"vehicle not responding"
Hooked up Auto-X-Ray 6000 to DLC link and STI. Works perfectly on 11 out of 12 various vehicles owned by my sons and I. Ran through test on '93 w/5.0 man trans to correct idle running up to 1500 and back down to 1000 rpm. The scan diagnostic device reads "Scan Failed- Vehicle not responding". Checked with a couple of shops and got different answers. One stated "That year doesn't have diagnostic capabilities". Left there amused. Why would the truck have a DLC and STI connector for scanning if it was not capable? Granted it is only OBD 1 but it should read something. I think the link is disrupted between DLC and PCM. Or the diagnostic portion of the PCM is shot. Any input greatly appreciated. Thanks in advance c.j.

if that works, the scanner isnt compatible, if not, you got a wire issue or fuse..or something

If the manual method works I'd say operator error w/ your reader is likely. If your ECU is toast & it's running, it would be in failsafe mode, which would be pretty crappy & about 9-10 MPG max w/ a flat timing curve.
It is common for the wire connector contacts of the ECU test connector to work their way out of the back of the connector. Causing a non connection when the reader is plugged in.

Thanks for the replies. I'll check into your suggestions. I don't believe it's operator Error,. I've scanned way to many vehicles besides mine and never had a gitch. This diagnostic tool is very easy to use and pretty much plug and play. Then again I've slept since then........c.j.
