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.

For any test that requires probing PCM or a component harness connectors, use Connector Test Adapter Kit (J- 35616-A). Using this kit prevents damage to the harness or component terminals.

NOTE: Before clearing DTCs, perform powertrain diagnostic system check. See DIAGNOSTIC SYSTEM CHECK - ENGINE CONTROLS  under SELF-DIAGNOSTIC SYSTEM. Record FREEZE FRAME and FAILURE RECORDS for reference during testing. Data will be erased when DTCs are cleared. If PCM is replaced, NEW PCM must be programmed using special manufacturer's equipment.
