i am trying to find a wiring diagram for that purpose.. haven't located one yet. i also managed to 'cut off the a/c in my messing and trying. i've checked the fuses and they seem ok, but i'm going to check them again. also there is a (can't remember the name of those boxes with the 5 prongs in them that are located in the engine fuse boxes) i have to check and see if i blew that out! ugh.

This is the wiring diagram for the TPMS module from the ES350.

The Blue wire (L) is for the IND (Indicator), the orange wire (O) is for the TPMS reset.

i found a diagram like this for the 06 GS300, but i still can't find the location of the ECU. And, as i said, i tried this with and 'orange box' that i thought might be the ECU (it was located under the glove box as igzy described. but it did not work, and now i've blown out my A/C. i've yet to check the relay (#64) in the engine compartment, but i have checked all the fuses. they seem ok, but maybe i have to look at them closer today. i appreciate any help.

Hi Igzy and everyone,
Who had done this modification to disable the TPMS light and did it work without causing other issues to our cars? I am ready to perform this modification to my 2007 ES350, just want to hear from you all before starting the task.
Thanks,

The mod does exactly what you want - disable the TPMS dash light. There are no side effects.

The mod is also easy to reverse if desired. As stated, I added a switch to allow me to turn the disable feature on or off, depending on whether or not my tires have the sensors installed or not.

The hardest part is soldering the leads while upside down. But it's doable. Just be careful not to accidently scorch something.

Thank you GLC. That is exactly what I need to know, the confirmation of the modification which has no other side effects. I have the toggle switch ready and I will do the modification tomorrow. Thank you!!!


An update: Had the modification done with the toggle switch. It works as design. With the switch the TPMS light can be disable and re-enable when needed. Thank you folks.

Although I do a monthly check I still like the ability to be warned if I have a tire problem on the road. We have 4 vehicles of which 3 have TPMS . The tire dealer I work with has a TPMS meter to check sensors and antenna's . My normal maintenance is to have sensors check yearly and replace as needed. Knowing the batteries usually last around 5 years as soon as one shows sign of a problem I'll replace all of them on that car. It works for us and so far I had never had a false trigger from any of the cars.

Thanks, I just completed the mod on my 2008 Es350 and it works, no more TPMS warning light!

by doing this hack then when you have a flat you wouldn't know, right? why not just fix the issue?

dta20502

You're right, but I do not have money to fix it right now! I installed a 3 way switch so I can toggle it back to original path when I buy another sensor...

You don't have to buy the sensor. You need to change the battery of the sensor.
