Diagnostic Formats

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

Before starting any CIRCUIT TEST, follow all steps under QUICK TEST  to find correct CIRCUIT TEST. If vehicle passes QUICK TEST and no driveability symptoms or intermittent faults exist, EEC-V system is okay.
