Understand the relationships
ARIA connects monitor results, operating conditions and parameter behavior.
Compare monitor history, connect live parameters and investigate captured conditions with ARIA. Continue the conversation in your browser and turn the findings into a shop-branded report.
Ask ARIA what changed, how the readings fit together and what deserves a closer look. Explore Mode 6, live parameters, Freeze Frame and your vehicle’s history.

Real analysis from recorded vehicle sessions.
ARIA connects monitor results, operating conditions and parameter behavior.
Compare sessions and check the distance from the ECU’s reported limits.
Keep the analysis with the vehicle and share a clear report.
In this recorded example, ARIA compares 0.583 V with 0.132 V against a 0.050 V minimum. She explains the remaining margin and why a single monitor snapshot does not establish deterioration.
ARIA considers coolant temperature, load, manifold pressure, throttle and fuel trims together. The explanation ties the measurements to the vehicle’s operating state.
ARIA compares monitor trends with past fuel trims and drive-cycle context. In this example, she identifies a catalyst ratio worth watching while explaining that it remains below the failure threshold.
Continue the analysis with interactive ARIA Web Chat, choose the source session and turn the findings into an editable, shop-branded report with repair and maintenance context.
See the vehicle at the moment the fault set, then check the monitor evidence manufacturers use to judge component performance.
Selectable parameter graphs, six fixed dashboard gauges, emissions readiness and complete parameter coverage—presented as the actual product, not caption art.
The OBD BLE GEN2 adapter connects the vehicle to OBDAI and enables SAE J1979-2 support. It arrives protected in its own case.
