5th gen TPMS disable

TPMS disable solution

Since this is my first post here I couldnt start a new thread, however, I do believe I have the bypass solution for 5th gens. I have a 2018, I bought access to toyotas technical information system to download the schematics. It turned out to be the same as my 2014 Tacoma. The tpms light needs to see 3.2v or higher to stay off, unlike a ground on older generations. No big deal heres what I did. Drop the drivers side dash panel below the column. Look to the left of the column and there should be a gray box with one bolt holding it to the subdash. Unplug the wiring and locate pin 5&6, dark green and light green next to each other. The dark greeb is the light output, and the light green is 5vdc supply to the antenna module. Jumper those two wires together and plug it back into the module. The test is when you turn your ignition on you should no longer see the tpms light. I havnt driven yet but so far this looks like the solution many including myself has been after.

Just did the mod today and it seems to work! One key note is not to completely cut the dark green wire, just add a jumper between the two wires as was described. No more annoying indicator!

Nice! I have planned to not install tpms sensors with my new wheels. I wanted to make sure this worked before I went thru with the mounting and balancing, glad to hear it worked.

I can now confirm this bypass works. I installed my new wheels and tires the other day without tpms sensors, and have driven over 100 miles without the light coming on. :banana:

Well done sir. Been waiting for this.....

I’ve got a 2018 limited as well. THe only difference is the control modual is blue, however the wire pin out is the same.

Quick question for anyone who has done this mod.

Aside from turning off the indicator light, does this also prevent any other error codes or warnings in the system?
Maybe I am way off on this one but I would think that even though the warning light is no longer present, somewhere in the system it may still indicate the sensors are not active and the system is not getting a reading.
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.

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.

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.
