USB-Link Troubleshooting Procedure

USB-Link, USB-Link 2, and USB-Link 3 Troubleshooting Procedure

  1. Open the NEXIQ Device Tester.
    Go through each drop-down menu one at a time and click Test for each selection.

  2. Verify data communication.
    Confirm that you are receiving data on:

    • J1708

    • J1939 Channel 1

    • J1939 Channel 2

  3. Important:
    If you are not receiving data in the Device Tester, you will not receive data in any program that uses the USB-Link.

Basic Checks

  • Bypass any electronic driver log (if applicable).

  • Ensure the vehicle key is in the ON position.

  • Replace the USB cable between the laptop and the NEXIQ adapter.

  • Check (pin out) the 6-pin or 9-pin vehicle diagnostic port to verify proper voltage and signal at the connector.

  • Make sure that you have the correct driver install for your adapter.

  • Cloned USBLINK2 adapters use the original USBLINK driver. If you need this drive email us HeavyTruckSoftware@gmail.com

DDDL REACTIVATION

Troubleshooting: Activator or License Error

In some cases, this issue may occur approximately every 364 days from the original activation date. If you encounter this error, follow the steps below to reactivate the software.

Important Note

Make sure you are using the correct icon named DDDL_START.
If you are not using the correct shortcut, you may receive an activation error.

Sometimes Windows Defender may remove or quarantine the correct shortcut or related files.

If this happens, you have two options:

  1. Open Windows Defender and restore the deleted or quarantined file.

  2. Contact us and we can remote into your system and restore it for you.

We take steps to minimize this issue, but it is the end user’s responsibility to monitor Windows Defender to ensure it has not removed required files.

Steps to Reactivate

  1. Right-click on the DDDL_START icon.

  2. Select “Go to file location.”

  3. When the folder opens, locate the .exe file that contains the word “activator.”

  4. Right-click the file.

  5. Select “Run as administrator.”

  6. Click “Activate.”

Additional Information

We do not configure any activators to expire automatically.

A license may become invalid only if:

  • A Windows operating system update occurs, or

  • A hardware change is detected.

Hardware Level 4 Message

If you receive a Hardware Level 4 message, it means the system has detected a hardware change.

In most cases:

  1. Run the activator again as administrator following the steps above.

  2. This will restore the license.

If the issue persists, please contact us so we can generate a new license file.

ALLISON DOC REACTIVATION

 Unfortunately, this occurs every 364 days from the original activation date.

Please follow these steps:

  1. Right-click the DOC_START icon.

  2. Select Go to file location.

  3. Locate the appropriate activator based on your Allison DOC version:

    • Allison DOC 2019 → A191.EXE

    • Allison DOC 2023 → A231.EXE

    • Allison DOC 2024 → A241_Activator.EXE

  4. Right-click the applicable file and select Run as administrator.

  5. In the activator window, change the year to 2040, then click Activate at the top of the window.

Please note: We do not configure the .lic file to expire in any activator. The only factors that can invalidate a license file are an operating system update or a hardware change.

Thank you.
