passed. I then plugged my scanner in and it still said the Evac had not reset. Thought maybe the scanner was no good so I have plugged it into four other cars and they all came up green.
End of story is that car passed smog, AirRaid has been reinstalled (WITHOUT DISCONNECTING BATTERY LOL), and all is good.
As to why scanner is doing what it's doing??
