QUICK TEST and SYSTEM TESTS are diagnostic formats used to test and service EEC-V system. QUICK TEST allows technician to identify problems and retrieve diagnostic trouble codes. SYSTEM TESTS are used to check circuits, sensors and actuators.

Before starting any SYSTEM TEST, follow all steps under QUICK TEST  to determine appropriate system test to perform. If vehicle passes QUICK TEST and no driveability symptoms or intermittent faults exist, EEC-V system is okay.
