If you do this, don't forget to check your tires regularly.

Thought this would be a good place to post this as it's relevant info for the TPMS valve stem hardware. Found out that the units use a lithium ion watch battery. The battery is soldered into place and should be replaceable once the valve stem unit is "forced open." Something to consider if someone (like myself), wants to keep the TPMS active. Panasonic BR2777A 3Volt. Just searched and didn't find any for purchase but here are Tech Specs. Maybe someone can find a suitable replacement?

Technical Specifications:
Nominal Voltage (V): 3
Nominal Capacity (mAh): 1000
Diameter (mm): 27.5
Height (mm):7.7
Approx. Weight (g): 8

The 2777 in the part number refers to the thickness and the diameter of the battery cell. If you can't find the BR2777A specifically, then find one that will fit in the space allowed. Is there room for a larger battery? If not, then there is a CR2477 that is available that would fit, it is just that the diameter would be a bit smaller and will likely have a bit lower capacity. However you will likely not even notice that little difference in capacity. It would last plenty long, if you are able to replace the battery.

However, having said that, be sure to check the temperature ratings on the batteries. The BR may have a broader temperature rating than the CR. If that is the case, search for a BR2477 or something similar.

My 2004 LS430 has the low tire message and warning triangle on. I was told my car didn't actually have tire pressure monitors in the tires. But that the ABS sensors detect differences in the rotation or some thing like that.
Is this true ? I really hate that red triangle glaring at me. I've already had the pressure checked and their all good. I'd like to just disable the system.
Anyone have any bits of info. for me ?

Default Same Issue With TPMS

and I have had other cars with tpms and they weren't annoying like the lexus! I notice the small stuff is all freakinn annoying, even changing your bulbs, specially the fog lights which is a PAINN.

I actually have a US car so once i got new wheels, the light was solid for few months with no beep or anything.. then randomly one day it started blinking and beeping, the most annoying sound in the world.. I took it to the dealer they said by law they could not remove it. So i disabled it myself and took less then 5 min, no light on dash, no sound. Can drive peacefully now !!!
I am having the exact same issue -- after years of the same rims without sensors and no issues, currently beeping & flashing and dealer claimed could not re-initialize and recommended 4 new sensors. I would like to disable as you did but don't have the confidence. I am in Toronto as well -- downtown. If you are willing please email back and perhaps you can guide me through or suggest someone in our city who knows how to and will perform the disable. Thank You. : )

The instructions are in the early part of this thread. Start at about post 12. In post #3 is a link to a GS process.

Great info. Thanks. I bought a tiny tpms that works very well on the valve stems themselves and shows actual pressure and temps and alarms. Will disconnect the oem tpms versus spend $500 plus fixing the failing oem systems batteries.

fits into the cigarette lighter hole under the cover. Cover closes. Adjustable alarms. Much better very accurate. Inexpensive

Hi there,

Thanks for sharing the link for disabling the TPMS...

I have a 2005 Lexus GS430 and have now started receiving the "Check system" errors on the dashboard (despite the sensors only being 12 months old at a cost of £160, and also
£130 for Lexus dealership to calibrate them for me... I really don;t want to fork out £280 every year to pass my MOT... so could anyone plse confirm that the procedure for
disabling the TPMS on an GS430 will be exactly the same as for an SC430? Cheers. Steve
