DESCRIPTION & OPERATION
Vehicle has 2 module communications networks. The Powertrain Control Module (PCM) and Anti-Lock Brake System/Traction Control (ABS/TC) module (if equipped with traction control) are connected to the multiplex communications network through a pair of twisted wires or BUS. The BUS network is also referred to as Standard Corporate Protocol (SCP). The BUS consists of (+) circuit No. 914 and a (-) circuit No. 915. The air bag diagnostic monitor and all other optional modules, the Generic Electronic Module (GEM) and Anti-Lock Brake System (ABS) control module (on models not equipped with traction control), are connected to the ISO 9141 diagnostic communications network through a single wire (circuit No. 70). Both networks are connected to the Data Link Connector (DLC). This article is used to diagnose BUS and ISO communications network circuit faults. For module locations, see COMPONENT LOCATIONS table.
