# AutoIQ — FAQ

> Frequently asked questions about AutoIQ OBD-II desktop diagnostics.

## General

<AccordionGroup>
  <Accordion title="What is AutoIQ?">
    AutoIQ is an OBD-II desktop application for Windows. You connect a supported USB OBD-II adapter to your vehicle and use AutoIQ to read live data, PIDs, and freeze frames. Mac support is planned for later.
  </Accordion>

  <Accordion title="Which platforms are supported?">
    Windows (64-bit `.exe`) only today. macOS is planned for a future release.
  </Accordion>

  <Accordion title="Do I need a special adapter?">
    You need a supported OBD-II USB adapter (ELM327-style or J2534). Bluetooth and Wi‑Fi adapters are not supported in the current desktop app. See [Supported adapters](/autoiq/adapters).
  </Accordion>

## Connection & data

<AccordionGroup>
  <Accordion title="What are PIDs and freeze frames?">
    **PIDs** (Parameter IDs) are live sensor and ECU values (e.g. RPM, coolant temp). **Freeze frame** data is a snapshot stored by the ECU when a DTC was set; it helps diagnose intermittent issues.
  </Accordion>

  <Accordion title="Why doesn’t my adapter connect?">
    Ensure the adapter driver is installed, the ignition is ON, and you selected the correct COM port in AutoIQ. See [Supported adapters](/autoiq/adapters) and [Install on Windows](/autoiq/install-windows) for driver and signing issues.
