For Kenworth owners and technicians working on 2016 models, understanding the location of the OBD2 port is crucial for diagnostics and telematics device installation. This article from techcarusa.com, your trusted source for auto repair expertise, will pinpoint exactly where to find the OBD2 port on a 2016 Kenworth and provide essential context for its use.
Understanding the OBD2 Port
Before we dive into the specific location on a 2016 Kenworth, let’s clarify what an OBD2 port is and why it matters. OBD2 stands for On-Board Diagnostics II. It’s a standardized port found in most vehicles manufactured after 1996. This port allows access to the vehicle’s computer system for:
- Diagnostics: Mechanics and technicians use OBD2 scanners to read trouble codes, diagnose issues, and monitor vehicle performance.
- Emissions Testing: OBD2 ports are essential for emissions testing, ensuring vehicles meet environmental regulations.
- Telematics and Fleet Management: Devices like Geotab GO, often used in fleet management, connect to the OBD2 port to gather vehicle data for tracking, diagnostics, and more.
For a 2016 Kenworth, which falls under the heavy-duty truck category, the diagnostic port is equally vital. While light-duty vehicles universally adopted the 16-pin OBD2 port, heavy-duty trucks, including Kenworth, may sometimes utilize different port types. However, for a 2016 Kenworth, you’ll primarily be looking for a standard OBD2 port or a similar diagnostic interface.
Locating the OBD2 Port on a 2016 Kenworth
The most common location for the OBD2 port on a 2016 Kenworth truck is typically underneath the dashboard on the driver’s side. Here’s a step-by-step guide to help you find it:
- Driver’s Side Focus: Get into the driver’s seat of your 2016 Kenworth. The OBD2 port is almost always within reach from the driver’s position.
- Dashboard Underside: Look under the dashboard, near the steering column and pedal area. You’re searching for a 16-pin, trapezoid-shaped female connector.
- Kneel and Inspect: You may need to kneel down and use a flashlight to get a better view. The port is usually in a relatively accessible location but could be tucked away slightly.
- Look for Markings: Sometimes, there might be labels or icons near the port indicating it’s the diagnostic connector.

Note: While under the dashboard is the most likely location, Kenworth trucks, especially heavy-duty models, can sometimes have alternative locations. If you can’t find it under the dash, consider these possibilities:
- Center Console Area: Check around the center console, lower section, or inside any compartments.
- Glove Compartment: In rare cases, the OBD2 port might be located inside the glove compartment.
- Engine Compartment (Less Likely for OBD2): While less common for OBD2 in modern trucks, some diagnostic ports could be found in the engine compartment, though these are more likely to be for specific engine diagnostics rather than general OBD2 access.
If you are still unable to locate the OBD2 port:
- Consult your Kenworth Owner’s Manual: The owner’s manual for your 2016 Kenworth should have a section detailing the location of the diagnostic port.
- Contact a Kenworth Dealership or Certified Mechanic: A Kenworth dealer or a mechanic specializing in Kenworth trucks will be able to quickly guide you to the OBD2 port’s location.
OBD2 Port and Telematics Device Installation on Kenworth Trucks
Once you’ve located the OBD2 port on your 2016 Kenworth, you might be planning to use it for a telematics device like a Geotab GO for fleet management or other vehicle tracking purposes.
Harness Considerations for Kenworth: For many vehicles, including heavy-duty trucks like Kenworth, installing a telematics device might require a harness. Based on general compatibility guidelines and for Kenworth models around 2016, you might typically use a HRN-DS09S4 straight harness or a HRN-GS09K2-A T-harness.
However, it’s crucial to verify the specific harness requirements for your 2016 Kenworth model and the telematics device you intend to install. Factors like the exact Kenworth model within the 2016 range and any specific vehicle configurations can influence harness compatibility.
Always confirm compatibility:
- Refer to the Geotab Harness Compatibility Documentation: Geotab and similar telematics providers have detailed compatibility tables that specify the correct harnesses for various vehicle makes, models, and years. Always consult these official documents.
- Use Online Harness Lookup Tools: Many telematics companies offer online tools where you can input your vehicle’s year, make, and model to find the recommended harness.
- Consult with an Authorized Installer: For professional and guaranteed installation, it’s highly recommended to use an authorized installer. They will have the expertise to identify the correct port, choose the right harness, and ensure proper and safe installation.
Important Warnings and Considerations
Working with vehicle diagnostic ports and telematics devices comes with certain important warnings:
- Harness Compatibility is Critical: Using non-approved harnesses can lead to serious safety risks, including fire, and potential damage to the vehicle’s electrical system. Always use Geotab-approved harnesses or those recommended by your telematics device provider, acquired from authorized channels.
- Professional Installation is Recommended: Unless you have experience with vehicle electrical systems and telematics device installation, professional installation is strongly encouraged. Incorrect installation can lead to device malfunction, vehicle issues, or even safety hazards.
- CARB Compliance (California): If your Kenworth truck operates in California, be aware of CARB (California Air Resources Board) regulations. For certain programs like the Clean Truck Check (CTC), specific connector types might be required or restricted. Always ensure compliance with local regulations when installing telematics devices, especially in California.
Conclusion
Locating the OBD2 port on a 2016 Kenworth is usually straightforward, typically found under the dashboard on the driver’s side. Understanding its purpose and the correct procedures for using it, especially for telematics device installation, is essential for Kenworth owners and technicians. Always prioritize safety, verify harness compatibility, and consider professional installation to ensure a smooth and effective connection to your 2016 Kenworth’s diagnostic system. For further assistance or specific harness recommendations, consult official Geotab documentation or contact a certified Kenworth service professional.
