Diagnostic Tests: Notes

WARNING: This page is about a different car, the 2002 Subaru Impreza. However, it is still accessible from the selected car via links, so may be relevant.

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.
