WARNING: This page is about a different variant/trim than selected.
QUICK TEST and SYSTEM TESTS are diagnostic formats used to test and service the diesel EEC-V system. QUICK TEST allows technician to identify concerns and retrieve DTCs. System tests 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 functioning properly at this time.
