Description & Operation

WARNING: This page is about a different car, the 2001 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.

Module communications network provides ability 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 each module. Bus network is also referred to as Standard Corporate Protocol (SCP). Bus consists of a (+) circuit No. 914 and a (-) circuit No. 915. Bus is routed throughout vehicle to each module except Restraints Control Module (RCM).

Restraint Control Module (RCM) does not use bus to communicate with other modules. Restraints Control Module is connected to International Standards Organization (ISO) 9141 diagnostic communications network through a single wire (circuit No. 70). Both networks are connected to Data Link Connector (DLC). This article is used to diagnose bus and ISO communications network circuit faults.
