If that fails, try removing and reinstalling TS and try again or try installing a different or older version. I'd try to reboot TS with the key on ACC procedure and see what happens. he MongoosePro® Toyota 2 is a compact and rugged, SAE J2534-1 and J2534-2 compliant Pass Thru vehicle communication interface that connects your Windows computer to a Toyota, Lexus, or Scion vehicle, allowing you to perform OE-level diagnostics and ECU reprogramming, using Toyota’s own Techstream software. For sure these systems are sensitive to electrical inputs, especially can bus with ground issues, or say like removing the positive battery terminal first can cause unwanted problems. I haven't heard of the hacked TS versions we're all using causing any ECU related failures- but I suppose anything is possible with a virus laden disc or a poor ground between the computer and the DLC.

Periodic software updates will be available to support new models.
Techstream Scantool Diagnostics: TIS techstream offers full support for 1989 current vehicles marketed in the United States. are you running the mongoose techstream light cable sonk76. TIS techstream is the replacement for the Diagnostic Tester and can be used for all Toyota/Scion/Lexus vehicles marketed in the United States. What machine (32 or 64 bit) and what version of TS software are you using? That might help someone else to offer some suggestion. techstream 12.20.024 is pretty outdated current version is 13.30.018. Its possible the error code you are seeing may be a glitch with the version of the software it self.
If you dont follow the right boot sequence it won't work right. Sorry I am no TS expert, I've used it conservatively on my truck to check things and gather data for about 3 years. So disregard point #5 in your list- I doubt that is the issue. I misunderstood- I thought you couldn't clear the TPMS DTC. I was responding to the earlier post regarding your issue was still related to DTCC2125.
