Cat Data LinkRecommended Actions
Start the engine. If the engine starts, but the ECM will not communicate with Cat ET, continue with this procedure. If the engine will not start, refer to Troubleshooting, "Engine Cranks but Will Not Start". If the engine will not crank, refer to Troubleshooting, "Engine Will Not Crank". Configuration for the Communications Adapter
Access "Preferences" under the "Utilities" menu on Cat ET.
Verify that the correct "Communications Interface Device" is selected.
Verify that the correct port is selected for use by the communication adapter. Note: The most commonly used port is "COM 1".
Check for any hardware that is utilizing the same port as the communications adapter. If any devices are configured to use the same port, exit or close the software programs for that device. Electrical Connectors
Check for correct installation of the J1/P1 and J2/P2 ECM connectors and of the service tool connector. Refer to Troubleshooting, "Inspecting Electrical Connectors".Communication Adapter and/or Cables
If you are using a "Communication Adapter II", ensure that the firmware and software for the communication adapter are the most current files that are available. If the firmware and software do not match, the communication adapter will not communicate with Cat ET.
Disconnect the communication adapter and the cables from the service tool connector. Reconnect the communication adapter to the service tool connector.
Verify that the correct cable is being used between the communication adapter and the service tool connector. Refer to Troubleshooting, "Electronic Service Tools". Electrical Power Supply to the Service Tool Connector
Verify that battery voltage is present between terminals A and B of the service tool connector. If the communication adapter is not receiving power, the display on the communication adapter will be blank.Cat ET and Related Hardware
In order to eliminate Cat ET and the related hardware as the problem, connect Cat ET to a different engine. If the same problem occurs on a different engine, check Cat ET and the related hardware in order to determine the cause of the problem.Electrical Power Supply to the Electronic Control Module (ECM)
Check power to the ECM. Refer to Troubleshooting, "Electrical Power Supply".Note: If the ECM is not receiving battery voltage, the ECM will not communicate.Flash File
Ensure that the correct flash file is properly installed in the ECM.Note: The new ECM does not have a flash file. The engine will not start and the engine will not communicate with Cat ET until the flash file has been installed. Refer to Troubleshooting, "Flash Programming".Cat Data Link
Troubleshoot the Cat Data Link for possible problems. Refer to Troubleshooting, "Cat Data Link".
