Review on 🚗 Innova 3150RS OBD2 Scanner / Car Code Reader with ABS, SRS, Real-time Data, and Service Light Reset by Jake Powell

Eliminates low voltage MIL right out of the box. We left the keys in the car and the battery was dead. I checked the battery and alternator and everything is fine! MIL didn't come back. You can also plot the PID which is very helpful. Once you've selected the PID you want to monitor, simply press the back button on the device and it will switch to real-time graph display mode. Press return again and it will switch back to live numeric data. Great device, I should have bought it sooner!
