Going NUTS!! No data from ECM to OTC 2000???HELP!
I am about to loose it!! Been trying to track down why I dont get any data to my OTC 2000 Monitor. But I get a code 12 when I jumper to ground? I have also checked the ECM serial data output to terminals E and M at the ALDL. It reads 5.0V. Any body have any ideas or thoughts? Camaro 91 5.7TPI ECM is 7730. Thanks!!!!!
