An error in the manual, when changing wheels??

This message may create confusion but I wanted to share my latest learnings:
When shifting from winter to summer tyres I followed the manual for resetting the TPMS. All went well but the error indication started flashing after an hour of driving. Several attempts but all ended with a flashing light, turning to fixed "low pressure warning light".
I called a salesman who informed me that the reset-instruction (in the manual) is meant to be used when you are to change the pressure for the tyres on the car. In my case (changing the tyres and re-learning the system) I should have pressed the TPMS-button 3 times, instead of holding it for 3 seconds. In addition I was instructed to drive the car (after the 3 button presses) around the block - for the system to relearn and turn off the warning light.
This "press the button 3 times" technique is not to be found in the manual, as Toyota did not consider us living in colder countries - where tyre shifting is done twice per year.
 
If you need to rescan the sensors try this:
Set the ignition on but do not start the car.
Push the TPMS switch fast 5 times after another, but the 5th time hold the switch in until the TPMS light starts blinking and then quickly release the switch.
Wait a few minutes, and the light will disappair and the sensors are registered.
 
I've hade the same issue after switching to winter wheels.



They're aftermarket wheels from the local tireshop. I've got the blinking alert after about an hour or two of driving, and the "hold-three-second"-reset didnt solve the problem för more than an hour or two.



I'll try the "push-five-times"-reset later tonight to see if that solves my problem.



Thank you guys!

Did you get it to work? I can't remember how it's done, Toyota wanted 150 SEK ($20) to fix it.
 
Quick and maybe a bit dumb question. But, to turn the car "on" as refered to in the manual.

Is it one push on the button without the foot on the brake? Or does toyota want us to push the button once more so that the instrumentation lights up?

(I'm on my way out to try both three,ferenc method and five presses jolo-method)

Also, my tireshop put in abut 2.6 BAR in each tire, a bit high compared to what the sticker on the door post says, could that be a problem tpms-wise? It's 225/60 17 tires.
 
Might have done the trick.

1. the car is in the desired "on-mode" after two presses of the power button without the foot on the brake pedal.
2. First reset the blinking tpms-alert (3 sec press of set button)
3. Now it's possible to do the 5-press "calibration". (turn the car off, and then press the power button twice to get the car in the desired state for the procedure, at least that's what I did)
4. drive "around the block".

I wasn't able to get a confirmation blink sequence (three slow blinks) from the 5-press calibration until after I did reset the TPMS alert.

Now it's going to be very interesting to see if the error is coming back tomorrow on my drive to work, or if this procedure has solved the problem.

Wouldn't it have been supernice if this had been possible to do on the "settings page" between the two meters in the instrumentation group instead.

I'll report back tomorrow when I know if it helped for real or just for the moment.
 
Hi again.

The procedure last night didn't resolve the issue. After about 20 minutes of driving today, the lamp started blinking, and after a minute or so it stayed lit.



I've been to the local tire shop this morning and they're going to try to copy the ID:s of the sensors from my summerwheels, to the winter wheels. "some Toyota models needs this to be done".

I'll be back when I have something new to report.
 
Well... today on my trip to work, the car all of a sudden seems to have "accepted" the new wheels.

I haven't touched anything related to the TPMS since Wednesday night, over 24 hours ago. Last night on my trip home from work, the TPMS was signalling.

I'm going to the "clone-shop" today, to see if they are able to make any sense out of this.

I've also written about all this on toyotaswedens facebookwall, let's see how attentive they are in that channel.
 
Do you guys think the TMPS sensor is too sensitive in 4.4? I first put more air and it turned off. When weather dropped few degree it came on again and stayed on everyday. It's becoming useless if I don't know if it's really running low air!

My 4.2 did do a correct job and let me manually reset on front dash if I was sure it wasn't an air issue. For 4.4, I don't want to mess with the under dash reset button. Can dealership re-adjust the sensor so it won't be too sensitive?
 
Hi!

Now I've been driving since Friday with my newly cloned TPMS-sensors. The false alarm problem is gone.

The reason I didn't get the alert on my way to work was pointed out to me at the "clone-shop", the summer wheels was in the car. :)

It seems to be one trick that solves the problem, but still, I think that this is a design flaw that Toyota should do something about. Clearly a bit to inconvenient.

Best regards!

Thanks a lot, this was valuable, I will try. Have asked for a quotation to disable the TPMS (which would be the best thing). The TPMS adds negative value to the car, it is only annoying and probable makes the car a bit more expensive.
 
Most Asian-based vehicles sold in the USA do NOT have any provision for auto-learning a new set of TPMS sensors, such as another set of 4 that you might have installed in a winter wheel/tire package. So if you swap 4 tires seasonally in the USA, you might need a 'tool' that interfaces with the OBD-II port to upload a new set of 4 hex ID codes for the second set of tires. I did it for years with an ATEQ Quickset, and for the past two with an Autel TS508.

Many European-based mfgrs have added an auto-learn feature, as have some USA car companies.

Toyota uses multiple sourced TPMS system depending on where it is built, and what engineering team was responsible for design and procurement. Our Sienna van has a TRW system, the oldest and crudest system going. It can only hold 4 hex codes, and only has a simple dash light. Some vehicles with the Pacific system have a full dash display and can hold 5 codes (spare tire). I have heard it said that the 4th Gen RAV4 can actually hold 8 codes, and that it might be possible to toggle between sets of 4 (3 season vs winter wheels). But I have yet to verify this, or the procedure of how to toggle.

When I built my kid's winter set last year (wheels, center caps, tires, TPMS sensors), I bought 4 Autel MX-1 sensors and cloned them to her stock OEM set using my Autel TS508. When I swapped winter wheels on and off, the RAV4 never missed a beat, as it had no idea I'd exchanged wheels. All the transmissions were identical. Problem solved!
