Black Hills Mobile Diagnostics comes to you with advanced scan tools, OEM-level data, and 11+ years of ASE Master experience. Stop guessing, stop throwing parts, and get to the root cause of drivability and electrical issues.
On-site diagnostics for shops, fleets, and vehicle owners.
Whether you are a repair shop that needs advanced diagnostic backup, a fleet manager trying to keep vehicles on the road, or a vehicle owner with a stubborn issue, Black Hills Mobile Diagnostics brings the lab-grade testing to you.
Advanced drivability diagnostics
Check engine lights, intermittent misfires, no-starts, rough runs, fuel & air issues, and more — verified with data, not guesses.
Electrical & network (CAN) issues
Parasitic draws, module communication faults, intermittent power/ground, network problems, and wiring faults traced and documented.
Pre-repair testing & second opinions
Save money and time by confirming the actual failed component before parts are ordered. Great for fleets and busy shops.
Fleet diagnostics that keep your vehicles working, not waiting.
Work trucks, vans, and service vehicles are only making money when they are moving. We come on-site to your yard or shop to diagnose issues quickly and provide a clear plan so your team can complete repairs with confidence.
Stop the parts cannon. Start fixing the real problem.
Too many vehicles get parts thrown at them. Black Hills Mobile Diagnostics focuses on root-cause testing: voltage drop, pressure, scope patterns, bidirectional controls, OEM scan data, and more.
