OBDII Readiness and Drive Cycle
I have an error code that needs to be reset and I know when it's reset, all tests need to return to a readiness state. I know how to reset the check engine light. but does anyone know the Drive Cycle needed to have all the test report with a success so it will be Ready for the emissions test?
I know people say just drive around for 2 weeks, but I've seen what needs to be done to have the car perform all the tests in just a few days. GMs can be performed in under 15 minutes.
http://obdii.com/ has the Driving Cycle for GM and Ford vehicles but doesn't list Lexus/Toyota.
I guess it's probably listed in a service manual.. anyone have one?
thanks

I had to do it for mine. The tech told me about 15 - 20 minutes driving (which is about what it takes me to get to the Lexus dealer) and mine passed / read just fine.

So there's no specific start-up, idling, etc procedure involved? Just simply drive for 15-20 minutes?

Nope. Just pull the battery cable (or appropriate ECU fuse) to reset the CEL. Then drive around normally for 15 - 20 mins. This assumes of course that whatever trips your CEL in the first place only does it under certain conditions (like mine does) and it doesn't pop back on during those 15 - 20 minutes.

if your scanner can show monitors, you can tell if they are up.the monitors have to be up to pass state inspection.usually a good 10 miles will reset enough monitors to pass state.

This is specific instructions for Lexus and Toyota drive cycles to reset readiness monitors.

Not Ready
Newer than 2002 vehicles 15-20 minutes still?
I just went through a huge fiasco about my car not being "ready" at the emissions testing center. The battery has been dying (never drive it) and I recently replaced bank2 sensor1, so I wasn't quite sure I'd pass. I drove 15 miles (25+ minutes) to the testing location, waited, and was told my car wasn't "ready".
It would be nice to know what the requirements are for this readiness state so I don't have to "drive up to 400 miles for the computer to show the ready state" (tester guy here in Colorado)...
Ended up driving 30+ miles (hour and a half through city and highway), taking it to a service center where the guy plugged in his SnapOn scanner that showed "everything was good". I went back to the emissions place and it passed, but I spent half my day getting the test done and was angry not knowing the state of "readyness" of the dang thing.
Why would it take "up to 400 miles of driving" for the cars computer to show "ready"?

I like that drive.... 400 miles ......what BS. That could be a coupe tanks of fuel for some vehicles in a city LOL. Wonder how much emissions you'd spew out just to prove your car is not spewing too much. I am so thankful our area does not have emissions testing and even in the places in the state that do I think its still only tail pipe emission reader at idle and you can not have a lit cel.

Yep - complete BS. Old smoking 80's Ford trucks coming out of there that "passed"?... Hmmmmm ... The guy testing told me they test hybrids and full electrics... WTF? SERIOUSLY COLORADO?!?!?! Just another way to legally rip people off.
