TPMS will not reset

[hwalker911]

I had all four tires replaced a few weeks ago, while there the manager advised me that they broke one of the TPMS when mounting the new tire. It was replaced with a new one from the local Toyota dealership, but now the monitor button under the dash will not reset the warning light on the dashboard. I have tried several time to reset it, but still no luck... Can anyone help me out on what i need to do. Thanks in advance.

Did the tire dealer then have the Toyota dealer synchronize the replacement TPMS unit to the computer?

Didn't think so.

Take it back to the tire dealer, and have him contact the Toyota dealer about what needs to be done next. I think that the Toyota dealer needs a serial number off of the replacement TPMS to configure the computer for the new one. It might need all four.

I suspect the computer is noticing that there are only 3 TPMS units checking in (it doesn't know about the 4th one yet) and complaining about that.

Good luck with the tire shop (who will lose all their profit and then some by paying the Toyota dealer to fix your car).

kohnen is probably correct. This same nonsense happend to me with all 4 tires. Les Schwab Tires had to remove all four wheels and tires, record the TPMS electronic serial numbers, reinstall them all. Then the Toyota dealer had to enter them in the ECM. Now it all works fine.

Thankfully in my case, both the Toyota dealership and Les Schwab felt they should have been more diligent in the first place and went easy on my wallet.

I won't even get into the angst load I had to bear and the wasted time.

IMO, Toyota could solve this be affixing a bright red tag to new TPMS's with the TPMS ESN on it or, if that's too much trouble, a warning urging the owner to record the number BEFORE installing the unit.

i wonder if you really need the toyota dealer to enter tpms serial numbes into the ECM (toyota scantool or toyota toughbook required)??

tpms is not like car keys i think they have to actually share information with third party manufacturers. i bet
in the future more and more tire stores will be able to program the car with the serial numbers of the tire sensors

for example, bartec a manufacturer of tpms equipment sells a box that can program the entire range of toyota vehicles and not just the prius.

i do not think a tire shop even needs to dismount the tire to get the serial number either. you just walk up to the
tire with a handheld device, put the antenna on the tire next to the valve stem (as the wireless signal will not penetrate the rims)
and it just gives you the serial number

sounds to me like tire shops are still paying catch up to the 2007 ntsha ruling

various manufacturers of third party tpms tools even reccomend that the tire store is supposed to walk you around your car
and to verify that all the sensors are working, so they are not made responsible by bogus claims of sensor damages.

curiously 10 % of cars on the road require the use of a OEM scantool or equivelent scan tool to register the tpms serial numbers,
and that 10 % seems to be all toyotas !

Follow up.... First, thanks for all the help. As I found out more, it seems that the Goodyear Tire Shop had broken 2 of the TPMS, so they had to replace both of them. I advised the store manager of what I found out here on PC, and he said he never heard of any such thing. Well, after 2 hours of trying to re-set the tires, he gave in, and I took the vehicle to the local dealership. The dealer explaned that before they could re-set the ECU, the TPMS codes had to be found, old codes cleared from the computer, and new codes re-entered, which they did and all is working fine now.

Goodyear paid for everything, they lost money on my sale for sure...2 TPMS where about $125-$150 dollars each, plus an hour labor charge. If Goodyear had the proper equipment, they could have fixed it right there. Toyota and a few other imports are the only vehicles that do not auto reset. Thanks again...

well lets say they all don't automatically reset, i do not think auto reset is a good term. a better way to explain it is most cars self reset. they will reset the tpms by themselves, but you have to do a specific sequence, similar to turning off the prius back up sensor if you know what i mean

the other auto setting / self setting cars require the use of a magnet that you put around the valve stem to get the sensors to go

and finally theirs Toyota's required use of thier oem scantool (or equivalent third party device)

although i don't have the specific references, i think i heard the federal goverment gave toyota a slap on the wrist for making dealerships use thier scantool, and why their is now third party manufacturers of scantools for setting tpms stems on toyota vehicles.

now if a third party manufacturer can do the rest of the dealer scan tools, that be cool

Clarification please. Can you get a psi reading on MFD or SGII, or do you just get a warning from the ECU if the psi in a tire changes within a predetermined range?

[rigormortis]

psi reading on mfd NO
psi reading on SGII unknown

you get a warning light when the psi has dropped 25% (i think)
