OBD2 Scanner

Plug an inexpensive Bluetooth ELM327 adapter into the OBD2 port under the steering wheel — AI-MASTER finds it, reads fault codes and the VIN, and AI diagnostics explains what they mean, how much the repair costs and which parts you need. Clear the codes and the Check Engine light goes out. The VIN goes straight into the car card. Your first scan is free on any plan, unlimited on PRO and STO. Android: Bluetooth and BLE adapters; iPhone: BLE adapters (Bluetooth 4.0).
