I keep coming back to this topic as i have yet to find a working solution for my project, this is more personal ability to gather the information and depending on how accurate and trustworthy it is, use it to keep maintenance history on the truck.
Back before 2017 i had some "Cypress" OBD boards that i was working with, then Hurricane Harvey happened and lost all my electronics, so started looking at the adafruit OBD cable and sparkfun can bus boards but no matter what i could never get actual data out of my truck.
All i want to try and accomplish is polling my truck for basic information, miles, oil change %, tire pressure and maybe even some CIL errors if any ever occur.
Ultimately id like to be able to have it setup with a wireless board that can transmit or be pinged to get the data once I'm home in the driveway.
Can anyone offer suggestions on boards, cables or examples on how i can get this out of a 2017 Silverado? Im not asking for a full working solution, although that would be nice, as long as i can successfully poll the truck and get any valid data back, would be a perfect starting point.
