2004 Chevy AVEO- OBDII Compliant?

[aveo owner]

Hi all, I made an attempt to check the codes with an ACTRON 9615 scanner that I had borrowed from a friend and it wouldn't connect. I tried several times and I got the same reply. I know the sticker under the hood says it is compliant, but this particular scanner wouldn't work. I know the scanner works because I used it earlier on a Chevy van that I own. Is there a different protocol on these or something? My friend insists that the scanner "should have" worked. I am seriously thinking about buying one of these scanners, but I want one that will work on all my vehicles if possible. What's the deal? Thanks.

if its an obd2 system it should work, maybe you have a dead diagnostic port?

that ^^^, or youre not doing it right.. no offense.. i trust you are doing it right.. just saying to make sure. >.< also yea, if its an OBD-2 it SHOULDDD work.. unless the scanner can convert to work on OBD-1... then it might be getting confused, although it shouldnt. but electronics these days.. @.@

Ya I don't know what to make of it either. I know I plugged it in right because I could see it going directly into the outlet.

The guy that owns the scanner said it again today, if it's OBDII then that's all there is to it.

Does anyone know what the pin outs are? For instance, there should be a power one and a ground, I would think. I have no idea what the others are. Come to think of it, it must have power because the screen comes up and says "connection failed".

He said something about it being in a flood maybe causing problems, but I don't see any evidence of it. Then again, I didn't do a car-fax on it either. I'll keep digging.

Thanks.

Chevrolet Aveo 2004 "speaks" the KWP2000 protocol (and is OBDII Compliant). Not all Scantools can deal with this. Rest of the GM family is more likely to be using the VPW protocol, or the newer CAN.

Well it was getting kind of old, to keep borrowing this guy's scan tool, so I went out and bought a Actron 9175 that was on sale at a local NAPA. And guess what,it worked. All I can say is, his must be too old to read the codes. He said it was around a 1998 vintage, so he thought. It's not a top of the line scanner, but it will read and clear the codes and has a "freeze frame" capability. I actually haven't had the time to try it on my other car, but its a 1999, so I "should" be good.
