I have a 96 Eclipse RS, and I went to go get it inspected( I live in Texas) and some of the readings say "Incomplete" and asked if i recently disconnected the battery, etc, and i told them i havent for a month,So, we drove it for 100 miles like the recommended, and they still say Incomplete, and my car cant pass inspection with out it. I believe something is wrong with the ECU, and im curious if any of you have any ideas of what might be wrong and/or what I can do. I have a OBD logger, so i can easily find out if they ever become complete or not. Any help would be nice, i want to spend as little of money as possible.

Edit: Ok, I must of been tired last night or something, and now remember and know that the ECU's have these problems, and found on the fourms that i can take it to the dealer to have it reset then go straight to inspection. But I am curious, one guy in another fourm said this

"Take it back up there and tell them to read the notice about the hyundai and mitsubishi OBDIIs not reading correctly. Usually the machines automatically switch over to ASM or TSI if they're ESP machines..."

What is he talking about and do I not have to go over to a dealer to have it fixed?
 
Which items show incomplete?

The ecu has some weird rules about component self checks.

It may require a few drive cycles to complete all diagnostic self checks.

There's some really strange paramenters for the evap/purge system. I'm not very familiar with 2g requirements, but a lot of obdII systems require a coastdown from highway speed without touching the brake in order to actuate/test evap and purge.

Please post incomplete items, and we'll see if we can come up with a way to get the systems to run their diagnostic routine.

Also, some dataloggers *may* lockout the diagnostic self check routine in the ecu's operation, so it might behoove you to turn the datalogger offf and run a drive cycle or two.

Good luck, and let us know. I'm a little curious myself.
 
The ones that show incomplete are:
Catalyst
Evaporative System
Oxygen Heater
Oxygen Sensor
EGR System

Like I said, i was able to get 3 of those to show complete, but then they disappeared again after i started the car. And also, I found a thread on here that said that I would have to take it down to the Mit Dealer and have it reset. http://dsmtuners.com/forums/showthread.php?t=213957&highlight=obd

Thats the thread, and im pretty sure im going to have to take it down to the dealer, but if anybody knows what that one guy meant before i go down to the dealer. But ya, those are the one's that show incomplete, all the non-continuous monitor's.
