❓ Frequently Asked Questions
Which OBD adapters are compatible?
OBD Scan Pro works with ELM327-based adapters connected via WiFi or Bluetooth Low
Energy (BLE). Classic Bluetooth adapters are NOT supported on iOS.
Why can't I see any data?
Make sure the engine is running (not just ignition). Some vehicles require the engine
to be on for sensor data. Also verify the adapter is properly plugged into the OBD-II port.
What cars are supported?
All vehicles manufactured after 1996 (OBD-II compliant) are supported. This includes
most gasoline, diesel, and hybrid vehicles sold worldwide.
