"Not Ready" for OBD Emission test...? Topic is solved

[abscate]

The ones which are available and not complete are the trouble spots; You won't pass until those go,ready.

The P80 platforms are one of the early OBDII systems that may take some time to collect enough data to show "ready" for testing. Volvo's are not alone in this tendency, and some states maintain flexibility in testing protocols and readiness monitors. Maryland does not appear to be one of them.

Generally, the following driving cycle performed twice is sufficient to reset the monitors:

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.

Alternatively:

1.) Accelerate 0-50 MPH within 30 seconds
2.) Maintain 45-50 MPH for 20 minutes without using cruise control
3.) Park car turn off A/C idle for 5 minutes
4.) Accelerate 0-50 MPH within 30 seconds
5.) Maintain 45-50 MPH for 20 minutes without using cruise control
6.) Shut off car and allow to cool for 30 minutes before repeating cycle ( in some cases the car requires two cycles)

An OBDII reader is a must-have tool for any DIY diagnosis and repair, but unless there is a check-engine light, reading codes isn't your problem here, it's a lack of data from a recent reset.

This worked! I did it today, and one time through the first version did everything I needed.

That driving cycle sounds like my drive to work :p

When was the last time you either cleared codes or disconnected the battery? Each time you do this you have to drive cycle 50-100 miles to reset monitors

I haven't cleared codes or disconnected the battery since I purchased the car in the beginning of October.

I do have an issue that blows a fuse, and took me a few fuses to find which one.

I've put over 1k on the odometer since the most recent time the fuse blew.

If it's the same fuse as the ECM it will reset it of course.

On the drive cycle it's important to start with a cold engine, AC off, and fuel tank between 1/4 and 3/4 full.

You need to do the "flywheel adaption procedure" look it up. Before the driving cycle. It can be hard to do, So my state has an exception for my 98. No ready tests need to to completed (PA). I can reset the codes and go get tested and pass everytime. The inspection stations can't believe it, when it happens (passes). I had to tell them to input 2.3l instead of the 2.4l it is (the first time, now PA remembers), (told to me by the local volvo dealer service guy).

thanks for the info, the driving cycle worked for me without performing the flywheel adaption.

Glad it worked for you, too. I pulled some of that out of a factory manual a friend had. Saved me a few times after doing some last minute "un-mods" to pass visual or repairs to clear a CEL for the test when tags are due.

Took the test this morning and passed!

Thanks everyone who posted.
