I tried the second cable and had the same results. So I had to spend some time wrangling with the PC and got the connection working with both cables. So no issue with either cable. I'm going to gift the second one.
An annoyance I noticed this time that may be what I remember with the VIN from back in November -- when you Start an Alert Log download the connection seems to reset several times and the VIN disappears.
One final item, my car shows out-of-date firmware (1.3.83) and the software wants to update to 1.3.101. It's really annoying during the Alert Log download because it asks every time the connection is reset. Should I attempt this update? The other day I found a doc on here that looked like instructions, but not finding it at the moment.

Someone with better sources can correct me, but .101 or .103 fixed the speed sensor range drift issue, I think? I could be mis-remembering. I'm too drunk and lazy tonight to go dig through the TSBs.
Firmware update instructions mentions connecting the Toyota GR8 (something like that) before starting, and I heartily agree: make damned sure that you have a battery maintainer on the 12v battery before starting the firmware update. It's important. Do not assume "oh, the battery's fresh and charged" will make it through the firmware update. My warning.

It is also important to note from the update instructions:
THE EV POWER MANAGEMENT ECU MUST BE REFLASHED BEFORE THE ELECTRONIC PROPULSION GATEWAY CONTROL MODULE OTHERWISE ECU DAMAGE CAN OCCUR.
Using Techstream (different program, different cable; search the forum for info if you don't already have it), confirm you've got the latest firmware on the EV PM ECU: main version should be 896B34201500, sub should be 896B54201300. This should have already been done at a dealership when they also updated the gateway to 1.3.83 under a prior TSB. Once you've verified this, you can proceed with updating the gateway to 1.3.101

Yes. I just assembled ten more last weekend, and shipped one Monday. Payment instruction is in the first post of this thread.
I have built (38) cables, and shipped (29) to date.

is there a quick guide to using one of these now that i have one? (what software do i need, where do i hook it up, what do i have to do with the vehicle to make it talk to it etc.)?
The software that this Gateway adapter cable enables is Tesla Powertrain Diagnostics (TPD). Info on obtaining and installing TPD is here. It's widely available in the original v1.1.42 as well as the newer and slightly less capable 1.1.46 . The latter is, however, much easier to install and maintain.
Using it is a matter of poking at it and seeing what it does. It's mostly valuable to see Alerts (what Tesla calles DTCs), to see the spot values of various items (eg how the DC-DC Converter is working, what the 12v battery voltage is, is the OBC able to detect CP correctly, what is the state of the HV Contactors), but it does have a few tools available, such as the ability to run the three coolant pumps at 100% for ~33 minutes to purge air from the two cooling systems.
There is no Help manual for using it, so you have to blunder about. There's a Help button, but it shows you how to do things like prepare a log to upload to Corporate for review, not how to use the software as a tech.
The adapter cable connects to the second OBDII-like connector, located at the left rear of the RAV4 EV, behind an access panel. It's referred to as "Diagnostic Link Connector" DLC3 No. 2 in the Toyota docs, to distinguish it from the typical OBDII connector under the steering wheel area.

- To work with the Toyota systems, you use the front connector + Toyota Techstream software and a J2534 dongle cable.
- To work with the Tesla systems, you use the rear connector + TPD and this adapter cable, which enables communication with the Tesla Gateway module.

I need to buy a cable Please. How can I buy a cable?
I can't make this any plainer:

Man Al, you're everywhere! Your forum post is as helpful as ever...have a dead Rav4 EV, need to diag to fix it. PM incoming.
PS. Your pile of goodies for the OM606 you sent me is still helpful. Replaced a lower charge pipe and the turbo to intercooler pipe from your spares when my sister ran over a curb.

Two more cables going out tomorrow.
I had thought that, after the initial that I would only need to assemble a couple a month, but interest in these seems to actually be picking up. I suppose more RAV4 EVs are out of warranty, have hit their 2nd/3rd/4th owners and are all going to DIY-ers now.

One is going to "JB" who sent funds by PayPal, and I didn't get an email address for them, so . . .

Thanks, Al. I would have thought email was included in the PayPal transaction but now I learnt not. I’ve had my car since 2013 and had to replace onboard charger fuses not long ago. Your posts were really helpful!
Incidentally, I was able to change the fuses without having to remove the charger completely - leaving the HVJB intact. This saved a lot of time. See attached photos.
