CONNECTOR 3717193 - Caterpillar

engine incorporates a Cat Data Link in order 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 Caterpillar Electronic Technician (ET).Typical information about the engine or about the machine that is monitored and available on the data link includes the following items:
Aftercooler temperature
Air filter restriction
Air inlet temperature
