Diagnostic Tests: Notes

CAUTION: Perform all resistance and voltage tests with a Digital Volt-ohmmeter (DVOM) with minimum 10-megohm impedance, unless stated otherwise in test procedures. Ensure ignition switch is in OFF position when performing resistance tests.

NOTE: Subaru Select Monitor (SSM) or OBD-II generic scan tool must be used to perform diagnostic tests. Values and procedures given in tests are based on the use of SSM scan tool. Follow scan tool manufacturer's instructions. After repair or replacement of faulty parts, clear memory and perform verification of repair. See VERIFICATION PROCEDURE and DRIVE CYCLES . For ECM terminal and electrical harness connector identification, see Figure. For identification of circuits, terminals and wire colors referenced in the following testing, see ENGINE PERFORMANCE in appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL.
