Default Computer dic codes missing failed Illinois air polution test

Took the car in after 5 year passed air pollution tests,where they stick the wand in and the gas cap test.

now they insert a connect to the dashboard, and even though my check lite is off, they say the computer readings are missing on my computer......I t works fine, all dic readings show H, and its fine and working as too settings, milage, oil reading, etc.

She says maybe the battery was disconnected from the
car, so settings werent, there.

Should i reset the computer drive 40 miles and will the
settings record, or do i have a defective computer.

Car works, drives fine...dont want to dealer destroy.

I am guessing that some of the readyness tests have not
completed. As suggested it the battery was disconnected
codes would have been reset. Normal driving and time should
allow the tests to complete. Then you should be ok.

"computer readings are missing on my computer"?
She(?) didn't say what the hell computer readings she was talking about? It may just be that their connector or cable is having problems and their test equipment cannot establish communications with your computer(PCM).
Clear all those H codes, put a few miles on her and check to see if any have re-occured. If any do, see if any are carrying a "U" prefix and see which system is involved. "U" codes have to do with communication on the serial data line (computer and sensors use it to talk to each other). It doesn't always mean any real problems exist though, especially if you don't have any failure sypmtoms in a system. For example, U1016, U1064 and U1096. These only mean a sporadic or temporary loss of comm in the RFA system and unless there is also an accompanying problem, these can be ignored.
Maybe the putz at the test location just couldn't figure out he's got a damaged cable or connector. They do after all use them many times daily.
Another suggestion would be to go to another test location to see if they experience the same thing. HTH.

Default codes

You know what, the idiots had a problem 25 min with a car ahead of me: I blew up on them, and they probably took it out, by faking a bad test.
Illinois is in such bad shape, I think your right.
Standard, government inept employees.

If you reset any DIC codes that throw the check engin light this will also bring back a sensor not ready falt on the OBDII smog test. Check Bill Curlee's post for the OBDII self diagnostic test in this link.

Nope, they're not gov't. employees. They are contract employees hired by a company that was hired by the State of Illinois to operate their testing stations. Most of these people look like they received their G.E.D. degrees from Joliet State Correctional Facility. Inept---to say the least.

I think you found your problem.

I'm glad that Ohio finally saw the light and killed this program (at least temporarily). The contract workers that I came into contact w/ here weren't of the highest caliber.

The I/M monitors are reset if any codes are cleared. I will not take 2500 miles to set them, maybe 50 or so. Prior to the 2001 model year you could have 2 I/M monitors "NOT READY" and pass in Illinois, after that 1. You can read the readiness monitors with a simple OBD reader like an Actron, I don't think the DIC shows rediness state. I just use my laptop OBD scanner anyway to check things and rarely use the DIC except to see and historical codes.

I thought I read that the codes cycled thru every 40 starts. If you disconnect the battery then you'll need 40 trouble free starts. Have a tuner scan your computer and see what's up. The PO may have done something to it you're unaware of.

IL is a real s**t hole when it comes to government. A past Gov is close to spending time in jail as the jury is in delberation as we speak and the present Gov. is also under investigation. The Cook co. board president would be next if he hadn't just had a stroke.

Too bad we can't just plug a bogus comp in for the OBDMII for testing purposes. Hey now there's an idea. Anyone know how to program something to trick the Green police?
