1997 Ford Explorer 4D Utility, 4.0 E, 4WDSECTION Description & Operation
WARNING: This page is about a different car, the 1997 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The module communications network provides the capability for module-to-module communication by sharing inputs and outputs instead of each component having an input and output wired directly to each module. A BUS which consists of a pair of twisted wires is used to transfer information between modules. The BUS consists of a (+) circuit No. 914 and a (-) circuit No. 915. The BUS is routed only to the Powertrain Control Module (PCM). For module locations, see COMPONENT LOCATIONS TABLE. In the event that a system failure exists, a Diagnostic Trouble Code (DTC) will be stored in the module. A New Generation Star (NGS) scan tool and Data Link Connector (DLC) may be used for retrieving and clearing DTCs from the modules. DTC may be used for system diagnosis.

NOTE: Terminal No. 7 (Light Blue/White wire) of the DLC goes directly to Remote Anti-Theft Personality (RAP) module, Anti-Lock Brake (ABS) module, air bag diagnostic monitor and Generic Electronic Module (GEM). This wire is referred to as the ISO 9141 communication link circuit No. 70 and provides a means for the scan tool to communicate with these modules by using the DLC.
