Plug in a compatible ELM327 OBD2 adapter while parked. Scan codes, save the record, and bring it to a mechanic.
P0420 · reported through standard generic OBD2
Axlyne preserves the generic code, reported status, scan time, and selected vehicle. It does not convert those facts into severity or driving advice.
Connect a compatible ELM327 OBD2 adapter. Follow the adapter and phone prompts while the vehicle is safely parked.
Tap Scan while parked. Axlyne reads supported generic trouble codes reported by the car. Coverage varies by vehicle and adapter.
Save the code, reported status, scan time, and car. Share the record with a qualified mechanic. Axlyne does not diagnose faults.
Start and stop foreground GPS recording yourself, or enter mileage manually. Choose a business or personal label and export PDF and CSV records. Axlyne does not determine tax eligibility.
After Axlyne verifies that the connected vehicle VIN matches the selected vehicle, Drive and HUD show supported standard Mode 01 values on your phone. Switch speed between MPH and KM/H. Axlyne sends no control commands and does not save live samples. Car displays use saved status only; live gauges stay in the phone app.
Vehicle profiles keep service history, expenses, and scan records tied to the selected vehicle. Unlimited vehicles on Pro.
Axlyne AI reads the scan you already saved and answers in plain language. It cites the saved record fields it uses and prepares questions worth asking a qualified technician. It does not diagnose the fault.
Requires sign-in, Pro, a saved vehicle, internet access, and current service availability.

Sample report

View sample report (PDF)Demonstration data. No physical vehicle was scanned. The report records generic OBD observations and does not diagnose a fault, recommend a repair, or establish road safety. The sample PDF is in English.
Compatibility
Axlyne uses the standard ELM327 protocol. A working connection depends on the vehicle protocol, the connection method supported by the phone and adapter, and the data the vehicle exposes.
Apple restricts Bluetooth Classic to MFi hardware, so on iPhone you'll need a BLE (Bluetooth Low Energy) or Wi-Fi OBD2 adapter.
Android can also use Bluetooth Classic when the phone, adapter, and vehicle connection support it, alongside BLE and Wi-Fi.
Those model-year rules generally indicate an OBD2 port, not guaranteed compatibility. Connection and available data depend on the vehicle, adapter, phone, and what each control unit exposes. Axlyne records only supported standard responses observed during the current scan.
Current local prices appear in the app store before purchase. Subscriptions auto-renew until canceled in the store where purchased. Cancellation timing follows that store's terms.
