good lord. i'm so glad my toyota doesn't have any of those features. shout out to the lean method.

If it is anything after about 2012 it probably does. Also if this hack is out of the software I think it is, I am not surprised. Some of the main devs were more worried about what a function was named than how to make it work correctly and securely.

  • Depends on where the data comes from.

    A bunch of Toyotas have a telemetry module (basically an LTE modem tied into the can bus and the head unit), but the introduction date varies.

    Tacomas for example didn’t have it until 2020.

    I’m not sure though if this data is/was getting pushed through that or something else.

  • how do i know if it's enabled? i've never done any sort connectivity thing in my vehicle.

    • LTE/3G/CDMA modem hanging off the can bus usually with some sort of controller. You do not have to enable it. The original use was to track vehicles during the loan pay off and remote shut them off for lack of payment. This includes GPS and other telemetry. They then added the 'buy wifi' package that talked to that. They basically wanted their own onstar. It made it easier to sell the cars/trucks into fleets such as rental companies. If I put anything on the CAN bus that device can see it all. Decode what this spids mean is a diff story, but it is pretty raw and unencrypted.

What is the lean method in this case?
