Can Any Scanner Be Used on a Dodge Cummins?

All scanners will not work for your vehicles. This is because all scan tools are not compatible with your automobile. 

You need to check the compatibility of the device with your vehicle’s manufacturer and model before investing in a scan tool. When it comes to diesel vehicles or trucks in general, you need to be extra careful, as many scan tools are not compatible with their format. 

What to Look for in a Scan Tool

There is no exaggeration in saying the market is experiencing an abundance of scan tools. But are all of those worth your time and money? What makes a good scan tool? Your questions have been answered! Here are the features to look for in a scan tool:


Oftentimes, the device you buy comes with its own app, whereas some devices work on third-party apps. These will allow you to monitor the live data streams and different features from the convenience of your smartphone. They are very important to have and it better to opt for a device whose app has a good user interface. 


A warrantied product is more durable and reliable than one without a warranty. Thus, make sure the product you plan on buying has an extended warranty. 

Software Updates

The software of your scan tool should remain up-to-date. Thus, invest in a product that has frequent and useful software updates. This is important, as if you get a new vehicle, your scan tool should be able to diagnose it, as well. Furthermore, updates prevent the software from lagging and keep it operating smoothly so it can continue to diagnose systems efficiently.
