When the power is disconnected the computer is reset, you need to run what is called a drive time protocol to bring everything back into specs. On your vehicle I recommend that you disconnect a battery cable, turn on the headlight switch, wait at least 30 seconds, turn off the headlight switch, then reconnect the battery, start the engine and drive it for at least 20 minutes, watch for a check engine light, if no light comes on then the system should be ready for testing, if you get a check engine light that will have to be fixed before going any further. Remember the vehicle must be running at operational temps for at least 20 minutes before emission testing. If it fails testing again then you will have to take it too a shop that can do live data testing to find out what is happening.

Sometimes it takes longer than 20 minutes so just be patient with it. All the pollution control crap has to go through its drive cycles to be up to snuff for the emissions testing.
