Diagnostic Tests: Notes

CAUTION: Ensure ignition switch is in OFF position when performing resistance tests.

NOTE: Perform all resistance and voltage tests with a Digital Volt-Ohmmeter (DVOM) with minimum 10-megohm impedance, unless stated otherwise in test procedures.

Clear fault codes after each repair. See CLEARING CODES. Recheck for codes to verify repair. See RETRIEVING CODES WITH VOLTMETER or RETRIEVING CODES WITH SCAN TESTER.
