DIY - Bypassing Tire Pressure Warning System (TPWS / TPMS) - Toyota Yaris Forums

Tiddlygoose · 01-20-2009, 11:49 PM

OK, so I followed the first mod as CTScott knows... Then I followed the corrected 2nd version of the mod. I Left the first switch in the on position, Added a second push button switch with the 3 150 ohm resistors and it worked right up until the time I got up to highways speed. Then the darned light came back on. No amount of changing either switch changes anything at all.

Question. Can the dealer disable the entire TPMS system, even if it costs me? Has anyone had that done or know anything? I always check my own damed tires. I've never had anything like this to fall back on before and with my tire switching situation I'd just as soon loose TPMS all together at this point.

The dealer can't disable it.

Can you take some pictures of your wiring, so I can help you troubleshoot it?

Mine has been running fine disabled (no light) since I posted the updated version on 11/30/08.

I haven't even ef'd with the fix yet. I got just about every damn warning light on cause I switched steering wheel , rims, seats, seatbelts. At this point its probaly just easier for me to pull out the gauge cluster and pull the light bulbs out , Lol.

Cool, I appreciate it. I think at this point I shall wait until it warms up above freezing. I nearly got frostbite on my fingers when I did this a few weeks ago... I will live with the light for now.

I am still happily driving around TPWS light FREE!! I followed the 150 ohm procedure without a switch.
