KIT-HYDRAULIC CYLINDER 5599858 - Caterpillar

The electronic control system provides drivers capable of sinking or sourcing 300 mAmp, which can be used to drive a relay, audible or visual alarm to annunciate the various diagnostic conditions.Lamp Driver Specifications
Electrical characteristics of the ECM lamp driver circuits, used for the Diagnostic Lamp and the Warning Lamp, have a maximum current draw of 0.30 amperes (300 mAmp). The design does not have diagnostic codes associated with either lamp circuit.
Figure 1.10 Low Side Driver (Sinking Driver)These circuits are low side drivers because the ECM provides a path to ground to activate the lamp or other devices connected to it. Caterpillar does not require dedicated circuit protection for these circuits.
Figure 1.11 High Side Driver (Sourcing Driver)These circuits are high side drivers because the ECM provides a path to positive battery to activate the lamp or other devices connected to it. Caterpillar does not require dedicated circuit protection for these circuits.Diagnostic Lamp Operation
An OEM installed Diagnostic Lamp is required to indicate a control system malfunction (diagnostic condition) to the operator for diagnosing control system component failures.The Diagnostic Lamp alerts the operator to the presence of Active diagnostic codes (fault conditions) in the electronic control system.Viewing Diagnostic Flash Codes
Caterpillar's proprietary two-digit diagnostic flash codes can be read from the Diagnostic Lamp. Active diagnostic codes may be determined using the Diagnostic Lamp.Count the flashes (this is the first digit), a brief pause will occur, the second digit of the flash code will follow. All active diagnostic codes (occurring since ECM received power) will follow in the same manner with a five second pause between codes. It is suggested the Diagnostic Flash Codes be used only to indicate the nature of a diagnostic code occurrence, not to perform detailed troubleshooting. Troubleshooting should be performed using SAE J1587 CID/FMI Diagnostic Codes obtained using an Electronic Service Tool.Warning Lamp Operation
Caterpillar Engine Monitoring System offers optional OEM installed Warning/Alarm Lamps in order to alert the operator of an engine problem detected by the ECM. The action is furnished by the ECM in order to protect the engine. The lamp output alerts the operator that a predetermined limit has been reached.Turn the keyswitch to the ON position, engine OFF. The Warning Lamps will come ON for five seconds, then turn OFF indicating the lamp circuit is functional.Low Oil Pressure Lamp
The Low Oil Pressure Lamp is used
