Description & Operation: Notes
WARNING: This page is about a different car, the 1997 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.
The module communications network provides the ability for a 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 each module. The BUS consists of a (+) circuit No. 914 and a (-) circuit No. 915. The BUS is routed throughout the vehicle to each module except the air bag diagnostic monitor. See Fig 1
. The air bag diagnostic monitor does not use the BUS to communicate with other modules. 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 tester and Data Link Connector (DLC) may be used for retrieving and clearing DTCs from the module. DTC may be used for system diagnosis.
NOTE:
Terminal No. 7 (Light Blue/White wire) on DLC goes directly to air bag diagnostic monitor. This wire is referred to as the ISO 9141 communication link circuit No. 70 and provides a means for the scan tester to communicate with the air bag diagnostic monitor by using the DLC.
