This is very helpful. I just took my 2022 Sienna in for the 1st 5k mile service (oil change and tire rotation) and noticed a decreased miles per gallon, the engine runs more often at low speeds instead of the motor. Could the dealer have possibly done a recalibrate using this Techstream or maybe just the oil change and tire rotation affected the mpg.

If you make same video for all cars so it will be a reference to you and to all people in the world
What could be the posible problem when active data test is not working on one car but work on orther cars
I don’t know but it could be the software/ecu on the car or different yr model.
How do you setup the Techstream and what cable you use? Where are you located?
Is there oil service?
Not sure about newer ones but most can be reset manually. Each yr has its procedure which u can google.
