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 are used to check circuits, sensors and actuators.

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