Computer Reset after battery change
I just bought a 2001 Oldsmobile Silhouette Premier. 160k on the Odometer. Lots of service history: trans, intake, a folder full of oil changes, etc.
When I bought it, the battery was dead. It took awhile to jump and ran well if I didn't use any electronics but wouldn't restart if I turned it off. So I replaced the battery.
I did this right before I took it to get smogged. It passed the exhaust test but when hooked up to the OBD II it failed everything but did not show a "Check Engine" or "Service Engine Soon" light. First thing the tech asked if I had changed the battery recently.
I should interject that I do have a couple lights on the cluster, ABS and Trac Off and when I start the car I get a Change Oil Soon and a Service Traction Control"
He said the computer needed a little while to reset and I should drive it around for about 30 to 50 miles and come back. I hit the road and put about 45 miles on it and returned. He said that most of the systems had reset but it was still reading an E-vap and another code (I don't remember which one) but still no CE or SES light on the cluster which was a good sign.
It was late so I got on the freeway and put another 50 miles on it with the intent of taking back in the morning. Still no Check Engine or Service Engine lights. I got called into work so I had my wife take it back to the smog shop. She called to say it was still throwing codes. We probably put over 100 miles on the van in the last two days.
How long does it take for this computer to reset after a battery change?

My wife had the day off so she put another 120 miles on the van. Still no CE or SES light. She took it back to the smog place, still throwing codes. The tech said we should try a bunch of cold starts. So start the van, run it until it gets up to temp and park, rinse and repeat.
Does this sound right to anybody?

It doesn't come on when i start up. I'm taking it back to the smog guy today. When my wife took it there on Wednesday, the tech said that we were waiting for one last system to reset, something about a system that controls the air intake on cold starts. I guess it has to cycle through a few cold starts before it resets. Since we have just been driving it without many cold starts, that system hadn't reset yet. We'll see today.
