Circuit Tests: Notes

NOTE: Before performing any diagnostic test, refer to TESTS W/CODES - INTRODUCTION article for diagnostic system functions and system diagnostic procedures.

NOTE: Models equipped with a manual transmission use an Engine Control Module (ECM). Models equipped with an automatic transmission use a Powertrain Control Module (PCM). Because the operation of these components is similar, ECM will be referred to as a PCM.

NOTE: When there is no DTC stored, MIL will stay on if the SCS service connector is connected and ignition switch is on.

When directed by testing procedure to install test equipment, see TEST EQUIPMENT in TESTS W/CODES - INTRODUCTION article.
