CAUTION: Perform all resistance and voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm impedance, unless stated otherwise in test procedures. Ensure ignition switch is in OFF position when performing resistance tests, unless stated otherwise in test procedures.
NOTE: Not all Diagnostic Trouble Codes (DTC) are applicable to all models. Ensure specified DTC test procedure applies to model being repaired.
