TOOL 7Y5493 - Caterpillar

CAT Data Link is a communication link that is used for the movement of data between electronic controls. The CAT Data Link allows communication between the power train electronic control module (ECM) and the Caterpillar Monitoring System. The CAT Data Link is bidirectional. The CAT Data Link allows the power train ECM to input information. The CAT Data Link allows the power train ECM to output information. The CAT Data Link is not a visible component. The CAT Data Link consists of the following parts: internal circuits for power train ECM, the related harness wiring and the service tool connector. The CAT Data Link and the power train ECM are connected at pin-out J1-3 and pin-out J1-9.The power train ECM and the Caterpillar Monitoring System use data that is sent back and forth on the CAT Data Link. The following information is some of the information that is shared:
The power train ECM receives a service command from the Caterpillar Monitoring System. The service command can change the operating mode of the power train electronic control system. The power train ECM receives a service command from the Caterpillar Monitoring System in order to change the operating modes of the power train electronic control system. The service command can direct the power train ECM to read service codes that are stored in the ECM memory. The service command can direct the power train ECM to clear service codes that are stored in the ECM memory.
The power train ECM receives the harness code input from the Caterpillar Monitoring System. The power train ECM determines the sales model of the machine from the harness code input.
The power train ECM sends signals to the Caterpillar Monitoring System. The Caterpillar Monitoring System uses the signals to report on the status of the power train electronic control system. The Caterpillar Monitoring System alerts the operator of the status by illuminating the corresponding alert indicator.
The power train ECM sends the parking brake status to the Caterpillar Monitoring System. The power train ECM sends the direction of the transmission to the Caterpillar Monitoring System. The power train ECM sends the status of transmission speed to the Caterpillar Monitoring System. The Caterpillar Monitoring System uses this information to display the direction of the transmission and the speed of the transmission. The Caterpillar Monitoring System uses this information in order to show the operator if the parking brake is engaged or disengaged.Note: All electronic control modules that use the CAT Data Link have a module identifier (MID). These module identifiers are used on the 988G Wheel Loader:Module Identifiers (MID) Caterpillar Monitoring System ... 030Engine ECM ... 036Power Train ECM ... 081Reference: For more information about theCaterpillar Monitoring System, refer to the Service Manual module Systems Operation, "Caterpillar Monitoring System" for the machine that is being serviced.Reference: For more information on the power train electronic control module (ECM), refer to the Service Manual module Systems Operation, "Electronic Control Module (Power Train)" for the machine that is being serviced.
