Test Equipment

All voltage tests should be performed with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless specifically stated differently in testing procedure.

When directed by testing to install Engine Control Module (ECM) test harness, turn ignition off. Connect ECM Test Harness (07LAJ-PT3010A) between ECM and ECM connector. See Fig 1 . Follow testing directions. For test harness terminal identification, see CONNECTOR IDENTIFICATION  .
