I dont know if this makes a difference but i Dont have a brown cable on mine I have a white with a black stripe were that brown one is on your write up. Any suggetions. thanks for all your help.
Can you take a picture of your connector? The part number is the same for 08 and 09 sedans and LBs, so even though the wire colors are different, their functions are identical.

If your connections are in the correct place, try measuring the voltage on the "brown" wire with the switch in both modes. With the TPWS connected (and the sensors not present) you will read ~1 VDC. Withe the TPWS bypassed you should read ~4 VDC. If the voltage is less than 3 VDC, the light will remain on.

If you do measure less than 3 VDC, you will need to change the resistiors to 150 ohm, 1/2 watt ones.

Hey CTScott thank to you the light is gone. The first time the light came on again but when I got home I change the blue and the yellow cable around and the light was on I click the switch and the light is gone. Thanks for all your hard work.

I can let you know tomorrow I just got done changing the resistior to the 150 omh 1/2 watt. I had the 10 ohm that i install the first time and the light would stay off the first day and it would come back on the next day after the first 15 min ride.

Thumbs up

I put in the 150 Ohm resistor mod on Dec 2 and have had no problems in the ~150 miles I have driven since. I did not do the switch procedure as I do not intend to EVER go back to a TPMS. I personally see absolutely no value in TPMS whatsoever for me.
SO, if I ever buy another new car I will do this all over again!

Yes it does work the 2nd day in the road no light. With no switch.

Just to verify:

If one chooses to do this mod without the switch, the connector remains UNPLUGGED from the TPWS module?

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.
