Use this workflow to install the Vehicle Gateway (VG54 or VG55) with the diagnostic cable CBL-VG-DIZU on an Isuzu heavy-duty vehicle.

What You'll Need

	Quantity	Description
	1	Vehicle Gateway
	1	Isuzu Heavy Duty Diagnostic Cable (CBL-VG-DIZU) OBD2 male connector 18-pin female connector 18-pin male connector OBD2 female connector (spare) Gateway connector
	2	Short-narrow cable ties (cable bag)
	2	Long-narrow cable ties (cable bag)

Install the VG55 with the CBL-VG-DIZU Cable

1. If you have not already done so, activate the device in the Samsara dashboard using one of the following methods:

   • Activate your device with the Samsara Fleet App (see Streamline Hardware Installation with the Samsara Fleet App). You can also confirm cable compatibility with your vehicle by scanning or manually entering the VIN for the vehicle.

   • Go to https://cloud.samsara.com/activate or click the link in your Order Shipped email.

     

2. Power off the vehicle before beginning the installation.

3. Locate and remove the dashboard panel to access the vehicle’s diagnostic port.

   

4. Connect the 18-pin female connector on the Samsara cable to the vehicle’s diagnostic port. Use the provided zip tie to secure the unused male connector for future use with third-party devices.

   

5. Route the Samsara cable toward the driver’s side and locate the OBD2 port.

   

6. For vehicles operating outside the State of California: Follow these instructions to attach the Y splitter cable. If your vehicle operates in the State of California, proceed to the next step.

   Note

   In certain cases, regulations in the State of California may prohibit the installation of a Y splitter cable if it involves relocating the in-vehicle diagnostic connector. In these cases, skip to the next step to plug-in the harness without relocating the diagnostic connector.

   1. With the engine off, locate the vehicle’s diagnostic port. Detach the port from its original mounting location in the vehicle.

      

      Typically, the port is located on or near the driver’s side kick panel.

   2. Connect the Samsara cable to the detached diagnostic port after it has been removed from the vehicle panel.

      

      The vehicle’s diagnostics will remain accessible using the additional port on the Samsara cable.

   3. Fasten the unconnected port to the original port location in the vehicle.

      

      Confirm that the VG and all cables are clear of the vehicle’s pedals, steering linkage, and other moving parts.

   4. Proceed to connecting the VG.

7. For vehicles operating in the State of California: Follow the instructions in this step to attach the Y splitter connector.

   1. With the engine turned off, find the vehicle’s diagnostic port, typically located on or near the driver’s side kick panel.

      

   2. Use a small, narrow cable tie from the cable bag to fasten the shorter cable (which has the spare diagnostic connector) to the main cable. Place the cable tie near the spare diagnostic connector for secure fastening.

      The spare diagnostic connector is not used for this installation type. However, we recommend keeping the bracket on the spare diagnostic connector to allow for flexibility in future configurations.

      

   3. Connect the main diagnostic connector of the Samsara cable to the vehicle’s diagnostic port.

      

8. Plug the 16-pin diagnostics/power connector into the VG. It will click when fully inserted.

   

9. Turn on your vehicle and verify that the VG indicator light turns green; this can take 1-3 minutes.

   

   Note

   The indicator light may initially display green, but then change again temporarily (for example, such as when the VG connects, but then downloads and installs an update).

   If the indicator light turns amber, ensure that you are installing the VG in an area with good cellular reception.

   If the indicator light turns blue, turn your vehicle off and then back on before proceeding to the next step.

   Note

   In some cases, you may need to take a short drive to enable the VG to retrieve diagnostics and transition the indicator light from blue to green.

10. If you are using the Samsara Fleet App to set up the VG, you can return to the app to verify the installation after the indicator light turns green.

    1. Ensure the vehicle is powered on and wait for all of the checks in the app to pass.

    2. Add vehicle details like the license plate number in the app.

11. Plug in the cable connectors for any applicable accessory devices (USB or 8-pin AUX devices).

    

    Access the accessory device ports by removing and properly discarding the port covers.

12. Using the narrow cable ties included in the VG box, secure the power cable and any accessory device cables.

    Note

    Using the wide cable ties which come with the diagnostics cable is not recommended as they may cause interference with the cable connections.

    

    Tip

    Secure the VG tightly to the vehicle. A loose VG may cause inconsistent detection of Harsh Events. If possible, avoid surrounding the VG with metal parts as this could interfere with wireless or GPS connectivity.

13. Secure the power cable and any accessory device cables using the cable ties included in the cable bag.

    

    Tip

    Avoid wrapping the power and device cables around the gateway. Avoid tight bends in the cables.

14. If you experience any issues during installation, visit the Samsara Help Center to find solutions to most issues.
