TPMS and tire rotation on 2017 LE
When rotating the tires on my LE does the ECU have to be updated with tire position or do the four codes loaded in the computer figure out where they are automatically?
The reason I ask is that I am going to mount a set of winter tires on a spare set of rims and the tire shop says they can "clone" my present sensor numbers onto the new programable TPMS sensors. If I ten choose to change the wheels/tires at home, do I need the tool to reset the ECU to where the tires are positioned after the change or is the system smart enough to determine where the TPMS are after the wheel change without reloading the new positions?

You don't need to do anything but there are 5 TPMS sensors...the spare has one also.

ECU does not know or care about tire location, all TPMS is doing is comparing pressures. If there is discrepancy such as one tire is 6 psi less than other ones you will get TPMS light. 4th gen owners would get this all the time in winter because spare has TPMS and they would forget to inflate that fifth tire to match other 4. As for cloning sensors I'm skeptical because your system is only accepts 5 serial code numbers and I'll be impressed to see tire shop flawlessly hack into those codes to make identical twins of 4. GL

ecu knows about the locations and the pressure at the locations, but it doesn't display it. You can get a aftermarket NAV and it'll read the tpms data and properly display it.
it is very easy to clone tpms sensors. Just that the clones won't be oem denso.

FWIW, Techstream on my '15 LE just shows 5 positions labeled 1-5.

Maybe I'm missing something but I don't a location indicator in the screenshot. There are sensors 1-5 and all the info from the sensors. I don't see anything on the screen that locate sensors 1-5 to a location.
When I talked to the dealer about my Toyota Care tire rotations, they said the 4Runner doesn't track the tire location. There is nothing they do in the ECU when they do a tire rotation.
I follow the below rotation and NOT the Toyota suggested method.

Five (5) Tire Rotation
While many vehicles are equipped with temporary spares that cannot be included in a tire rotation program, if the vehicle's four wheels and tires on the ground match the spare wheel and tire (if non-directional and not branded "for temporary use"), they should be included in the tire rotation pattern. Follow the vehicle manufacturer's recommended tire rotation procedures, or if not available, insert the spare in the right rear position at every rotation. Place the tire that would have gone to the right rear in the trunk as the spare until the next tire rotation.
On front-wheel drive cars with full-size matching spare, rotate the tires in a forward cross pattern (Figure F)
On rear-wheel or four-wheel drive cars with full-size matching spare, rotate the tires in a rearward cross pattern (Figure G)

so you just drive around with one steel wheel? how do you do a 5 wheel rotation?

Unless you tell ECU where each TPMS is located and then somehow update it every time you rotate tires - there is no location priority.

The Limited has a matching alloy rim. Hence the 5 wheel rotation done on the Limited.
This is the Toyota suggested 5 wheel rotation. Note that in this method not all tires wear equally.

It is right to buy four-piece aftermarket sensors.
To clone with the original numbers.
So changing tires from summer to winter will not require training with other numbers.
Or to put original or other sensors with other numbers, but when changing tires, you will need training with diagnostic equipment.
His ecu needs to know the numbers of the screws he does not care otherwise.

And now I'm getting ready for a winter set
But my diagnosis techstream does not open the controller and I use texa axone s tps and launch for that.

2014 updated to a regular alloy spare instead of the yellow.

Mine is Yellow, but the truck is a 2012. Apparently the new ones are not yellow.

My 2014 has a yellow spare with no TPMS.
