Found it! Thanks!
With your help, I finally found the switch.
Strange hiw no one else seemed to know where the switch was, or were unable to describe it.
Thanks for your clear instructions!

Mods, I cannot find any information in the LS430 FAQ thread about how to initialize the TPMS system. It might be nice to add this thread, especially Post #11 in there as I usually see someone asking about this topic fairly often...

Everyone needs to have an owners manual and actually read it. You can get a free one from mylexus.com. Just log in with your VIN No. and order it online. It's a long read with a lot of photos and all the info you mostly need to know to operate the car.

In case if your wheel bearings are ok, you may be dealing with tire damage. For example, damage occurred under the threads. This will cause Low Tire warning signal to show even if your tires have even pressure. Remember, the system is not capable of knowing exact pressure due to lack of sensors (which is good), but rather rely on “other” information to determine if you have a problem over there.

Good advice Jay but the percentage of people who actually read the manual, much less the whole thing is depressingly small. The easiest way I've found to find information on almost anything is to simply Google it. It's actually how I first found out about this site while I was evaluating an LS430 for purchase. It's always nice when people do their homework first but for those that don't, the FAQ section is a big start for finding answers to your LS430 problems...

Have you performed a standard Initialization according to the procedure? Do you feel that during driving at speeds above 30 mph you need to constantly adjust steering for straight direction? What brand are your tires and what is the pressure and your style of driving?

yes, twice as I stated in the original post. Th tires are wearing normally and the only pull is when on a crowned road and it pulls slightly to the right side as to be expected. Total mileage is only 63,000 so not likely that the suspension is worn. The tires are Michelin and about 50% wear.
Here are my next thoughts. Your tire verification system is working fine, we are looking here at 63k mileage and very low chance of ECU (ECM) malfunction. The system alert is triggered by differences at how effective your tires rotate. One or several of them may have something on the treads, or in worst case scenario the tire damage already occurred. I suggest to visit local tire shop and have them look at tires, and specifically if your treads are already forced inside or outside of the normal circle structure.
I am not a tire expert, but the case that I am describing happened to me a long time ago. Once the tires were replaced, LowTire warning never came back.
Question. When you drive high speed on the interstate and press the brake hard enough, does your car want to pull to the left or to the right?
