Can't read SES codes - ZR-1 Net Registry Forums

MuRCieLaGo · 03-31-2016

Hi,

'91 ZR-1

Just finished installing headers and Marc Haibeck's chip. I didn't connect the exhaust system to the headers yet.

When I started the car, I forgot to plug the connecter under the ECM. So it ran pretty rough. Now everything is plugged, even the small vacuum line going under the ECM.

I got a SES light (and a SRC). I managed to read the SRC light with Dynomite's Code Reader (13,14 then I stopped at 14 because I'm pretty sure it will show all codes) but I am unable to read SES codes, even with the paper clip method. It worked fine before installing the headers.

However, when I removed the chip to send to Marc Haibeck, i accidentally unpinned a wire going to one of the ECM connectors, as you can see on the picture.

Should I tow my car to the nearest electrical shop, to have that wire pinned back? Could it be the solution to my issues? Black and white wire.

Thanks guys!
