Troubleshooting Test Steps Values Results
1. Configuration of the Communications Adapter
A. Access "Preferences" under the "Utilities" menu on the electronic service tool.
B. Check for hardware that uses the same ports as the communications adaptor.
Communications adapter configuration
Result: The correct "Communications Interface Device" is not selected.
Repair: Select the correct "Communications Interface Device".
Result: The correct port is not selected for use by the communication adapter.
Repair: Select the correct port for use by the communication adapter.
Note: The most commonly used port is "COM 1".
Result: Other hardware is sharing the same port with the communications adaptor.
Repair: Exit or close the software programs for that device.
Result: The communications adaptor is correctly configured.
Proceed to Test Step 2.
2. Electrical Connectors
A. Check for correct installation of the P1 and P2 ECM connectors and of the connector for the electronic service tool.
Electrical connectors
Result: The connectors are not correctly installed.
Repair: Repair or replace the connectors, as necessary.
Result: The connectors are OK.
Proceed to Test Step 3.
3. Communication Adapter and/or Cables
A. Check that the firmware and driver files are the most current files for the type of communication adapter that is being used.
Verify that the correct cable is being used between the communication adapter and the diagnostic connector.
B. Disconnect and then reconnect the cable that attaches the communication adapter to the diagnostic connector.
C. Check the operating system on the laptop computer.
Comms adaptor and cables

Result: The laptop computer has a Windows operating system.
Repair: Restart the laptop computer in order to eliminate the possibility of a conflict in the software.
Result: The adaptor and cables are OK.
Proceed to Test Step 4.
4. Electrical Power Supply to the Diagnostic Connector
A. Use a multimeter to check that battery voltage is present between terminals A and B of the diagnostic connector.
Note: If the communication adapter is not receiving power, the LED display on the communication adapter will be off.
Electrical power
Result: Battery voltage is not present between terminals A and B of the diagnostic connector.
Repair: Investigate the cause and repair, as necessary.
Result: Battery voltage is present between terminals A and B of the diagnostic connector.
Proceed to Test Step 5.
5. Electronic Service Tool and Related Hardware
A. Connect the electronic service tool to a different engine.
Note: This process eliminates the electronic service tool and the related hardware as the fault.
Hardware
Result: The same fault occurs on a different engine.
Repair: Check the electronic service tool and the related hardware for faults.
Result: The fault does not occur on a different engine.
Proceed to Test Step 6.
6. Electrical Power Supply to the Electronic Control Module (ECM)
A. Check the power supply to the ECM. Refer to Troubleshooting, "Electrical Power Supply - Test".
Note: If the ECM is not receiving battery voltage, the ECM will not communicate.
Power to ECM
Result: The power supply to the ECM is incorrect.
Repair: Investigate the cause and repair, as necessary.
Result: The power supply to the ECM is OK.
