Volvo Truck Diagnostics (Ultimate Guide To Fault Finding!)

Diagnostics are necessary for trucks and semi-trucks to determine specific issues.

By conducting diagnostics, you will know how to fix the fault of your semi-truck experience.

In this article, you will focus on Volvo truck diagnostic tools and fault codes to help you out on how to fix it.

Here’s a Short Summary of How to Run Volvo Truck Diagnostics:

To run diagnostics in a Volvo truck, a diagnostic tool is used to communicate to the truck’s computer system, engine, and other parts. The diagnostic tool is connected to the truck’s diagnostic port and, when run, will show you specific fault codes that correspond to the current issues of the truck.

Volvo Truck Diagnostic Port

The diagnostic port is where you connect the diagnostic tool to access the truck’s computer system and run the necessary diagnostic to fix some faulty issues.

What Diagnostic Port Does a Volvo Truck Have?

The Volvo Truck uses three main types of diagnostic ports. These are the OBD2, 6-pin (J1708), and the 9-pin (J1939).

The 6-pin port is for the 2000 and older models with a Volvo engine.

The 6-pin or 9-pin type I black is for 2000 to 2004 models with a Volvo engine. It is also the same for the 2006-2016 truck models with a Cummins engine.

The 9-pin type I black is for 2005 to 2013 models with a Volvo engine.

The OBD2 port 16-pin is for models 2014 to the current year with a Volvo engine. It also works for 2006 to 2014 Volvo truck models with a Volvo D series engine.

Lastly, the 9-pin type II green port is for 2016 to newer models of Volvo trucks with a Cummins engine.

Do you Need a 9-pin to OBD2 Adapter for your Volvo Truck?

Knowing your Volvo truck’s diagnostic port type is always a good practice. If you need to conduct diagnostics to find out some issues, you can connect the diagnostic tool properly.

Based on the info above, the 2000-2013 Volvo engine and the 2006-2016 Cummins engine use the 9-pin type port.

If your truck belongs to these models and your diagnostic tool has the OBD2 port cable, you can use a 9-pin to OBD2 adapter to diagnose your Volvo truck.

Where is the Diagnostic Port on a Volvo Truck?

In general, you can find the diagnostic port of your Volvo truck in the area below the steering wheel. It is usually located on the left side, behind the dashboard.

Volvo Truck Diagnostic Tool

Volvo Trucks uses Premium Tech Tool (PTT) diagnostic application. It is a Windows-based diagnostic tool designed to conduct fast and accurate readings.

What is the Volvo Tech Tool?

The Volvo Tech Tool is the one that supports the diagnostic procedure on your truck’s computer system.

This software or tool makes repairs and maintenance more accurate and effective.

You can use the Volvo Tech Tool either online or offline or not connected to the central system of your truck, so you can still perform diagnosis while even on the roadside or far from a repair shop.

How do I Update my Volvo Tech Tool?

The diagnostic will work more accurately if you use the latest update of your Volvo Tech Tool.

You can follow these steps to update it:

1. Access the Client Update Agent on your PC. You can find its icon in the lower right corner of the screen.

2. Open the Client Update Window and click the “Search for updates” button.

3. If an “update” is already available, click on the download button.

4. To automatically install the updates, ensure you click the checkbox for it.

5. As the updates start downloading or installing, you will see the progress information. You can close the window once done.

6. Launch the Tech Tool from your truck without connecting it to your computer.

7. Click on the Tech Tool on the drop-down menu. Then, click on Update Product Information.

8. A window will prompt on the screen, indicating that the action is now making progress.

9. Once completed, a status window will appear, showing a successful update to the system.

Volvo Truck Diagnostic Software

A diagnostic tool needs software to conduct accurate and fast diagnostics on your Volvo truck.

What diagnostic software does Volvo use?

Volvo trucks often use the Truck Diagnostic System software solution or TDS for proper diagnosis of repairs and maintenance needed for your truck.

Do Volvo D12 and D13 use the same diagnostic software?

Volvo D12 and D13 engines may use similar diagnostic software since they have similar tools and ports installed.

Volvo Truck Diagnostic Fault Codes

When diagnosing your truck, you will notice that it will only show you codes representing the fault or issue.

There are a lot of fault codes available. Still, you may want to familiarize yourself with the most common ones when driving a Volvo truck.

How do I Get the Code for my Volvo Truck?

To get the code when diagnosing your Volvo truck, ensure it is on neutral first while the parking brake is on. After you activate the parking brake, follow these steps.

  1. Check the lever on the right side of the steering wheel. On its end, you will see two buttons, the escape and enter buttons. Push the escape button and check your truck’s dashboard.
  2. Then press the enter button for you to see a menu. Press the down button until you see the Diagnostics menu. Press enter and view active faults. You will then see several ECUs.
  3. Check engine ECU, and you may see an error. To know if there are other errors, look at the number on the upper right to see the total number of faults on your truck.
  4. To check on the other errors, press the up or down button to scroll on the screen again. To get the code, check the number combination on the right side of DTC. Typically, it starts with the letter “P” or sometimes “U.”
  5. Press escape and check the other ECUs to see if they also have errors. Once you get the codes, you can check the list below to know what the fault codes mean.

What Do the Fault Codes Mean?

Some people will already know the fault or error as soon as they see the codes. But for most drivers, it may not be the case.

To help you out, here’s a list of typical fault codes for Volvo trucks and their meanings:
