Write-up: How to Disable (Bypass) the TPMS

Tpms

Worked on my 05 4runner. Thanks!

Note: My two pink wires didn't have definitive markings. Had to look a little harder. There's a pink and blue also.

However, was real easy.
 
I did this yesterday on my 2007 too. I decided to take the pins out of the connector and then plugged the pins into a quick disconnect terminal.

Just finished this mod. Works as described. 05 T4R, I will say make sure you have your wires in the correct channels on the connector. I didn't have one (white and black) clear and I cut it in two. I simply spliced extra cable then connected the scotchlock. I am going to solder the original wire back together this weekend for a more solid fix. Just a FYI be careful with these flimsy little wires.

On a side note, does anyone know if the entire plug control anything other than tpms?
 
I am wondering what you folks do when you buy new tires? Most reputable tire shops will not install tires if the TPMS is inoperative.

With this mod, they will never know unless they do lots of extra fiddling related to trying to sell you new sensors...

Right I mean its true. How would they know if there was TPMS on these vehicles? Not every vehicle has this option? Even if you have the sensor in the wheel, all you have to do is just claim the wheels are off another vehicle.
 
Most shops I am familiar with realize they can be held liable for not ensuring that TPMS sensors are operational. They know the vehicle has a TPMS by the year of the vehicle, the visual inspection of the tire valves and the warning light in the car. The system became mandatory for all vehicles built after September 1, 2007. The installer can refuse to install tires if the TPMS system is nonoperational. If they knowingly install them anyway they could be sued by the Federal Government. As I said, tire shops I frequent post this policy in their shop. No operational TPMS. No tires will be installed!
 
Thanks for the advice t-man. But, I prefer to purchase tires from places that do things properly. I don't really like the tire monitoring system but I have it and will maintain it as needed. I have no desire to start cutting up my wiring and lowering the value of my vehicle to get rid of a warning light.

Then why are you on this thread? The whole purpose is to get rid of that light for whatever reason. I personally have very large tires that I air down frequently and don't need an idiot light to tell me my tire is low. I also run tire beads and don't have to worry about wheel weights. So technically I can take my tires off the rim and put new ones on myself and never worry about a thing. I don't care about the "street cred" of a shop. Discount tire and other big names have some really stupid people working there that you are relying on to do the job correctly. Personally I have found the small mom and pop shops to be much more reliable which is what I use when needed. They also do offroad stuff and don't care that I don't want the idiot proof sensors, or the catalytic converters, or that my truck is lifted and one day will get a SAS with dana 60's. Does that make them bad? No, I'm just not feeding the Chinese, well maybe with the tires...

Can you support that? What is the federal statute number? Has the federal government filed such a suit?
 
Take it easy guys. You all can alter your cars anyway you want. I just thought some people on this forum might like to know what the requirements are for TPMS.

Here are some links to what I found on the law. Not sure if any lawsuits were filed but I will search and post if I find anything.

Here is the actual law.

And some discussion of the law:

This next link says you can essentially change your tires and rims and delete the the sensors but you can not disable the warning light on the dash. Go figure.

Fines are only against the installer, not the owner. I doubt any suits have been filed by the government. Would not worry about that.


Have fun!

The Final Word: NHTSA Clears the Air on TPMS Regs and Plus-Sizing Conundrum - Tire Review Magazine

As I read all of this, the CFR clearly indicates that an aftermarket installer cannot "make inoperative" the TPMS, but it in no way prohibits (or holds liable) an installer for installing tires on a disabled system.
 
Right!

NHTSA: “That is correct. After first retail sale of the vehicle, we do not believe that installing aftermarket tires and wheels necessarily makes the TPMS ‘inoperable.’ However, the MIL cannot be disabled. If the vehicle owner so desires, the vehicle could be taken to a dealer that has the replacement parts and tools necessary to repair and calibrate the TPMS system.”
 
Honestly, who gives a shit? It's my truck, if they don't like it, to bad, I'll go somewhere else. Since taking the tpms out and disabling the light nobody has said a word. Out of sight out of mind. The worst thing that can happen is they can refuse to change your tires. Their loss, there's over a dozen tire places in my town, all fighting for attention. One of them will do it.
 
I agree completely. I don't like the government trying to tell me that I'm too stupid to use a tire pressure gauge. My point is that, as far as I can tell from reading the CFR, a tire/wheel installer that tries to tell anyone that they can't install a new set of tires because I've disabled my TPMS indicator is blowing smoke ... there is nothing the in the CFR that indicates they would be held liable for installing tires on a vehicle with a disabled TPMS indicator. They just can't disable it themselves. For that they would be held liable.
