An AI diagnostician. Working your scan tool.
OBDAI puts an AI diagnostician in control of your scan tool. Describe the symptom. ARIA chooses what to read, gathers the evidence, and works through the problem with you—from the first live reading to the next test and the customer report.
ARIA works the scan tool herself—choosing sensors, collecting live readings, and investigating what’s wrong. She checks back on a timer or wakes when a value changes, examines exactly what happened during the drive, and researches the next test. Talk to her. Show her a photo. She connects the evidence, remembers the vehicle, and turns the findings into a report you can use.
01
Tell her what the car is doing by voice or text. Show her a connector, leak or meter reading. ARIA chooses the sensors that matter, configures their collection, and builds the investigation around the problem you brought her.
02
ARIA pulls fresh readings, trouble codes and freeze frames, examines the computers’ own monitor tests against their limits, and checks readiness and since-clear history. She brings the evidence together to work out what to test next.
03
“I’ll check again in five minutes.” Or: “I’ll wake up when that value changes.” ARIA sets scheduled check-ins and condition-triggered watches, then returns to the investigation when the time or event arrives. You don’t have to stare at a graph.
04
Ask what happened when the car stumbled. ARIA examines the recorded readings around that moment. When deeper research is needed, she offers to find and read service information—pinouts, specifications and diagnostic procedures—and connects it with your vehicle’s data.
05
The next visit starts with previous readings, inspections and conversations. ARIA can compare tests across drives, revisit earlier findings, and examine what changed after a repair. Keep investigating in the app, or continue with ARIA on the web with PRO.
06
Get a clear explanation of the findings and the next checks to make, then a shareable diagnostic report. PRO adds shop-branded customer documents, repair estimates and maintenance recommendations—so the work in the bay carries through to the customer.
