I thought Toyota took a huge amount of backlash for trying this bullshit and dropped the subscription service for features installed in your car.

Give it time, someone will see the money in “jail breaking” these features from your vehicle.

The most difficult? Unplugging all the various sensors and wiring harnesses.

Typically if a check engine light comes on shortly after fueling up, it’s likely the fuel cap isn’t on properly.

Yeah, if you have the Toyota app you should be able to unlock the 4wd feature. It’s a monthly subscription service, but you can probably just pay for it during months of heavy snow fall.

Sorry, this is sadly a joke. Converting a vehicle from 2wd to 4wd, although technically possible, it’s not practical AT ALL. I’d suggest selling the vehicle and buying one that fits your needs.

The $400 one can probably do more complex things, like crankshaft/camshaft position sensor re-learn, etc… it will also be able to show data the simple scanner can’t access. Things like fuel trim, a/f ratios, engine temp, trans temp, misfire counts and hundreds more. If you just need codes read, $40 one is fine. If you want to actually diagnose problems, $400 one is needed.
