CYLINDER AS 3240501 - Caterpillar

When only the alert indicator is illuminated, a Warning Category 1 is indicated.Alternating Current (AC) - An alternating current is electrical current which flows in both directions alternately.Ampere - Amperes are the unit of measure for the flow of electrical current in a circuit.+Battery - This pertains to any of the harness wiring which is part of the circuit that connects to the + battery post.+V - +V is a constant voltage that is supplied to a component. This voltage provides electrical power for the component's operation. +V is provided by an electronic control module or the battery.Cat Data Link - The Cat Data Link is an electrical connection for communication with onboard devices that use the Data Link (ECM, CMS, VIMS, electronic power train, electronic dashboards 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). This software program is designed to replace the ECAP service tool.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.Code - See Diagnostic Codes.Component Identifier (CID) - A CID is a code that is used to identify a particular component.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.Conductor - A conductor is a substance that can transfer an electrical current.Connector Contact - A connector contact is the component that actually makes the electrical connection between the harness connector and another connector plug.Current - A current is the movement of electricity along a conductor. Current is measured in amperes.Data Event - 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. Data events are logged by the ECM and data events are viewed by using a service tool. Data Link - See “Caterpillar data link”.Deadband - During this portion of the range of movement of a sensor such as the throttle position sensor, the output signal remains constant.Demand Fan Control - This is a system which controls the fan speed according to the coolant temperature. This system is controlled by the engine ECM. The hydraulic fan motor operates at a minimum speed when the coolant temperature is below a specific value. Fan speed increases as the coolant temperature increases.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.Diagnostic - This pertains to the monitoring of information that is abnormal and/or the recording of information that is abnormal. Diagnostic information can be accessed from the service, the status, the tattletale or
