Self-Diagnostic System: Self-Diagnostics
WARNING: This page is about a different car, the 1998 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The remote keyless entry system utilizes a self-diagnostic system which may store a Diagnostic Trouble Code (DTC) if a problem exists in the system. DTCs may be retrieved using NGS tester and Data Link Connector (DLC) for diagnosis of system. Before performing any testing, a preliminary procedure should be performed. See PRELIMINARY PROCEDURE.
