Tire Rotation - TPMS Recalibration needed or not

[brumey]

I am at the Toyota dealer right now and having oil, filter and rotation done. I read somewhere online that after the totation, they have to recalibrate the TPMS system so the tire pressure display is accurate and knows which position each tire is in (front, left, rear right, ect.)

I ask the service advisor if they do the recalibration and he said no. He then asked one of the senior techs and he said it’s automatic. He said they adjust to the new on the vehicle.

I need to know if they are correct? When I get home, I will deflate a tire and make sure it shows correctly.

In my little mind, it seems that you would need to associate a location on the vehicle to display it correctly. If not, it could show the front left low yet it could be any other location.

thanks

TPWS is what toyota uses not TPMS

PAGE 545 of manual

the radio learns position automatically because it knows the round trip time
of a signal to any corner of vehicle and the spare

Registration of the tire position
1 Park the vehicle in a safe place and stop the engine for 15 minutes or more.
2 Turn the engine switch to ON. Registration cannot be performed while the vehicle is moving.

Press or of the meter control switches, select “TPWS Setting”, and then press “OK”.

Press or of the meter control switches, select “Tire Rotation”, and then press “OK”

Drive at approximately 25 mph (40 km/h) or more for approximately 10 to 30 minutes. When wheel position registration is complete, the inflation pressure of each tire will be displayed on the multi-information display. Even if the vehicle is not driven at approximately 25 mph (40 km/h) or more, registration can be completed by driving for a long time. However, if initialization does not complete after driving for 1 hour or more, park the vehicle in a safe place for approximately 15 minutes and then drive the vehicle again.

Well, while waiting for oil change and rotation, I downloaded the owners manual. Page 545 clearly states that you have to reset the tpms after a rotation. Its good that the owner can do this themselves.
Its not good that the dealer did not know this and is not doing it. The potential consequence is someone getting a low tire pressure alert could checl the claimed position on the vehicle and find it fine yet another tire could be low. I’d say that is a safety consern.

I said I would do it myself.

I think we are on the same page. I did not see the comment about the radio learning the position but I assume that is not automatically done, it does that during the registration process, right?

If the registration process was not done, it could flag an incorrect wheel warning, right?

shoukd the dealer do this process for the customer if they did the rotation?

Pretty sure they can't know or remember every single thing on every models.

I am pretty sure they should have a checklist to follow that eliminate lack of memory or each task. Unbelievable what we let dealer service departments get away with. In many cases, I go in knowing more than the advisor, not just Toyota.

If it was an independent shop, I get it but, Toyota only, come on!

So, I get the vehicle back from the dealer service dept. I did point out the details in the owners manual but stated I'll just do the reset as it's easy to initiate.

QUESTION - When I started the car, I saw a display stating it was reseting the tire PSI while driving or something like that. So, did the dealer initiate that setting before getting it back to me or is it smart and know when you have rotated the wheels without even driving it?

Another snafu happened as I started to drive out. The car was binding up in the front. WTH.... After checking visually, I checked the 4WD knob and saw it was in 4H. It was not that was when brought in and I only do that every couple of months on loose gravel roads. Was it an accident by whoever operated the vehicle in and out of the shop. As Y'all know, it had a button that has to be pressed in to rotate the control so accidental change is unlikely in my opinion. A tech came out to investigate and states, "it happens all the time", accidental, that is. Well, I have never accidentally done that.

I'll Give the dealer another go. It was a Monday morning so, I guess not the best day to get alert technicians.

the question i have is, when did you put a 5th sensor in the spare tire? i thought only the higher trims came with a 5th sensor?

or did they take the tire sensor from the tire taken out and put into the spare position?

Nodak - Not sure where the 5th sensor came up. I only have the stock OEM spare for the SR5 and ithe display only shows the 4 main wheels. What am I missing

so in other words, they removed 1 sensor from a tire and put it into the spare tire that was rotated in.

on the higher trims of the 4runner all 5 tires have sensors. the lower trims only show 4 sensors

as you can see from the dash on my platinum

Not the case. This was a simple 4 wheel rotation. Nothing touched the spare which I believe is a temp tire anyways. They rotated per the manual, moving front to back, keeping each on the same side.

My spare does not have a sensor and only displays 4 wheels.

Not sure where the comment comes from on the spare, did I misspeak?

ugh my bad, i think i derailed the whole convo. i was thinking you rotated the spare in

 

[brumey]

No worries.
I still would like to know if the system TPWS magically knows there has been a rotation of if the dealer initiated a reset in the console or via a dealer tool.

initially speaking to two tecks and an advisor, they said the do nothing with the TPWS for a rotation. Maybe they looked in the manual after I spoke to them.
Anyone else notice the dash TPWS display reseting on the drive home from a dealer saying its figuring out wheel location?

from what i can tell on a reset, the tpms computer (ecu) will relearn where each sensor is located at and assign the sensor id to that location for future reference for a faster reading. it wont relearn a location once set (ecu)

hence the reset sequence needs to be done per the manual and then the vehicle needs to be driven for a short distance over 25 mph.

it varies on distance and speed, some places say highway speed across 5-10 miles.

This is my experience. I have a second set of winter wheels with new never used Toyota TPMS. I used the settings to indicate that I installed the second wheel set (you can ‘register’ two wheels sets).

After I installed the second set of wheels, I received the same message you did – something like “wheel location setting while driving”. After two 10 mile trips, the truck figured out the location of the individual wheels/TPMS and the light went out and the correct pressures indicated. Magic!

So yes, the TPMS magically knows what is where!
