This is how I disabled the TPMS on my 2009 Rav4. Special thanks to CTScott from YarisWorld:
DIY - Bypassing Tire Pressure Warning System (TPWS / TPMS) - Page 3 - Toyota Yaris Forums - Ultimate Yaris Enthusiast Site

Its about a 15 minute job without a switch, 20 minute job with a switch.

Tools required:
- Wire cutter
- Electrical tape (or tap wire connectors)
- 16+ gauge wire (optional)
- Bipolar switch (optional)

The TPMS is located behind the passenger glove compartment. You dont have to remove the glove compartment. There is a black panel that easily comes off below the glove compartment. (Directly above the floor mat). Two clips hold it in place. Just press and pull, no tools necessary. Remove the panel and you will see the TPMS device directly above it:


This is what it looked like on my vehicle:


Here is what the connector looked like:








Cut the pink wire from pin #5 and connect the end coming from the vehicle to the red wire in pin #6. Note that the pink wire coming out of the TPMS device is left unconnected.

If using a switch, install switch as diagramed below:


If you want to test the voltage readings here is what I was getting:
Red Wire 6+ volts
Pink Wire 4-8 volts - when TPMS sensors is active on the vehicle
Pink Wire 0 volts - when TPMS sensors are removed from the vehicle

ECU will illuminate the TPMS dashboard light when the Pink Wire reads 0 Volts.


TPMS light illuminated on my dashboard:


TPMS light off 15 minutes later after running this procedure:






Section below is OPTIONAL

Some of the Yaris members took this step a bit further and made the connection within the TPMS device itself (no wire cutting but soldering required).


Another Yaris member made a fancy switch like this:




Just remember to connect the Pink wire to the Red wire!

Nice write-up, solidfish! I especially like that switch mounted in the ecu. Very stealthy!

I also should note that this procedure can be done when the TPMS light is on or off. Regardless of the initial state, this procedure will permanently keep the light off. (unless you do the switch)

Solidfish, very nicely done!

James, can this be made into a sticky or put into a DIY library?

Very nice job. I agree it should be a sticky so whenever I need it, it will be handy. (it's all about me right?) :p
Great idea, I will move it to the Interior forum, and make it a sticky.

just did the 'no-switch' method on my 2006 and the darn TPMS light is finally off!! took me about 10minutes as I also had to remove the black tape from inside the guage cluster. Thank you Thank you!!!

Great! Glad it worked for you. It does feel a lot better without that annoying flashing light!

Wiring Differences

I noticed from the first post that the wiring was for a 2009. I was all set to do a 'switched" mod on my 2006 RAV but the wiring was not quite the same.
Pink is in pin 4, not 5
Green is in pin 5
Red is in pin 6
Is the important wire the pink one?

As a stop-gap, I taped over the TPMS light.

Any advice would be appreciated.

Thanks!:thumbs_up:

The pink wire goes to the LED in the instrument cluster. The red wire should have +5 volts on it. You want to tie the pink wire to the 5 volt line.

Really dumb question.... What would be the reason for disabling the system? Sorry, this is the first car I have ever had with a tire monitoring system. :oops:

How did I ever drive the last 30 years without it??? Oh, that's right, I checked my tire pressures at regular intervals.:wall

It's not a dumb question at all, Dean. For folks like us who live in the South, it doesn't seem to make sense to disable the TPMS. But up in the frozen Nawth, where you may have to switch to snow tires every Winter, the TPMS can be a real PITA! :wall With 2 sets of tires and rims, only one set at a time can be programmed into the system. So while you're riding around on your Summer wheels, everything works fine. But when you change to your Winter wheels, you end up with an annoying TPMS light all the time.

Unless you are independently wealthy and can afford a second set of TPMS sensors for the second set of rims, so you wouldn't really notice any difference. So this is a short cut for us Po folks. ;)

Yup, this is what I'll be doing come Nov-Dec or even earlier while the weather is still nice to play in the car with wiring....

This is great info. I've gotten along fine without tire pressure sensors for 44 years and it is great to see a way to work around this profit center add on. Thank You All!
