Before jumping into the reset process, it’s important to understand what the check engine light actually means. The engine light—also known as the malfunction indicator lamp (MIL)—is part of your truck’s onboard diagnostics (OBD) system. When the engine control unit (ECU) detects a problem with the engine, emissions system, or related components, it triggers the light to alert you.
On a 2013 International Prostar, this system is highly advanced and monitors everything from fuel injection and exhaust gas recirculation (EGR) to turbocharger performance and diesel particulate filter (DPF) status. The light can come on for minor issues like a loose gas cap or serious problems like a failing sensor or engine misfire.
Important: Never ignore the check engine light. Even if the truck seems to be running fine, underlying issues can worsen over time and lead to costly repairs or breakdowns.
The light may appear in different colors or flash patterns:
– Solid yellow or amber: Indicates a moderate issue that should be checked soon.
– Flashing or red: Signals a severe problem, such as a misfire that could damage the catalytic converter. Pull over safely and seek immediate assistance.
Resetting the light without addressing the root cause is like turning off a smoke alarm while the fire still burns. Always diagnose and fix the problem first.
Tools You’ll Need to Reset the Engine Light
To reset the engine light on a 2013 International Prostar, you’ll need the right tools. Unlike some passenger vehicles, heavy-duty trucks like the Prostar often require professional-grade diagnostic equipment to access and clear fault codes.
Here’s what you’ll need:
1. Compatible Scan Tool
The most reliable way to reset the engine light is by using a scan tool that can communicate with the truck’s J1939 or OBD-II system. Recommended options include:
– International® ServiceMaxx: The official diagnostic tool for International trucks. It provides full access to engine, transmission, and aftertreatment systems.

– Heavy-duty OBD-II scanners: Devices like the Autel MaxiCOM MK908P or Snap-On Zeus can read and clear codes on International trucks.
Avoid using basic consumer-grade OBD-II scanners designed for cars. They often lack the capability to access heavy-duty systems and may not clear all codes.
2. Laptop or Tablet (if using software-based tools)
Some diagnostic tools require a laptop or tablet to run the software. Make sure your device meets the system requirements and has a stable connection (USB or Bluetooth).
3. OBD-II Cable or Wireless Adapter
Depending on your scan tool, you may need a physical cable to connect to the diagnostic port or a wireless adapter for Bluetooth connectivity.
4. Owner’s Manual or Service Guide
Keep your truck’s service manual handy for reference. It can help you locate the diagnostic port, understand error codes, and follow manufacturer-recommended procedures.
5. Basic Hand Tools (Optional)
In some cases, you may need a screwdriver or panel removal tool to access the OBD-II port, especially if it’s behind a cover or under the dashboard.
Locating the OBD-II Diagnostic Port
The OBD-II port is the gateway to your truck’s diagnostic system. On a 2013 International Prostar, this port is typically located in one of several common locations. Knowing where to find it will save you time and frustration.
Common Locations:
– Under the dashboard, near the driver’s seat: This is the most common spot. Look just below the steering column, often within arm’s reach.
– Center console area: Some Prostar models have the port mounted on the center console, near the gear shifter or HVAC controls.
– Behind a removable panel: In certain configurations, the OBD-II port is hidden behind a plastic panel on the lower dashboard or kick panel. You may need to gently pry it open.
– Inside the glove compartment: Rare, but possible. Check the back wall of the glove box.
The port is a 16-pin connector, usually black or gray, with a trapezoidal shape. It may have a small cover or cap labeled “OBD” or “DIAG.”
Tip: If you can’t find the port, consult your owner’s manual or search online using your truck’s VIN for a wiring diagram.
Step-by-Step Guide to Reset the Engine Light
Now that you understand the basics and have your tools ready, let’s go through the step-by-step process to reset the engine light on your 2013 International Prostar.
Step 1: Ensure the Problem Is Fixed
Before resetting the light, confirm that the underlying issue has been resolved. For example:
– If the light came on due to a loose fuel cap, tighten it securely.
– If a sensor was faulty, replace it.
– If there was a DPF regeneration issue, ensure the filter was cleaned or regenerated.
Resetting the light without fixing the problem will only cause it to come back—sometimes immediately.
Step 2: Turn Off the Ignition
Make sure the truck is parked, the parking brake is engaged, and the ignition is turned off. This prevents any electrical issues during the diagnostic process.
Step 3: Connect the Scan Tool
Plug your scan tool into the OBD-II port. If using a wired tool, connect the cable securely. For wireless tools, ensure Bluetooth is enabled and paired with your device.
Step 4: Turn the Ignition to “On” (Do Not Start the Engine)
Turn the key to the “ON” position. The dashboard lights should illuminate, but the engine should remain off. This powers up the ECU and allows the scan tool to communicate with the truck’s systems.
Step 5: Power On the Scan Tool
Turn on your scan tool or launch the diagnostic software on your laptop. Wait for it to initialize and detect the vehicle.
Step 6: Select the Vehicle and System
Follow the on-screen prompts to select:
– Vehicle make: International
– Model: Prostar
– Year: 2013
– Engine type (e.g., MaxxForce 13, 15)
Some tools will automatically detect this information.
Step 7: Access the Diagnostic Menu
Navigate to the “Diagnostics” or “Troubleshooting” section. Look for options like:
– “Read Fault Codes”
– “View Active DTCs” (Diagnostic Trouble Codes)
– “Engine Control Module”
Step 8: Read and Record the Fault Codes
The scan tool will display any active or stored fault codes. These codes (e.g., P0401, SPN 5246) help identify the specific issue. Write them down or take a screenshot for reference.
Even if you’ve already fixed the problem, reviewing the codes confirms what triggered the light.
Step 9: Clear the Fault Codes
Once you’ve reviewed the codes, look for an option like:
– “Clear Codes”
– “Erase DTCs”
– “Reset MIL”
Select this option. The tool will send a command to the ECU to clear all stored fault codes and turn off the check engine light.
Note: Some systems may require you to confirm the reset or enter a security code. Follow the on-screen instructions carefully.
Step 10: Verify the Reset
After clearing the codes:
– Turn the ignition off.
– Wait 10–15 seconds.
– Turn the ignition back to “ON.”
Check the dashboard. The check engine light should no longer be illuminated. If it’s still on, the reset may not have been successful, or a new issue may have been detected.
Step 11: Perform a Test Drive
Start the engine and take the truck for a short drive under normal conditions. This allows the ECU to run self-checks and confirm that all systems are functioning properly.
Monitor the dashboard during and after the drive. If the light stays off, the reset was successful.
