Correct way to reset ECM

Thanks, Mike. That is exactly what I found is true. I tried to reset mine several times after the ECM was replaced and did the "battery disconnect" thing the first two times. but failed to let the cooling fans cycle. I then read an article (I think Stu Oltman wrote) that said exactly what you posted. It worked perfectly.

Hey, Bill Anzik, ride through that section of road work near the Three forks junction north of Townsend at 20 MPH......that will turn your fans on :shock:
