LINES GP-HOIST 2656125 - Caterpillar

engine incorporates a Cat Data Link. The data link is used to communicate with other devices that are based on a microprocessor.The data link can reduce the duplication of sensors within the system by allowing controls to share information. The data link is used to communicate information about the engine to other electronic control systems. The data link is also used to interface with the electronic service tool.The information about the engine that is monitored and available on the data link includes the following items (typical example):
Air filter restriction
Atmospheric pressure
Boost pressure
Cold mode status
Coolant temperature
Crankcase pressure
Diagnostic messages
Supply voltage for the Electronic Control Module (ECM)
Engine identification
Engine speed (actual rpm)
Engine speed (desired rpm)
Engine systems status
Engine warning system
Exhaust temperature
Filtered oil pressure
Fuel pressure
Maximum air filter restriction
Oil pressure
Percent throttle position
Rated fuel limit
Timing cal enable/status
Total fuel consumption
Turbocharger inlet pressure
Turbocharger outlet pressureThe electronic service tool plugs into the connector for the data link in order to communicate with the ECM. The communication adapter is installed in series between the electronic service tool and the data link connector. The communication adapter converts data that is in the language from the data link. This language is converted to a language that is used by the electronic service tool. The data link connector is located on the engine harness. The electronic service tool can also be used to display the values of all the information for monitoring of engine operation in real time.
