Emmisions test required

[Doubeleive]

Which of the emissions show as not ready?

apparently the dealer must have had the battery disconnected when I had it there last week because now it only shows evap and everything else has set, weird

In California you can pass with the evap readiness monitor not ready as long as the rest are complete and the check engine light is not on.

If you Google "gm drive cycle" you can set the monitors in about 10 miles from a cold start but you need a road with light traffic.

ya you know what's weird is that truck has all kinds of "not ready" emission's with 26k on it I have driven it a 1000 miles since I bought it and haven't disconnected the battery so I don't know what's up with that but it still doesn't have to have a smog inspection for 50 months.

it should all be ready with in 200-400 miles except for the EVAP.. even after 1,000 miles not yet
