I think it has to do with a switch in the passenger footwell. You can have two set of TPMS', one for Winter Tires and one for Summer tires. You use the switch to go from season to season.
I have never used it, so you probably want to do a search for" winter tires tpms" or something like that.

this applies to a first or second set.
Just saw this post after making a comment in the other thread. Still hope you would be willing to detail how to add a second set of TPMS sensors in the other thread for the sake of completion. Hopefully. Thanks!

I bought one....was told it would work on my windows seven machine. Sent with specific instructions on how to load software....how to bypass key. A lot of computer mumbo jumbo. I couldn't get it to work ......contacted seller in china...he was very helpful...he spent a couple of hours trying to get everything working...never did...he sent me another cable...I tried to load it...didn't work.I looked at buying a laptop at local comp store for $85....but decided to cut my losses and said F-it. I am retiring soon...so some day when I am bored I will try it again.
Hope your experience is better.

again, the steps are exactly the same except you select 2nd set.
BTW, did you see the link I left you in the other thread I started?

i don't have a second set of sensors, I actually showed you the steps in a different thread a couple of years ago, I saw it last night when I did an advanced search, keyword tpms, user bgw70
again, the steps are exactly the same except you select 2nd set.

I am new and looking to change some LPS on my 2007 rx400h. Which cable and software version works with them ?? I tried a couple of cables one from ebay and one from amazon and neither gave me the utility choice to change anything nor any way to install a different remote. The old way of opening the door and closing etc did not work for me either. I wasn't educated enough at the time to check for version and just sent them back. Now as I read more maybe I can do more. If you have any insight as to what will let me into my 07 400h please let me know and thanks for all of you that have posted for the rest of us. Carl ps I had no problem installing the drivers nor connecting to my car with either cable. Running win7 32bit recognized instantly and would open techstream just no utility choice to change things. I did read that there was a change to the Toyota mastertech around 06 but it looks like the techstream takeover was supposed to be backwards compatible ??? Thanks for looking.

Thanks Bgw70 for your reply. I had done a search for the title of this discussion "Techstream Cable Firmware Software Version Help" and did not specifically search for RX's or Sc's. I was not trying to hijack this thread so sorry if I stepped on any toes. Just trying to see what version of software and firmware will help me to learn how to make the changes that I would like to do. Thanks , Carl

like I said, if the 2010 Camry and your car run the same bus type, the 2.0.4 cable firmware chip worked for me. Cable Firmware is they key.
dont worry about the software version as much.

I don't know if this will help you but i bought my cable and software off amazon and the techstream software was 12.00.127 and i had the same problem. I did not have a customize or utility button to make changes. i downloaded firmware version 12.10.019 and installed it and that fixed my problem. I am not able to connect to my 08 lexus sc430 and 16 rx350 and have the customize and utility plus a couple of other buttons. Like I said not sure if this will help you with your 07 rx400h.
and I think you meant the software download now allows the cable to connect to your SC and RX, is that true?
do you know if you cable has firmware v1.4.1 or v2.0.4?

Thanks Tom and Bgw70 for your replies. Tom if and when you have time let Bgw and me know which cable version and the confirmation that you COULD get into your SC and RX. I know mine is older so there might be aproblem for me but this is a good start. Thanks to you both. Carl
