ATD is not a high-volume repair counter. Projects are evaluated individually, with an agreed scope, careful methods and transparent findings.
Diagnostic disciplineObserve, isolate and test the actual system.
Detailed vehicle careFinish quality comes from close inspection.
Thoughtful presentationCareful condition work at every level.Conceptual brand imagery only. The settings shown are not presented as ATD premises or customer properties.
Symptom analysis, OBD-II data interpretation, sensor plausibility, electrical checks, ground and circuit testing, and investigation of intermittent behavior.
A preliminary scan is not a complete diagnosis. Scope and equipment availability are confirmed before work.
Careful detailing, cleaning and vehicle-condition attention with an emphasis on visible workmanship and practical preservation.
Specific correction methods, products and availability depend on the vehicle and condition.
Independent observations of visible condition, available records and appropriate diagnostic data to support a more informed purchase or repair conversation.
Not a guarantee that every hidden defect will be found.
For investigative work, ATD organizes the question, photographs, diagnostic data, tests, relevant repair history, verified findings, competing explanations and a practical next step into a packet the vehicle owner can retain or give to another technician.
Reports reflect evidence actually reviewed and do not automatically establish liability or repair necessity.
I don't bill by the hour. We first agree on the question being investigated, the methods that make sense and the expected deliverable. Then we agree on terms for that specific assignment.
Because ATD is selective, availability and acceptance are never automatic. Some work is better handled by a specialist, and I will say so when that is the responsible recommendation.
Contents match the nature of the engagement. Documentation is not proof of a repair, warranty or guaranteed fault resolution.
ATD is developing fleet inspection records and publishes technical training resources. These are separate from an ordinary consumer service appointment.
An ATD-style review separates verified observations, competing explanations and the next discriminating test. It should not dress an untested theory up as a confirmed failure.
