- ✅ Retrieve codes before planning your next check — A compatible app can read available engine fault codes through the adapter.
- ✅ Watch useful data during a stationary test — Available live parameters appear in the connected diagnostic app.
- ✅ Check readiness before arranging emissions testing — Supported software can retrieve the vehicle's available readiness information.
- ✅ Keep a compact interface in your tool bag — The small plug-in body needs no separate handheld display.
- ✅ Choose a quantity for your workspace — Packs contain one, two, three or five blue adapters.
Turn available engine data into a useful starting point
Plug the adapter into a compatible OBD-II port, pair its Bluetooth connection with a suitable device and select the matching connection within your diagnostic app. The photographs demonstrate Android pairing. Confirm your exact phone, app and vehicle compatibility before ordering; a Wi-Fi connection or iPhone compatibility is not guaranteed for this selected blue Bluetooth version.
Available functions include engine-code reading and clearing, live sensor data, freeze-frame information and emissions readiness where the vehicle and app provide them. ABS and airbag/SRS diagnostics are excluded. A code reports a condition and does not by itself identify a failed component.
Record codes before clearing them, since clearing does not repair the cause and can reset readiness status. Choose the pack quantity needed. Diagnostic software, any required licence and the phone are not included as confirmed package contents.
