- This pertains to the status of a fault or to the status of a service code. When the fault is active, the fault is currently present.Armed - This is a state of the security system when the machine is disabled.+Battery - This pertains to any of the harness wiring which is part of the circuit that connects to the positive battery post.Cat data link - The Cat data link is an electrical connection for communication with onboard devices that use the Data Link (ECM and service tools such as Caterpillar Electronic Technician). The Cat data link is also the medium that is used for programming with Caterpillar service tools and for troubleshooting with Caterpillar service tools.Caterpillar Electronic Technician (ET) - This is a diagnostic service tool for a personal computer (PC). Circuit - A circuit is a continuous path along a conductor for the flow of electrical current. A circuit goes from an electrical source, through various components, and back to the electrical source.Clear - This pertains to removing diagnostic information from the memory of the ECM. Before clearing a fault, the fault must not be active.Communication Adapter - The communication adapter provides a communication link between the ECM and the ET. The adapter converts Cat data link communication to RS-232 communication or to ATA data link communication and vice versa.Component Identifier (CID) - A CID is a code that is used to identify a particular component. The CID is a four digit code.Connector Contact - A connector contact is the component that actually makes the electrical connection between the harness connector and another connector plug. Connector contacts are either pins or sockets.Detected Fault - This is a fault that has been found by the ECM. The fault is recorded and diagnostic information is available in the service mode.Disarmed - This is a state of the security system when the machine is able to operate normally.ECM - The ECM is the acronym for the electronic control module. Electronic Control Module - The portion of the MSS that contains the microprocessor and memoryEID - Event IdentifierEvent - The ECM recognizes the occurrence of an abnormal machine operation. When a combination of signals arrive at the ECM, the ECM decides when the machine is operating abnormally. Events are logged by the ECM and events are viewed by using a service tool. Exciter Coil - The exciter coil is a small coil of fine wire. The wire is molded into the bezel of a keyswitch with harness wiring. The exciter coil provides a path of communication. The electronic key and the electronic control module communicate via radio frequency.Fault - A fault is a failure of a component which is monitored by the ECM. The ECM detects a fault when a signal at the ECM connector is abnormal. An FMI and a CID identify the type of fault.Floating - The input of the ECM is not connected to a source of positive voltage or ground. Failure Mode Identifier (FMI) - An
