Found rest of test
ZEDN Ign on, test for between ground wire and signal wire is 4.8-5.2 volts. If less check the wiring or run new wire and connectors. If you think the wiring is ok, Replace the ecu. That's all to this part of the test. Without a good scanner tool this is not an easy curcuit to fix. Need a fluke 88 ohm meter for mid/ max readings in milli seconds. You have your answer. Good luck with car. Rick L.
