32 RENR5042-02 Troubleshooting Section 2. Verify that the correct “Communications Interface Device” is selected. Electrical Power Supply to the Electronic Control Module (ECM) 3. Verify that the correct port is selected for use by the communication adapter. Check power to the ECM. Refer to Troubleshooting, “Electrical Power Supply Circuit - Test”. Note: The most commonly used port is “COM 1”. Note: If the ECM is not receiving battery voltage, the ECM will not communicate. 4. 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.
Flash File Ensure that the correct flash file is properly installed in the ECM. Electrical Connectors Check for correct installation of the J1/P1 and J2/P2 ECM connectors and of the service tool connector. Refer to Troubleshooting, “Electrical Connectors - Inspect”. 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”. Communication Adapter and/or Cables Cat Data Link 1. If you are using a “Communication Adapter II”, ensure that the firmware and driver files for the communication adapter are the most current files that are available.
If the firmware and driver files do not match, the communication adapter will not communicate with Cat ET. Troubleshoot the Cat Data Link for possible problems. Refer to Troubleshooting, “Cat Data Link Circuit - Test”. i02290294 Engine Cranks but Will Not Start 2. Disconnect the communication adapter and the cables from the service tool connector. Reconnect the communication adapter to the service tool connector. SMCS Code: 1000-035 3. Verify that the correct cable is being used between the communication adapter and the service tool connector. Refer to Troubleshooting, “Electronic Service Tools”.
Probable Causes Electrical power to the Electronic Control Module (ECM) Electrical Power Supply to the Service Tool Connector Flash file Remote shutdown switch 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. Air shutoff circuit Starting motor solenoid or starting circuit Cat ET and Related Hardware Engine speed/timing sensors 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 connections to the electronic unit injector Fuel supply Combustion problem
