UNIVERSAL VEHICLE CAPTURE

One tap. One complete session.

Read-only engineering capture, automatic local saving, and replay-ready raw data for every vehicle you scan.

Close the OBDLink app before connecting. Keep the vehicle parked for the engineering capture. Full Capture never clears codes or performs bidirectional controls.

Tap a code for its definition and captured freeze-frame values. Generic clearing remains a separate protected action and is never part of Full Capture.

MODE 02

Freeze frame

Automatic

Run a scan. If the vehicle reports a freeze-frame trigger DTC, Connect captures common frozen PIDs automatically.

MODE 06

Misfire monitor

Read-only

Full Capture automatically discovers standardized monitor IDs and queries supported misfire monitors.

Not scanned

ENHANCED DISCOVERY

Module discovery

Read-only presence probes

Full Capture uses only validated read-only discovery profiles. GM GMLAN discovery is enabled first; unsupported makes remain passive-only until a verified profile is added.

Not scanned

A discovered diagnostic node is not assigned a module name unless evidence supports the identity. Unknown responders are intentionally preserved for later analysis.

NETWORK

Passive CAN survey

Receive-only

Full Capture records a bounded sample of active CAN traffic without transmitting diagnostic requests during the survey.

Not surveyed

Run a basic scan to interrogate each standard OBD responder individually.

DATA POLICY FOR THE LAB

Local by default

Vehicle captures are saved in this browser/device. Connect Lab does not automatically upload customer or vehicle data to FlowWrench servers. Export is an explicit action. Use capture and diagnostic functions only on vehicles you are authorized to service.
