Compare Cando vs OTR Diagnostics

Company Focus: Trucking Is Our Priority - Not a Product Category

When it comes to choosing a diagnostic tool, the company behind the product matters just as much as the tool itself. Not every brand is built with the same focus and that difference shows up in the way the tool performs when it matters most.

CanDo Diagnostics

CanDo was originally launched as a division of a large automotive aftermarket manufacturer, producing private-label diagnostic tools for retailers like NAPA and AutoZone.

As demand grew, so did their catalog expanding into diagnostics for passenger vehicles, motorcycles, powersports, and marine equipment, with commercial truck diagnostics becoming just one slice of a much broader offering.

Their development and production span multiple global regions, and while they do serve the heavy-duty market, it's clear that trucks are just one of many priorities.

OTR Diagnostics

At OTR, we don’t split our focus. We don’t make tools for cars, boats, or motorcycles. We build diagnostic tools for heavy-duty diesel trucks and only trucks.

That singular focus is why OTR Diagnostics works so well for drivers, owner-operators, and small fleets. Our tools are:

• Purpose-built for real-world truck problems

• Designed and supported in the United States

• Continuously updated to handle new fault codes, regen issues, and emission system changes

• Backed by a team that actually understands diesel diagnostics because it’s the only thing we do

This isn’t just a product line for us. It’s a mission.

So, whether you're battling a persistent fault code, trying to avoid a costly regen cycle, or just want to avoid the downtime and hassle of dealership visits, you deserve a tool built specifically for the road you run.

Choose a tool that’s built for only trucks, not everything else.

If you’re ready to take control of your truck’s diagnostics without the complexity or compromises, it’s time to look into OTR.
