Thanks for confirming AHC functionality! I'm going to buy this and maybe make my wife and daughter split it 3-ways... they're always bugging me about maintenance issues on their RX's.

This thing is legit. Thanks to @Boston Mangler for creating the thread. I was able to easily customize settings as well as make AHC offset adjustments.
The one thing I didn't find was AHC pressures. Perhaps I just need to play around with it more. Did I just miss the parameter?

Mine arrived on Friday. Programmed seat belt chimes off and windows down from fob. Brake bleed procedure will be useful too. Thanks for the info!

Glad ya like it!
Real credit goes to @misteracng that mentioned it. I had never heard of it and was in process of acquiring bits for techstream and already irritated how much of an ordeal it is. This is MICH easier
anyone can create a thread. My plan is to keep posting here if I have anymore time to play with it. Life is kicking my butt right now, but my 200 is completely fixed from mu=y evap issue

The AHC ECU only has one pressure sensor and doesn’t try to help you with front/rear pressures like the 100 series did. It’s not a super useful metric on the 200 series, as far as the data Retrieved from the ECU is concerned.
Definitely a good idea to find something to check ECUs if you own a 200, so not saying you shouldn't go down that road and I don't know if this tool can see the seat ECU, but I suspect it does.
Saying all that, see below for most likely problem. It is possible that something in the seat has become disconnected or failed, which you would need the code reader to verify, and replacing the ECU won't fix.
See this thread, for some reason the passenger ECU fails regularly. I bought a spare LS ECU while they were super cheap (<$20) last year. This summer my ECU died. Was a sub 30 minute repair since i already had the ECU on the shelf.
LX570 Passenger Seat Heater ECU - Possible Solution
I purchased a 2010 LX earlier this year, and noticed fairly quickly the passenger side seat heater didn't work. My first assumption was that it would either be a fuse or a switch, but after finding a handful of threads I learned, that the most likely culprit was the seat heater ECU, which is...

Thanks for the thread. I had been reading up on the heater computer but somehow missed this. Just ordered an ebay 85861-50052 as it was like $55. I love seeing hacks like this, especially ones that save you $900.Definitely a good idea to find something to check ECUs if you own a 200, so not saying you shouldn't go down that road and I don't know if this tool can see the seat ECU, but I suspect it does.

My symptoms are different than mzhu, my switch doesn't light up at all. I'll still be checking connectors and wiring though.
My switch didn’t light up either. In my case, Techstream said it couldn’t talk to the Seat climate ECU at all.
I just got mine yesterday also. will be playing with it this weekend. Interested in how you did the windows down using Fob. Is this doable in for model year 2016? thanks in Advance.
Special Thanks to @Boston Mangler for the information about this unit.

If someone gets a chance, can they see if they can find headlight adjustments. Other posts say it can be done through techstream, just want to confirm before I buy.
Tried to program a key fob in my 13 LX and my wife’s 17 GX. No luck on either. I could see that the LX had 1 spot available and the GX had 2. It would start the process and recognize the original key, but would not find the new one. Also, I couldn’t find a place to manually input the PIN on the new key.

I have this unit and Techstream. Have not tried this test or done any type of comparison but my bet is no. I doubt it's going to run anything above and beyond Toyota's Techstream diagnostics. However, it's small, light, easy to store in the truck when needed.
BTW - spent a few years living in Melbourne back in the day. Awesome place!
@prharper what machine / processor architecture are you running the techstream VM on? Or are you running it on bare metal? I'd love to install it on bare metal but I can't find an installer and crack for a recent version anywhere. The VM posted here on ih8mud is not a solution for me unfortunately, wont even start on my AMD laptop.
I actually moved to near Brisbane now, its got a few interesting spots, but they are all more spread out. I miss the mountains near melbourne!
