#12 of 17 Emissions Testing OBDII System not ready by abbyscharm

Dec 17, 2009 (8:13 pm)

I own a 98 Saturn SL2 series. When I take it to emissions it keeps coming up OBDll systems not ready to test. So if that part is not ready they will not even follow thru with the test. Until the computer has run through a complete cycle. The problem I am having is I do not know how to run it through a complete cycle. I was told to run it at least 200 miles. I did so. It still came out the same problem at emissions.

I bought the el cheapo version of the Equus/Innova reader on Amazon.com, maybe $57?. It would not read codes from my 2002 Forester until I did something, but I cannot remember what the something was; maybe it was as simple as starting the engine. If that is the case, since the car is in the garage, that would require the door to be open.
 
I used it to fix a knock sensor. Paid for itself right there.
 
It has NO memory, NO batteries, no real time, it takes power from the vehicle. Just bring a pencil to write down the numbers.
 
What the heck? That is NOT my car in the preview picture!!! Gone when I post though.

I found on another web sight the possible answer. If you guys don't think this will work please let me know.
It states. What is the obd-ll drive cycle for a 99 Saturn SL2.
 
A: - 1-8 cold start, accelerate, hold steady speed, decelerate, Accelerate, Hold steady Speed, and Decelerate. With more detailed information on each 8 steps.
 
Thank you again,
I will try this. If you have any other info please let me know. Thank you, Abby

Usually, you plug in the reader before turning on the car. Then, once plugged in, turn the key to the 'on' position, but do not start the engine. At that point, the reader should come on and you can press the "link" button to download the codes.
 
Don't worry about the preview picture - it seems to be some sort of non-executed functionality that has been there since the forum went to the current format. On CarSpace member pages, posts include a thumbnail (and include the correct one!), but that feature was never enabled on the forum.
