Detroit Diesel Diagnostic Link (DDDL) Troubleshooting Guide

The Detroit Diesel Diagnostic Link (DDDL) is a crucial tool for diagnosing and troubleshooting issues in Detroit Diesel engines. However, users may encounter errors like “Feature not Include” or “Wrong Connection Type.” This guide provides solutions to these common DDDL problems, ensuring a smooth diagnostic experience.

Resolving the “Feature not Include” Error

The “Feature not Include” error in DDDL arises from incompatibility with legacy troubleshooting manual files (.HLP format). Modern Windows systems (7, 8, and 10) no longer support this format. The solution is to utilize the supported .CHM file format.

To implement the solution:

1. Download the Correct Manual: Download the appropriate troubleshooting manual (.CHM format) for your specific Detroit Diesel engine (e.g., DDEC II-IV, DDEC V, or MBE) from the DDDL support page.

2. Save to the Designated Folder: Save the downloaded .CHM file to the following directory: C:Program Files (x86)Detroit DieselDiagnostic.

3. Verify Compatibility: Double-click the saved .CHM file (e.g., TShoot234.chm, TShootV.chm, or TShootMBE.chm) to ensure it opens correctly, confirming compatibility.

4. Create a Desktop Shortcut: For convenient access, create a shortcut on your desktop: Right-click on the desktop, select “New,” then “Shortcut.” Enter the file path: C:Program Files (x86)Detroit DieselDiagnostic[filename].chm (replace [filename] with the actual file name). Name the shortcut descriptively (e.g., “DDEC II TS Guide”) and click “Finish.”

5. Access the Troubleshooting Guide: Use the desktop shortcut to quickly access the DDDL troubleshooting manual whenever needed. This provides a user-friendly solution to the outdated file format issue.

Addressing the “Wrong Connection Type” Error

The “Wrong Connection Type” error in DDDL can stem from several connection-related issues:

1. Incorrect Interface Setup: Verify the Detroit Diesel Diagnostic and Repair Software (DRS) communication settings. Navigate to: Start Menu > All Programs > Detroit Diesel > DRS Comm Settings. Ensure the settings are: Protocol=J1708, Interface=USB Link2 (if using a Nexiq USB Link2 adapter), and Baud Rate=9600. Click “OK” to save changes.

2. Incorrect Network Connection: Confirm the correct network connection within the DDC Mainframe Communications. Go to: Start Menu > All Programs > Detroit Diesel > DDC Mainframe Communications. Click “Update Logon Parameters” and ensure “Connect via Internet” is selected. Click “Save” if any changes were made. This ensures the software is attempting to connect through the appropriate network.

3. Faulty Cable Connection: Physically inspect the connection between the diagnostic tool and the engine. Ensure the cable is properly connected at both ends and is free from damage. For specific applications like programming a PLD/MR2, a direct connection to the PLD on the bench is required, bypassing any network connections.

Conclusion

By addressing these common connection and compatibility issues, users can effectively utilize the Detroit Diesel Diagnostic Link (DDDL) for accurate diagnostics and troubleshooting. Correcting these errors ensures efficient repairs and minimizes downtime. Remember to consult the official Detroit Diesel documentation for detailed information specific to your engine model and diagnostic tool.
