Connect vehicle
Pair once. After the serial link opens, Connect initializes the adapter and automatically runs every enabled capture stage: VIN, mileage, stored/pending/permanent generic DTCs, freeze frame, Mode 06, ECU identity, read-only module discovery, CAN survey, and local save.
Connect it. We collect the rest.
The primary workflow is automatic. Manual controls stay available below for engineering and troubleshooting.
AUTOMATED WORKFLOW
Capture status
Manual / engineering controls
These controls are optional. The normal workflow runs automatically after Connect. Full Capture never clears codes or performs bidirectional controls. Enhanced OEM module DTC reads will join the same automatic workflow as each manufacturer pack is validated.

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
Run a scan. If the vehicle reports a freeze-frame trigger DTC, Connect captures common frozen PIDs automatically.
MODE 06
Misfire monitor
Full Capture automatically discovers standardized monitor IDs and queries supported misfire monitors.
ENHANCED DISCOVERY
Module discovery
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.
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
Full Capture records a bounded sample of active CAN traffic without transmitting diagnostic requests during the survey.

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.
