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 Control Module (ETACM) wiring harness connector determines whether it's receiving and transmitting proper signals. Locate ETACM. See ELECTRICAL COMPONENT LOCATIONS , and check for voltage or resistance as indicated with connector connected (backprobe connector). SeeFig 1 . See ELECTRONIC TIME & ALARM ECM CONNECTOR PIN VOLTAGE CHART If value is not as specified, repair or replace as necessary.
