It is time for my smog test. I have a code reader showing 'incomplete' on a lot of items formonths now. I brought it to smog station hoping he could clear it or run this procedure on the roller device for smog test, but he won't do it:

Volvo Technical Service Bulletin #SB 2-23-0056

Start with the vehicle cool, below 122 degrees F.
Turn off the air conditioning.
Select a location where the driving can be done without violating traffic laws and you can stop safely at the side of the road.

1. Start the engine and accelerate to approximately 1500-2000 rpm.
2. Drive for 6 minutes at 1500-2000 rpm.
3. Stop the vehicle and remain at idle in drive for 70 seconds.
4. Accelerate to at least 45mph and drive for 5 minutes at 1800-2200 rpm.
5. Stop the vehicle and remain at idle in drive for 60 seconds.
6. Accelerate to at least 45 mph and drive for 4 minutes at 1800-2200 rpm.
7. Stop the vehicle and remain at idle in drive for 60 seconds.
8. Park the vehicle and turn off the engine.

This procedure must be performed TWICE from a cold start to set the readiness codes.

I am thinking of raising my car and press the gas pedal to the desired RPMs. Only difference is it won't be running at 45mph. I wonder if the readiness cycle looks at MPH speed too ? Has anyone tried just lifting the car ? What would the Volvo dealers be doing to clear it and charge $150-375 ? This must be the trick !!! ???

Other thing is: Is it true that the 1996-1998 Volvo V70/S70/C70's could get exempted for incomplete ODBII readiness because of this issue ? Anyone there pass the test in California with Smog Station exempting your car because of this ???
