Troubleshooting Test Steps Values Results
1. Engine Start Up
Communication problem
Result: Engine starts, but the ECM will not communicate with Cat ET. Proceed to Test Step 2.
Result:Engine will not start Refer to Troubleshootings, "Engine Cranks but Will Not Start".
Result: Engine will not crank. Refer to Troubleshooting, "Engine Will Not Crank".
2. Configuration for the communications adapter
A. Access "Preferences" under the "Utilities" menu on Cat ET.
B. Verify that the correct "Communications Interface Device" is selected.
C. Verify that the correct port is selected for use by the communication adapter.
Note: The most commonly used port is "COM 1".
D. Check for any hardware that is utilizing the same port as the communications adapter.
Cat ET
Result: The incorrect "Communications Interface Device" is not selected.
Repair: Select the correct "Communications Interface Device".
Result: The correct "Communication Interface Device" is selected.
Result: The incorrect port was selected.
Repair: Select the correct port for the communication adapter.
The correct port was selected. Proceed to Test Step 3.
Note: The most commonly used port is "COM 1".
Result: If any devices are configured to use the same port, exit or close the software programs for that device.
3. Check for correct installation of the J1/P1, and J2/P2 ECM connectors and of the service tool connector.
ECM
Result: Connectors are installed incorrectly.
A. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect"
Repair: Correct the installation issue. Return to service.
Result: Connectors are installed correctly. Proceed to Test Step 4.
4. Check that the Version of the Firmware and driver files for the Communication Adapter has the Most Current Files that are Available.
A. Verify that the correct cable is being used between the communication adapter and the service tool connector.
Firmware
Result: If the firmware and driver files do not match, the communication adapter will not communicate with Cat ET.
Repair: Disconnect the communication adapter and the cable from the service tool connector. Reconnector the communication adapter to the service tool connector.
Result: Refer to electronic troubleshooting Troubleshooting, "Electronic Service Tools".
5. Check the Electrical Power to the Communication Adapter
A. Check for battery voltage at the service tool connector between terminals A and B.
Electrical power
Result: Communication Adapter is not receiving power, and the display on the Communication Adapter is blank.
Repair: Inspect the wiring and fuses. Determine the cause of the missing voltage and Make the necessary repairs.
Repair: Battery voltage is present at terminals A and B.
Proceed to Test Step 6.
6. Connect Cat ET to a different engine in order to eliminate Cat ET and the related hardware as the problem.
Cat ET
Result: Connected Cat ET and other hardware to another engine and still have problem.
Repair: Inspect Cat ET and related hardware to determine the cause of the problem.
Result: Connected Cat ET and other hardware to another engine and is working.
Proceed To Test Step 7.
7. Check power to the ECM.
ECM
Result:Battery voltage is not present at ECM.
Note: If the ECM is not receiving battery voltage, the ECM will not Communicate.
Repair: Inspect the wiring and fuses. Determine the cause of the missing voltage. Make the necessary repairs.
Refer to the diagnostic functional test Troubleshooting, "Electrical Power Supply Circuit - Test. "
Result: ECM is receiving battery voltage.
Proceed to Test Step 8.
8. Ensure that the correct flash file is properly installed in the ECM
Flash File
Result: Flash file is not installed properly in the ECM.
Note: A new ECM is not programmed to any specific engine until a flash file has been installed. The engine will not start and the engine will not communicate with Cat ET until the flash file has been downloaded. Refer to programming parameters Troubleshooting, "Flash Programming".
Repair: Download the correct flash file and install properly to the ECM.
Result: The flash file is correct and properly installed in the ECM.
Proceed to Test Step 9.
9. Troubleshoot the Cat Data Link for possible problems.
