    Review (feedback)

    dfergendon from California write

    “… I want to express my appreciation for Alflash whose remote diagnostics and guidance saved me at least days and perhaps a week in making this repair. I’ll describe my interactions with him later but for now it’s enough to say that he’s an honest Ukrainian mechanic, not a malicious cyber criminal preying upon the RAV4 EV community.”

    “…A huge thank you to a few members that helped me diagnose my Rav4 EV, but also helped me through the repair process. Volodimir Leshchenko helped diagnose the vehicle from Ukraine amidst a war with Russia. He also provided very valuable info on diagnosing contactors and how to test them. He has a plethora of videos he has made to help with this vehicle. Thank you Sir. Your knowledge is appreciated.”

    “… Enthusiastic DIY owners contributing on forums like this, and experienced Rav4 EV professionals like Vladimir are the only resource to keeping these cars on the road.
    Vladimir was patient and persistent, and a total pleasure to collaborate with. I couldn’t recommend him more highly. It would be something special if we could teleport him around the world to work his magic.”

    Description (ONE out of three possible) of the method for implementing remote diagnostics

    To diagnose and collect data from Tesla electronic systems of Toyota RAV4EV aka Tesla Electric Propulsion Control System a standard network cable with LAN (RJ45) is used; one end of the cable is plugged in the connector on Mikrotik router, the other end should be connected to the blue diagnostic connector DLC3 No. 2 as Toyota calls it.

    1. We can’t repair your Vehicle.

    2. We can only do remote diagnostics of the RAV4EV using the Tesla program and let you know its results (fault Codes, Data Stream of Tesla System, Active Tests, Clone of Gateway, etc.).
    Based on the results of the diagnostics, we will also provide you with results of diagnostic, recommendations and give you technical support that is relevant to the Vehicle problem found. And we can do reset the codes when the problem is fixed.

    3. How is the diagnosis shown in this picture.

    Cable and router MikroTik with Wi-Fi are required (any of these ).

    For the manufacture of cable connections to Tesla need to buy
    – connector (for example)
    – patch cable (for example)

    For the manufacture of the cable, it is sufficient to correctly unsolder only 4 wires (a link to the diagram will be shown to you). (Illustration)

    An example of making cable

    Before diagnostics, we need to configure your Mikrotik.
    1. Mikrotik must be connected to a laptop.
    2. Run the Teameviwer program and tell the Network name and password where the diagnostics will be done. My tech support will be able to configure yours router.
    Then you connect the cable to the blue tesla diagnostic connector , and the other side to the router, turn on the ignition and we can make a diagnosis via the Internet.
