Missing TPMS reset switch
Missing TPMS reset switch
Hmmm. 
This is weird. Manual shows TPMS reset switch is next to trunk release button but its not there in my car. Does anyone know where this button is? I have Fsport model with Nav.

You're right I really had to look hard and touch every where under kneeair bag area. Found it next to odb port. Why did Lexus made this so hard to reach.

Q: On a related note, can the 3IS recognize two TPMS sets like in the 2IS and do we have to get this programmed by Lexus or it's a DIY task this time around?
Seasoned Lexus owners are probably chuckling here since this has been the location of the TPMS for most of the last 2 gens of several models and it's always been a pain to find! I'll have to get on my hands and knees again, twist my back to find this darn button

If we can disable the warning on the 3IS, I'm good with that, but if it's like the 2IS, if you don't have TPMS on your second set or if it's not registered, the warning is on all the time
There must be a way to register a second set but haven't read thru the book yet.

I was told by a tire shop previously that with two set of TPMS on the system, Toyota has some problems occasionally which busted the system somehow, So Lexus/ Toyota has changed the design by using a reset button.

I won't be surprised there is only a reset button as Lexus has changed the way the TPMS is registered in the system. On my RX, I can only see the reset button as well. So every time you swap a set of tires and rims, you follow the procedure in the manual to register your other set of TPMS..

For the RX, I believe I had the tire shop putting everything together (TPMS, tires and wheels)

I got myself a second set of wheels for winter. I also bought the TPMS transmiter for them and they are installed right now. Unfortunately the TPMS on my 3IS only has 1 memory slot and I haven't find a way or the tool to flush that memory and be able to do the switch myself. Since the dealership charges me $75 to do it, I rather research and buy the goddamn tool so I can do it myself. So for now, on my winter tire set, I have a permanent warning light on in the dash...
Anybody know what is needed to do this at home?

ATEQ QuickSet Tool
I purchased one of these and have successfully retrieved the current TPMS sensor codes from the ECU. I'm not anticipating any issues with uploading new TPMS sensor codes to the ECU (overwriting current set). Still waiting for winter tires to arrive so it will be a few days before I can confirm. Purchased tool from www.racing king.ca

An alternative to reprogramming your TPMS is to get clone type sensors. I did it and had them cloned to my OEM sensors. They work perfectly on my winter tires and I never have to get the ECU reprogrammed. The only disadvantage is that they were about $20 more each compared to the regular TPMS. It's worth it though because Lexus quoted me $65 for each time they have to reprogram it.

FYI - mine are EZsensors which have not been easy for me. My tire shop claims the problem lies with the programming and it is on the Toyota/Lexus side that Bartec USA couldn't resolve yet.

Can your clone type sensors display pressures per location on the dash? Mine didn't and I waited for 2 years (Sep 2013) before I gave up having my IS as a testbed for Bartec and demanded the tire shop to replace them with OEM sensors recently. Problem solves. Pressure comes up on the dash and I find it very crucial to see what is happening in winter driving.
