<FONT face="Courier New, Courier, mono" size=2>I'm trying to pass the vehicle test with my 3.8L 1999 Mustang, 5speed.for the county here in TN. The testing center says my computer(ECM)is not ready to be tested. I even went to another test place, same thing. Took to the dealership, they charged $47.00, and said, ok, drive it for about a week and it should be ready. No, it wasn't, and then went back to dealer, they gave me a drive cycle to do, did it, and still, computer tested not ready.</FONT></P>


<FONT face="Courier New" size=1><FONT size=2>After another final attempt at the dealer, they gave me</FONT> <FONT size=2>S</FONT></FONT><FONT size=2>ome bull about a possible "intermittent problem", right! They wanted to charge me $250.00 to inspect the wiring harness, then if it's not itsomehow test the computer, and charge more money and still not know what the problem is. Please tell me theres someone out there that knows what this problem may be. Surely I'm not the only one to have this problem. Any help would be great.</FONT></FONT></P>

well i dont know how to solve your problem, but for better responses edit that into a bigger font

 

For starters, that drive cycle your supposed to do is nearly impossible to do unless your on a closed circle track or something, I mean the speed and throttle positions your supposed to keep the car at for those times without exceeding them or braking etc. Its really not practical for anyone to do. </P>


Could you elaborate on "not ready to be tested". I mean, you either pass or fail an emissions test. The drive cycle you refer to is to get the computer "broke in" after a MAJOR computer repair, like a new CPU for example, not to fix a problem. I'm no Ford tech, but I did stay at a Holiday Inn last night... no in actuality I was in an OBDII seminar a few years ago (1999) shortly after the system came out. </P>


Surely though, your the only person I've heard of with that problem. </P>

 

<FONT face="Courier New, Courier, mono" size=3>Thankyou for the reply, when the car was tested at the test center, theyconnected their computer to the cars OBDII plugin, I watched the screen as well when after one minute or so it said"System monitors not ready".:CATALYST</FONT></P>

<FONT face="Courier New" size=3>THAT WAS BASICLLY WHAT PRINTEDon my sheet they gave me, and of course it is considered "test failed" becauseTHOSE SYSTEMS AREN'T READY TO BE READ BT THEIR COMPUTER. AT LEAST THATS HOW THEY EXPLAINED IT TO ME. IT IS OBVIOUS ALSO THAT THOSE GIYS AT THE TEST VENTER ARN'T WHIZZES ABOUT THIS STUFF EITHER. BUT THEIR ADVICEWAS TO GO TO THE DEALER FOR THIS DRIVE CYLCLE, WHICH I AGREE, IS ABOUT IMPOSSIBLE TO DO. BUT THE QUOTATION I GAVE ABOVE AND THE LIST ARE EXACTLY WHAT THE FAILED TEST PAPER SAYS EACH TIME. WITHOUT THEM ABLE TO TEST THE CARS COMPUTERIT WON'T PASS THEREFORE, NO NEW REGISTRATION.</FONT></P>


<FONT face="Courier New" size=3>AND THERES THE RUN AROUND I BELIEVE I'M GETTING FROM THE DEALER. IS IT POSSIBLE TO RESET THEECMSO IT CAN BE READ BY THEIR TEST COMPUTER?I MYSELF AM NOT A WHIZZ AT THIS EITHER, I DO APPRECIATE YOUR TIME IN ANSWERING</FONT></P>


<FONT face="Courier New" size=3>THANKS</FONT></P>

 

Why the hell are they hooking anything up to your car besides the F'in sniffer ??????? I don't get it..

 

<FONT face="Courier New, Courier, mono" size=3>IN THE STATE OF TENNESSEE THEY STARTED REQUIRING TESTING OF ALL CARS THAT HAVE OBDII, TO ENSURE I GUESS THAT YOUR CAR IS MONITORING EMISSIONS PROPERLY. </FONT></P>

 

Sounds like your car isn't going into closed loop. Those are all emissions systems that do not function until your car goes into closed loop. Closed loop occurs whenever your car warms up to normal operating temperatures. You didn't put a 160* thermostate in did you? Does your gauge read in the low normal range?

 

<FONT face="Courier New, Courier, mono" size=3>no, never replaced anything major except for sparkplugs, oil changes etc...</FONT></P>


<FONT face="Courier New, Courier, mono" size=3>the gauge is always 1/4 up never past 1/2 way. could it be the thermostat not working properly?</FONT></P>
