Diagnostic Formats

WARNING: This page is about a different variant/trim than selected.

QUICK TEST and SYSTEM TESTS are diagnostic formats used to test and service EEC-V system. QUICK TEST allows technician to identify concerns and retrieve DTCs. SYSTEM TESTS check circuits and solenoids of transaxle system.

Before starting any SYSTEM TEST, follow all steps in QUICK TEST under DIAGNOSIS & TESTING to find correct SYSTEM TEST. If vehicle passes QUICK TEST and no driveability symptoms or intermittent faults exist, EEC-V system is okay. If EEC-V system is okay, attempt diagnosis by symptom. See SYMPTOM DIAGNOSIS under TROUBLE SHOOTING in FORD AX4S OVERHAUL article.
