Helps with most things – BlueDriver OBD2 Scan Tool Review

I've used this on a 2006 Sienna and 2006 Frontier and it's helped me diagnose and fix failed O2 sensors, and failed injection coils. Wasn't able to diagnose anything related to the A/C system, but you can't beat it for the combustion system. Saved me many diagnosis fees and related fixes when I'm up for doing the work myself.
