I had my check engine light go on the other day, and i fixed the problem.  But now when I check for trouble codes it shows that their is still one incomplete test, and I'm due for inspection, so....

Is there a way to find out what the incomplete test is?

If your car has an electronic management, and the techs who inspected it did not tell said management that EVERY test was made... go to them, open their heads with an hatchet, spit inside, then close the opening with barbed wire... this finished, make then them put the electronics in your car in "non-annoying" mode, and then, for last, next time you have to go for an inspection, choose someone who knows how to do their work instead.

Hmm.. could be the crash test. I've had two cars that had errant warning lights because of a bad "chip". (onboard computer chip)

I suggest just run it through the inspection and see what they tell you. Both of my cars with bad chips were Pontiac Firebird and Chevy Cavalier. It turned out there was thousands of aftermarket chips from Korea with software glitches. They worked fine for a while and then would start giving false readings.(GM products) It could also be that rather cheap yellow thing your holding! No offence intended!

How do you know that "INC" means incomplete test. The paperwork, codes and instructions don't mention that report with my reader?

You have miss understood me. How do you know that what is in the display means "incomplete test"

You could try disconnecting the battery for 5 minutes. In many models that will reset the onboard chip. Then you would run another test and see what comes up.

15 mins on a Renault and it then loses the stereo code so make sure you know it before you play!

Wow!!!

This doesn't happen on a FIAT, and I know it because I own one. So you're telling us the French managed to get one up on us on the effort in worsening their cars' management? Scandalous!

If I had to guess, I'd say that if it is an incomplete test, it likely is a readiness monitor that the car always runs. An example would be a catalytic converter test, or an oxygen sensor test; these are pretty much all emission related tests. To run the test, simply drive the vehicle. Some tests like the evap system test can even take several drive cycles, so dont just assume something is wrong. If something is wrong, your check engine light will once again come on.

And to answer this...
