Built by a Tech — Not a Marketer
I’m Dave Caron, and after 20+ years in the shop and on the road, from diagnosing motorcycles to managing teams, I realized that the biggest problems weren’t the tools… they were the missing processes.
That’s why I created this checklist. To give you a repeatable, trackable diagnostic path that can work across every department in your operation.
And best of all, it’s free to start using today. No Money, No friction. Just a better way to run diagnostics.
Why This Checklist Matters:
If you're responsible for keeping a fleet of vehicles running, whether that’s public works trucks, emergency response units, or heavy construction equipment, you know the cost of inconsistent diagnostics.
Technicians skip steps. Repairs get rushed. And by the time the vehicle comes back with the same issue? You've lost time, credibility, and maybe compliance footing too.
That’s why this Professional Diagnostic Workflow Checklist was built, not by a software company, but by a career tech and shop owner who’s seen firsthand how poor diagnostic workflows cost shops thousands in rework and wasted hours.
What's Inside the Checklist?
This isn’t a fluff-filled PDF with a few generic tips. This is a technician-built, fleet-ready diagnostic framework designed for real-world use in shops that service:
Diesel
Automotive
Construction & Off-Highway
Agricultural
Marine
Powersports & Motorcycles
Diagflow Dashboard
Who This Is For
This checklist was made for:
Fleet Managers who need visibility into what their techs are actually doing
Shop Owners tired of rework and repeat visits
Lead Techs who want a clear, no-BS process their team can follow
Department Heads who need documentation for DOT audits or budget meetings
If your team is still relying on memory, mixed tools, or guesswork… this is the system you've been missing.
