Self-Diagnostic System

WARNING: This page is about a different car, the 2002 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before beginning self-diagnostics, perform basic checks. See TROUBLE SHOOTING .

Connect New Generation Star (NGS) tester to Data Link Connector (DLC), located below instrument panel. Using NGS tester, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in MODULE COMMUNICATIONS NETWORK - F150 PICKUP article. If NGS tester displays CKT914, CKT915 or CKT70=ALL ECUS NO RESP/NOT EQUIP, diagnose module communication problem. See MODULE COMMUNICATIONS NETWORK - F150 PICKUP article. If NGS tester displays NO RESP/NOT EQUIP for Generic Electronic Module (GEM), perform TEST A: NO COMMUNICATION WITH GENERIC ELECTRONIC MODULE under SYSTEM TESTS.

If NGS tester displays SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Perform self-test diagnostics for GEM using NGS tester. If GEM DTCs are retrieved, see GENERIC ELECTRONIC MODULE DIAGNOSTIC TROUBLE CODE INDEX table to continue diagnosis. If no DTCs were retrieved, repair system by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
