Detroit Diesel Diagnostic Link (DDDL) Troubleshooting Guide

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The “Feature not Include” error in DDDL arises from incompatibility with the outdated .HLP help file format. Modern Windows systems require the .CHM format for troubleshooting manuals. To fix this:

1. Download the correct .CHM troubleshooting manual (e.g., for DDEC II-IV, DDEC V, or MBE) from the DDDL support page.
2. Save the downloaded file to: C:Program Files (x86)Detroit DieselDiagnostic.
3. Double-click the .CHM file (e.g., TShoot234.chm, TShootV.chm, or TShootMBE.chm) to verify compatibility.
4. Create a desktop shortcut for easy access:
   • Right-click on your desktop and select “New” > “Shortcut.”
   • Enter the file path: C:Program Files (x86)Detroit DieselDiagnostic[filename].chm.
   • Name the shortcut descriptively (e.g., “DDEC II TS Guide”).
5. Use this shortcut to access the DDDL troubleshooting manual.

Addressing the “Wrong Connection Type” Error

The “Wrong Connection Type” error indicates a communication problem between DDDL and the engine. This can be due to several reasons:

1. Incorrect Interface Setup in DRS:

   • Navigate to: “Start” > “All Programs” > “Detroit Diesel” > “DRS Comm Settings.”
   • Ensure “Protocol” is set to “J1708.”
   • Set “Interface” to “USB Link2” if using a Nexiq USB Link2.
   • Set “Baud Rate” to “9600.”
   • Click “Ok.”

2. Incorrect Network Connection in DDC:

   • Go to: “Start” > “All Programs” > “Detroit Diesel” > “DDC Mainframe Communications.”
   • Click “Update Logon Parameters.”
   • Verify that “Connect via Internet” is selected. If not, select it and click “Save.”

3. Faulty or Incorrect Cable Connection: Ensure the cable is properly connected. For instance, when programming a PLD/MR2, connect directly to the PLD on the bench, not through other devices. Direct connection ensures proper communication for programming and diagnostics.

Conclusion

By following these steps, you can effectively resolve the “Feature not Include” and “Wrong Connection Type” errors in Detroit Diesel Diagnostic Link (DDDL). Ensuring proper file formats and communication settings are essential for accurate diagnostics and efficient troubleshooting of Detroit Diesel engines. Using the correct procedures will minimize downtime and keep your Detroit Diesel engines running smoothly.
