Using Scan Tool
For preliminary testing, see TROUBLE SHOOTING . If problem is not found, connect NGS tester to Data Link Connector (DLC). DLC is located below center of instrument panel, right of steering column. 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, repair module communications concern. See MODULE COMMUNICATIONS NETWORK - F150 PICKUP article. If NGS tester displays NO RESP/NOT EQUIP for Alternative Fuel Control Module (AFCM), perform TEST A: NO COMMUNICATION WITH ALTERNATIVE FUEL CONTROL MODULE under SYSTEM TESTS. If NGS tester displays NO RESP/NOT EQUIP for Hybrid Electronic Cluster (HEC), perform TEST A under SYSTEM TESTS in ANALOG INSTRUMENT PANELS - F150 PICKUP - GASOLINE article.
If NGS tester displays SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Perform instrument cluster and AFCM self-test. See MODULE COMMUNICATIONS NETWORK - F150 PICKUP . If DTCs related to concern are retrieved, perform appropriate test. See ANALOG INSTRUMENT PANELS - F150 PICKUP . If DTCs not related to concern are retrieved, perform diagnostics on HEC. See ANALOG INSTRUMENT PANELS - F150 PICKUP . If no DTCs are retrieved, repair by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
