Just wanted to clarify the description:
0. Disconnect the battery
1. Unplug the wiring harness
2. Locate pins 5&6, dark green and light green next to each other. The dark green is the light output, and the light green is 5vdc supply to the antenna module.
3. Just add a jumper between the two wires
4. Plug the harness back into the module.
5. Reconnect the battery
6. When you turn your ignition on you should no longer see the tpms light.

That would be correct, except disconnecting the battery is personal preference and not necessary.

Just curious if anyone has explored this as this could present problems for those of us who have to get annual inspections on our vehicles.

The tpms module is pretty much a stand alone unit and it does not tie into the main computer that triggers a check engine light or can be picked up on a obd reader. Sure the module will realize there are no tpms sensors present but because the dash light circuit is being supplied by 5vdc it will never drop out to ground and turn the light on.

Btw the tpms modual in my 2018 limited it grey in color. But the wiring pinout appears the same. I’ve done the mod. Seems to work after 2 weeks. So still good here. One note don’t pull your plastic off in the cold!

Where are you that they check tpms on mvi? Just curious?
Anyway maybe a safe mod would be. Have 4 extra sensors, have them programmed like I did for the tundra. Then I installed them in a 4”PVC tube with a valve installed in one of the end caps. I’ve used it for 7 years in 2 tundras.
I was lazy, is why I did this join the wires together in my 2018 4Runner and lack of storage in the 7 seat version!

I am not speaking from experience but in general. In PA, this is not a requirement but I am not familiar with inspection requirements throughout.
I will admit I personally was not aware that the TPMS system was basically a stand alone system. I originally thought that maybe a TPMS warning light would affect traction control or some other safety system when a low pressure is detected. Which in turn might result in trouble with an inspection.

My 4Runner passed inspection with the TPMS light on, my Acura has passed with an ABS light on, it's all subjective in PA

It is good to know that it can pass with the multitude of lights. Hopefully not an issue that anyone has to explore anytime soon though.

If you really do want this mod. Well there’s another option. Instead of just the jumper wire, a single pole toggle switch could be installed and used to turn tpms on and off.

I actually joined this forum for this specific post. Has anyone else done this? What has been your results? I've got an '11 SR5 and I am planning on doing this today.

Let us know how it goes. I haven’t done it yet, but know I will need to someday on my 2012. I’ve done both of my 2006’s successfully, although a different method.

As to not make a new post for this, is there any way to actually see the tire's PSI readings?

Well, my attempt did not go well. The wires are much smaller than they appear in the picture. The insulation measures right at 1mm. I'm guessing it's either 28 or 32 gauge wire. I didn't have access to a connection capable of such a fine wire. I'm going to revisit it when I get some micro connectors and I'll keep everyone notified.

Great info! I want to switch to rubber valve stems instead of the metal ones. Broke one on a rock. I’ll be doing this tomorrow.

This is exactly why I want to do this mod. I have Colby valve stems for emergency (they insert from the outside) but would feel better to have rubber valve stems so they have some chance to survive a rock rub.
