UNABLE TO SCAN ENGINE CODES - ZR-1 Net Registry Forums

GOFAST · 07-17-2012

I have a '95 with 9000 miles. The "Service Engine Soon" light comes on intermittantly, stays on for a few seconds, and then goes out. I have tried to capture the stored codes using a scanner but the scanner has been unable to connect/communicate with the ECM.

Two different scanners have been unable to link/communicate with the host but both work fine on my other car. My '95 has a OCB2 connector. Any idea as to why the scanners can't connect with the ECM?

Thanks.
