Yanmar Engine Diagnostic Service Tool, INDUSTRIAL ENGINES, 0DTNV-G00101 Common Problems This Manual Covers
Yanmar TNV Series diagnostic tool shows no communication when connecting to the engine ECU p. 13
Check the cable connections and verify system power. Verify the CAN communication speed (baud rate) for land applications is set to 500k as outlined on page 12. Inspect the communication IF box to ensure the firmware version is 02.15. Proceed to page 13 to clear any disconnect status.
Manual Section: Starting/Quitting the SoftwareDiagnostic software indicates power supply voltage issues during diagnosis p. 55
Test the battery voltage and inspect all fuses in the main harness. Verify the tool's Source Address (SA) is configured to F0h on page 55. Check the system wiring for shorts or poor grounds to ensure stable supply voltage before clearing the active diagnostic trouble codes.
Manual Section: Tool FunctionsLive data monitor freezes or fails to capture sensor values during engine operation p. 84
Inspect the data logging settings and confirm the sampling frequency default is set to 100 milliseconds as shown on page 84. Ensure your PC meets the display resolution requirement of 1024x768. Restart the application and verify the trigger function initiates data storage properly.
Manual Section: Appendix BCannot force digital output contacts or read analog pulse input values during testing p. 25
Check the EGR Valve Opening Degree Control and ensure the valid range upper limit does not exceed 54 on page 56. Verify your system setting priority standard value is 6 on page 73. Review the diagnostic test values on page 25 to confirm the input device operation.
Manual Section: Main MenuFrequently Asked Questions
How do I reset a Yanmar TNV engine error code?
To reset Yanmar TNV engine error codes, navigate to the "Logged Diagnostic Trouble Codes" screen. You can delete specific logged data items by checking the "Clear" field next to them and clicking the "Clear Logged DTC" button, or clear all logged trouble codes by clicking the "All Clear" button. Active trouble codes will remain on the screen but are actually erased from the ECU when "All Clear" is used.
How do I clear the alarm on a Yanmar TNV engine?
To clear alarms on a Yanmar TNV engine, which are represented by trouble codes, you can either wait for active diagnostic trouble codes to disappear automatically once the cause of the trouble is removed and normal operation is restored, or you can manually clear logged diagnostic trouble codes. Logged codes can be cleared individually by checking the "Clear" field and clicking "Clear Logged DTC," or all at once using the "All Clear" button on page 20.
What does Yanmar TNV error code mean?
Yanmar TNV error codes, also known as Diagnostic Trouble Codes (DTCs), are compliant with SAE J2012. Their meaning is displayed as a "Description" on the "Active Diagnostic Trouble Codes" screen (page 19) or the "Fault Information List" screen (page 21). The "Fault Information List" also provides a "SPN" (Suspect Parameter Number compliant with SAE J1939) and "FMI" (Failure Mode Identifier) for more detailed failure information.
What are the system requirements for operating the YANMAR Engine Diagnostic Service Tool (YDT)?
To operate the YANMAR Engine Diagnostic Service Tool (YDT), a PC/AT compatible computer is required with a display resolution of 1024x768. Supported operating systems include Windows 2000 professional SP1, Windows XP professional, Windows XP Home, Windows XP Tablet PC Edition, and Windows Vista (Home / Business / Enterprise / Ultimate). The communication IF box requires Firmware version 02.15, DLL version 02.00, and API version 02.02.
What are the standard CAN communication speeds for Yanmar TNV industrial engines?
The standard CAN communication speed (baud rate) for Yanmar TNV industrial engines is 250 kbps for marine applications and 500 kbps for land applications. These settings can be configured in the System Setting sub-window, accessible via the Standard tool bar.
