Brian,
Thanks for adding to the mix. Thats exactly why I mentioned, Where are we at? If the dealership can access my car remotely and send me advisories messages, why can't I access it from my phone or home computer. I just hate buying something that is outdated when it leaves the manufacturer. Some systems can't be read on some scanners, Airbags/ tire pressures, ABS, but that information is in the details or the buyers reviews.
iPhone apps, I'll look into a required ELM 327 OBD II wi-fi scanner or other Bluetooth adapters.
BDA, Like you that's mainly what I use it for. I have and older model Autel OBD2 scan tool that reads many dtc codes but now my daughters 2017 honda wont even let it scan. 2012 Sonata Hybrid and a 2000 hyundai Tiberon works perfectly and then I google the necessary culprit. It only tells me latched faults not any details. Imagine, the computer knows the status, open-closed, on-off,/temp/etc, but won't tell me.. the owner but sends it digitally to the dealer. I know I'm just ranting a bit . I see some let you play with airfuel mixtures when driving and other really cool features. so my search will continue.
Thanks Turbo
