1

Plug the J2534 cable into the vehicle's OBD-II port (under the dash, driver's side).

2

Plug the cable's USB end into your PC.

3

Turn the ignition to ON, engine OFF (this is called KOEO). Many scans are only allowed with the engine off so no modules are missed.

1

Click 🔌 Connect at the top of the window.

2

The status changes to Connected, and a banner shows the decoded year, engine, and mileage.

3

If it can't connect, check the cable, the ignition position, and that no other diagnostic program is using the device.

1

Open Vehicle Health Scan from the home screen.

2

Click Quick Scan. The tool contacts every module and lists its fault codes.

3

Faults are color-coded — see Fault Statuses.

1

Read each fault's plain-English description and what you might notice.

2

Fix the underlying cause where needed (some faults won't clear while the problem is still present).

3

Use Clear to erase codes. For engine/transmission codes that won't clear, the tool guides you through a key-cycle and re-checks automatically.

1

From the Health Scan, choose Save PDF report.

2

The report includes a decoded-VIN summary, the color-coded faults, and a legend explaining each status.
