I have a 96 civic HX , the vehicle has no codes but for some reason the monitors are acting goofy. I drove it 100 miles then rechecked the monitors, It showed that I had 6 out of 7 reading. I took it to the smog shop that same day to get passed the smog. Once I got to the smog shop I turned off the car as there was 2 other cars before me. When it was my turn I pulled up to the bay and the tech said to turn off the car. I did that. Then he hooks up the OBD11 from the smog machine and tells me that there are only 3 out of the 7 monitors reading !!! Ok, now I'm confussed, I've never seen it where the monitors show reading 6 of 7 and then going backwards to only be reading 3 of 7 ! Now like I said, it runs good has no codes set but yet for some unknow reason I lost 3 monitors between my house and the smog shop ! Anyone ever have this happen to them ??? Please help if you can, thx in advance ![/QUOTE]

It only sets readiness monitors. To re-set any you have to re-set them all (ECM/PCM re-set). I suspect one of you was reading it wrong. I hope you went to a no-pass no-pay place.

Thanks for the fast reply lazlong. Well I have 2 scanners, MT2500 snap on, oldie but goodie, lol. I also have another that I use just to do quick code checks with. I'm 100% sure that I had 6 out of 7 reading at the time I checked it. But like i said, I've never seen monitors not read after seeing them reading. To the best of my knowlegde you can only reset all the monitors at the same time. I don't think there's any tool out there that will let you pick and choose what monitors you want to reset or not reset.

Yeah, inexperienced inspector more than likely. Take it somewhere else.
