Circuit Testing: Notes
NOTE:
Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. Voltage readings may vary slightly due to battery condition or charging rate.
Checking pin voltages/resistances at the electronic time and alarm ECM wiring harness connector determines whether it's receiving and transmitting proper signals. Locate electronic time and alarm ECM and check for voltage or resistance with connector connected (backprobe connector) as indicated. SeeFig 1 . If value is not as specified, repair as necessary.
