What Is The Best Scan Tool For Heavy-Duty Trucks?

One of the most important pieces of equipment for our team, both in the shop and out in the field, is the scan tool. The on-board diagnostics or OBD system is the truck’s ability to self-diagnose and report. It informs the driver of problems through dashboard alerts, but these are often just general messages. Scan tools help the mechanic pinpoint the exact problem.

But we can’t just plug in the same tool an auto mechanic would use. Heavy-duty trucks have bigger, more complex engines, and thus they need the right scan tool to meet their diagnostic needs.

 

What Does A Scan Tool Do?

Almost every vehicle is now equipped with truck and trailer diagnostic ports. These are also known as OBD ports, and they allow mechanics to run OEM vehicle diagnostics on all truck models through access to data from the engine control unit. An auto-scanning OBD device is used to receive data codes along with other info regarding the car’s general health.

The scan tool gives us access to the braking systems, airbags, powertrain data, transmission, body and chassis controllers, as well as the instrument cluster, no matter where you need it. The Patrick’s Mobile team stays on top of all the latest vehicle diagnostic applications and regularly runs updates to stay on top of the rapidly changing technology.
