Does anybody know where I plug in the scanner to read CEL on the fourth gen???

You can just plug in a jumper wire to the two wire plug located behind the stereo console. Crawl down in the driver's footwell and look behind the console and you should be able to find it. It's usually plugged into a "dummy plug" just to hold it and keep it from bouncing around.

Well, I have access to a scanner and would like to plug it in, but don't know where to plug.

I'm not even sure a scanner works on an OBD1 car. Why not just jump the connector with a small bit of wire, tell us what the CEL flashes, and we will tell you what it means. This is the process outlined in the Honda Factory Service Manual.

i got a question, what if after jumping the connector the CEL ligth doesnt flash? wouldnt even stay on?

If you have no problems, the CEL should stay solid when the service connector is jumped.

Make sure the key is in the ignition and turned to the "on" position.

if it's 96 it should be obd2, right?....the 5th gen connector is behind a cover on the passenger side of the center dash...maybe the 4th gen is there too

Yes, a 96 would be OBDII . . . but he never specified what year the vehicle was. As far as I know, all 4th gens have the CEL plug near the floor, behind the stereo.

yeah i made sure the ignition was on, ive also tried reseting it by unpluging the battery and the radio fuse. but nothing changes

With OBDII can you hook a scanner up to it and it will even tell you exactly where to look? I mean, if an engine has a problem, isn't OBDII even more specific to what the problem is?

HaPpYfAcE · 06-22-2005, 09:14 AM

it will give the general definition for the code...as it applies to the car. sometimes, it might be the right spot, but sometimes the ECU will think somethin else is the problem and say that it's maybe an O2 sensor. so if your air/fuel mixture gets a lil too lean cuz of a bad injector or somethin, it might think that an O2 sensor is goin bad cuz it's not gettin a proper reading or somethin dumb like that.

i'd say that rarely happens, but according to ol' pop, it's happened before.

i have a 96, and i've used the "OBD II Interface" plug under the cup holder in the middle of the center console when my check engine light was on a couple times.

KB798 · 06-26-2005, 10:41 PM

Just FYI, the plug is blue.
