Diagnostic Formats

QUICK TEST, CIRCUIT TESTS and PINPOINT TESTS are diagnostic formats used to test and service EEC-V system. QUICK TEST allows technician to identify problems and retrieve Diagnostic Trouble Codes (DTCs). CIRCUIT and PINPOINT TESTS check circuits, sensors and actuators.

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