Diagnostic Tests: Notes

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

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

NOTE: For wire color identification at PCM terminals, see PIN VOLTAGE CHARTS - 2.4L article.

Using scan tool, Malfunction Indicator Light (MIL) or voltmeter, display and record trouble codes. See ENTERING ON-BOARD DIAGNOSTICS under SELF-DIAGNOSTIC SYSTEM. If no codes are displayed, see TESTS W/O CODES - 2.4L article.

Clear trouble codes after each repair. See CLEARING CODES under SELF-DIAGNOSTIC SYSTEM. Recheck for codes to confirm repair. See ENTERING ON-BOARD DIAGNOSTICS under SELF-DIAGNOSTIC SYSTEM.
