Review on 🚗 NEXAS OBD2 Scanner Code Reader with Bluetooth 5.0 for iPhone Android Windows - Diagnostic Scan Tool for Cars and Motorcycles, Check Engine Light Scanner for Vehicles by John Brouillard

This device connects to your vehicle's OBD connector. It emits a WiFi signal that you can connect your phone or tablet to via the app. I am using the OBD Fusion app, it connects quickly when the device is powered on. I use it in my camper. After I reconnect the chassis battery to the RV, the check engine light usually comes on. This device will display an error code and can reset the check engine light. It also provides an up-to-date display of engine values. This includes a mileage estimate. I mounted an old iPhone on the dash so I can view real-time engine information. I recommend the OBD Fusion app and this device.
