How to Select a Truck Scan

When a truck or heavy-duty vehicle is having an issue, it’s important that the right tools are used to find the problem and then fix it. Using the wrong tool can result in expensive repairs and a lot of guesswork on the mechanic’s part. A truck scan helps to take the guesswork out of finding the root cause of a problem. This article takes a closer look at the different types of truck scans available on the market and what to consider when selecting one.

A Code Reader Is a Basic Plug-and-Play Tool

A code reader is a basic plug-and-play truck diagnostics tool that reads and displays fault codes. They aren’t nearly as accurate or as detailed as scan tools and offer far less functionality.

Some code readers only read engine and emissions-related trouble codes, while others can also scan a variety of other issues, including problems with the transmission, drivetrain, and braking system. In addition to reading and clearing codes, they may also be able to tell you the location of the problem and provide you with detailed information about what’s wrong with your truck.

If you’re looking for a value-packed truck scan, then it’s important that you look at the features that come with each option. A good option is a dual-channel scanner that can scan OBD1 and OBD2 systems as well as J1587 and J1708 data links. This means it can work with a wide range of vehicles that are on the road today.

It’s also helpful to find out if the scan tool you’re considering has additional functions such as freeze frame and readiness monitor updates. This can help you save time by letting you know what’s going on with your truck in real-time.

Some truck scan tools can even help you troubleshoot and repair ghost codes. These are a type of error that doesn’t actually trigger a check engine light but can be difficult to diagnose without the proper tools. The best way to identify a ghost code is to use an advanced HD truck scan tool that can read more error messages from your truck’s ECU. These types of scan tools can be more costly than a basic OBD-based model, but they’re worth the investment if you’re looking for a full-featured diagnostics tool.

The Benefits of a High-End Truck Scanner

Unlike light duty automotive scanners, heavy-duty scan tools aren’t always updated on a regular basis. However, this is starting to change as the need for better, more reliable diagnostics continues to grow in the industry. Luckily, most manufacturers now offer weekly or more frequent updates for their heavy-duty scanners.

For many mechanics, a high-end truck scan tool is worth the cost. This type of device can be a lifesaver when diagnosing problems, especially for truckers who need to get back on the road as quickly as possible. With a high-end diagnostic laptop, they can receive a detailed rundown of their truck’s issues, making it easier to figure out what’s wrong and how to fix it.
