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One final item, my car shows out-of-date firmware (1.3.83) and the software wants to update to 1.3.101.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.
