Tool Review: Snap-on TRITON-D10 Integrated Diagnostic System

The Snap-on TRITON-D10 scan and scope tool is ideal for shop owners and general technicians that need scope functionality, intuitive diagnostic testing, and system verification from a single source for more all-around certainty, even on complex repairs.

The tool allows technicians to dig deep into vehicle systems and evaluate performance with comparative data. In doing this, it helps to streamline the diagnostic process.

Additionally, the tool features rugged hardware designed specifically for the shop, fast two-second boot-up, and a 10" capacitive touchscreen display.

Scan tools are an integral part of diagnosing vehicle issues. They often provide crucial data as well as any trouble codes to help technicians resolve potential vehicular malfunctions.

Tool reviewer Mike Reynolds, diagnostic technician at Mobile Automotive Service Solutions (MASS) in Charleston, South Carolina, was impressed with how the Snap-on TRITON-D10 scan and scope tool aided him with quick diagnostic checks.

"I generally use the TRITON for any diagnostics that I know will be quick or [will] need one or two scope channels for," Reynolds says. He often opts for this tool to help diagnose module communication faults.

"With the TRITON and a few scope leads, I am able to verify that the module is not communicating with the scan tool, then measure power and ground to the module with the incorporated multimeter, [and finally] scope the communication circuits to verify that I have a healthy communication circuit,” he says.

Reynolds is a “big fan” of the “simple” two-channel scope that comes with the TRITON. He appreciates that it’s available when needed, but not “cumbersome” otherwise. He also finds the touchscreen useful, which he says is "big enough" to justify the TRITON as an everyday tool.

The TRITON is big on efficiency as a whole, with a quick and easy start-up sequence. Once it’s up and running, it stays powered up through an included data link connector (DLC) cable that helps keep its internal battery charged.

"I don't think I've used the AC charger other than when installing updates," Reynolds says.  

Despite not coming with any instructions, the TRITON was "as user-friendly as its predecessors.” Setup was similarly easy, with a few routine prompts that lead to an otherwise “plug and play” installation.

Editor's note: Reynolds received a pre-production unit of Snap-on's TRITON-D10, which did not come with instructions. However, all units come with a quick start guide and a full user manual, and training is available online. 

Reynolds would be hard-pressed to think of meaningful ways to improve the TRITON. He does want to see the ability to print directly from the unit added eventually, as he prefers interfaces that allow this.

Overall, this technician believes Snap-on’s TRITON-D10 is an efficient, easy-to-use, everyday tool. 

"It's my go-to aftermarket tool for most of our diagnostics until we need a few extra scope channels, or to watch as many data PIDs as possible at one time."
