How to disable tire-pressure monitoring (TPM) system?
#166
I just ordered Blizak’s and rims from tire rack. I did not order the tire sensors so I will be disabling my system for the winter.
Does anyone know if a 2007 SC430 TPMS is located in the same area and if the procedure to disable it is the same?
Isn't there a fuse yoou could just pull to disable the system?
UPDATE: I got mine disconnected. I had a extra wire harness attched to the middle of the wood piece...not sure what that was for. I disconnected both wire harnesses and put things back together. All went really quick. However, I do have a blinking yellow light....I'll have to tape it tonight.
Thanks

Just disable it.

Ok I forgot. I did the tape behind the IC on this bulb so I do not see it. Suggest you do the same.

I have a 2008 SC430 on which the run flats are to be replaced with standard tires as soon as the tires come in. I have decided to remove the TPMS sensors. I followed the excellent instructions and pictures here to disconnect the TPMS. Everything was as shown until I got to the dual plugs. The large (white) and small (dark) plugs are as shown but are reversed (small on left and large on right). I disconnected both plugs and reassembled the console. When I turn the engine on, the warning light flashes continuously. I note another reference in thread to difficulty with 07 & 08. Does this procedure not work with an 08 or is there an additional step required?
Message #170 makes reference to taping something behind the IC (instrument cluster?) but not clear what needs to be done.
Thanks for any help!

I've just followed the instructions in this thread (esp. the pictures)... many thanks!
My car is getting on a bit now (Oct 2001) and the 10 year lithium batteries have clearly had enough, not a bad run tbh.
Given the battery isn't user replaceable, and new Lexus TPM sensors are £145 each here in the UK (although if I order from Sewells I can save circa 40% on that) I think I'll wait till I have a bit of spare cash and put fresh ones back in on the next tyre replacement... or perhaps fit one of the aftermarket TPM kits that live on the outside (IE on the valve stems).
One of the valve stems is badly damaged... so I might experiment on trying to replace the battery on that one but I'm not optimistic as the batteries seem to be sealed in a sold wax/gel sort of arrangement :-(

Oct. 25 If anyone is interested, there is an SC430 Donut Spare currently on Ebay. See: http://www.ebay.com/itm/LEXUS-SC430-...ca8ed2&vxp=mtr
Good Luck.
Update: I purchased a 2012 Hyundai Genesis donut spare and it fits perfectly. There's plenty of extra room around the brake calipers. I was concerned that I would have to get a special hub centric ring to fit the spare wheel to the axle hub, but the wheel comes with tapered seats for the lug nuts and the stock lug nuts have a tapered section. Put the two together and the wheel is lug nut centered, not needing a hub centric centering ring shim. Anyone trying to put the spare tire on will have to remove the hub centering ring shim required by most new aftermarket wheels to get the spare to mount properly.

I have an 06 and did the mod but the light is still there. I have seen that 06 and newer cars don't respond to this mod... Anyone know how to get that light to go away? Also how do you get to the back of the cluster to disable or cover that light? I did the tape cover up over the plastic, but that is kinda tacky.... Any suggestions appreciated!
