Disable TPMS

To each their own, some love them, some hate them. Some hate the light on the dash,
others don't mind it being on. I guess the final
straw for me was when I swapped my winter tires back to the summer tires and I had to get the sensors re-entered onto the system (because they only can stores 4 tpms sensors) and the TOYOTA dealer couldn't get the system to re-accept the sensor codes..... all sensors were alive and had good batteries but after 1 hr they suggested 4 new sensors yet my were alive and recognized by the scan tool. I said you know I'm good we will just leave it as is. They were good about it and never charged me. That's when I decided this system is not for me. I regularly check my tires air, so I am fine without it. But I am glad you like having them. Cheers !

 

I check my tire pressure one a week and do a visual check every time before I get in the truck. It doesn’t take long and I don’t miss the damn tpms light.

 

I appreciate everyone on this forum and the knowledge they share did this mod about 6 months ago to get rid of the annoying light, I do check my tires regularly anyway. But now I have a new issue. The mod worked perfectly for 6 months but now while accelerating the tpms light flashes ‍♂️. Only does this under acceleration, taking off or climbing a hill. Anyone have any ideas? Just checked my splices and they are still connected.

 

Wow, that's interesting???? I have not encountered this... Given it was working fine, I would think it's a loose connection, I know you said you checked them but the wires are so fine and if you used a connector that pierces the wire there may be intermittent loss of power. I know one member had a terrible time getting the wire pierced and a good connection. I would start there again. If using positaps, maybe scrape the casing off a bit to get a good connection. I hope this works out for you.

 

Mine came on again after a few months. I went back and pressed down on the T tape connecter and light has never came back on. Check your connections.

 

The T taps in my opinion are not a good connection method. I would consider Posi-taps as an alternative

 

Agreed. I had the t taps in the garage so ended up using them. Light hasn’t been back in almost a year.

 

Another approach you may want to consider, when I did mine the wire was so fine on the end of the positap that you feed the wire into and use the screw connection (the non piercing end) might be a bit loose and not making connection. I used 2 positaps and used a heavier guage between the 2 positaps. Basically I used the piercing end on the 2 wires. So I pierced the light green and the yellow cause when I tried to put the light green into the positap it would pull out. The good part I found, was yiu could prepare all this on the work bench then it's a case of just piercing 2 wires under the dash instead of trying to screw the light green one in with my old fat fingers . Lol

 

So I I took it all apart and redid the connections and it seems to be fixed. I guess the taps were in there good enough for a while but had become a little loose . Thanks for the help!!

 

Yes, I realized this (i.e. having to reregister the sensors through the ECU) after laying out $2K for summer wheels/tires with new sensors. Once I realized it was going to cost 2 x $50 per year (i.e. spring/fall swap), I said screw that and put a piece of black electrical tape over the dash low-pressure light. ;-)

 

I'm glad it all worked out for you !!! Cheers

 

This is my introductory post (drawn here by this thread):

No stranger to Toyotas: Today I own four, having yesterday bought a 2008 Tundra Double Cab Limited 4x4 5.7 Liter.

This Tundra comes to me with 100K of extended warranty service receipts which I studied last night:
The water pump (16100-09491) had to be replaced at 57,708 miles. Apparently, it's a common problem.
At the same service, there was one Recall and one Special Service Campaign (SSC) remedy:
Recall was for the Power Window Master Switch (PWMS) assembly (driver door): They greased the wire contacts at all passenger switches to prevent overheating and fire;
SSC remedy was a bracket/plate added under the accelerator pedal to prevent interference with the floor mats (which were a dealer installed option at purchase). An SSC sticker was placed under the hood at completion.

It's the newest vehicle I've ever owned and I like it! The dealer installed options make an impression: TRD big brakes, TRD dual exhaust and TRD cold air intake.

But, there's this cursed / possessed ugly step sister inherited with them: The TPMS light.

I've perused every post in this thread, which contains all I hoped to learn (and more):

1) No wonder a newer vehicle costs so much;
2) TPMS might be nice, if/when it works as intended;
3) As implemented, TPMS fails my cost / benefit analysis.

No reason to cut the harness: When a TPMS receiver/antenna (89760-0C010) is sourced, plug it in and flip the switch. (Neighbor is a Tech at Toyota and we're 22RE comrades.)

I despise Scotchlok splices: the dealer used them when adding the optional trailer brake controller at #26 miles. I intend to repair this asap.

The temporary fix tomorrow will be a Scotchlok between #5 (LtG) and #6 (Y +5V) at the TPMS ECU plug, to be replaced with 2 soldered wires and a mounted switch when weather allows.

NOTE:
If I ever see this light again in my 2005 Corolla XRS, I will also disable / switch it -- likely a pink wire to snip / ground out. (I have the #3 volume TSRM for this vehicle, which will help)
2005 is prior to the 2007 federal mandate for TPMS. There are no TPMS sensors in the original wheels or my Enkei RPF1 wheels - I mounted the tires myself.
The new tires (195/55R16) are a bit larger than stock (about 1.5%, I recall) and this may have confused this simpler TPMS.
Happily, the 'TPMS reset' procedure worked, once I found it at page umpteen-thousand in the TSRM. I have no warning indicator (x2 months).

 

Welcome to the forum, lots of details that will surely help others. Enjoy the truck they are fantastic

 

Thankx, Trxtr.
Pulled the glovebox, stripped the wire shielding of #5 and #6, and tied 'em together with a stripped length of #16ga. Temporary but...
Happy dash with no light on the way to work this morning!

 

That's great !!! Enjoy that light being turned off. I do not regret it one bit. Many thanks to the others who have helped along the way with this issue, just proves that we can help each other out with these issues. Cheers !

 

I think you will appreciate my resolution / modification of the TPMS warning light problem:

PICs tell it. Here's the description:

1) Buy an ON/OFF (locking type - not momentary) push button switch with lighted ring;
1)a) For this PIELE switch (black shell w/ yellow light ring) drill a 1/2" (12mm) hole in the top of the upper glove box (at the 'third rib from the right' - so it fits right of the pass air bag and left of the harness);
2) Despite the wiring instructions included:
2)a) The blue wires are ON/OFF via the switch - at the TPMS computer: one goes to #6 (yellow 5V) and the other to #5 (light green) -- no need to cut either wire, just strip the shielding;
2)b) The Red/Black wires are the light, which I tapped into the lower glovebox light circuit;

Now, you can defeat the TPMS light at will with the switch and the dash colored light illuminates with the parking lights!

PIC 1 = where I tapped into TPMS wires
PIC 2 = looking up at the glove light harness - the orange #20ga wires going left are for another switch I will install near the RSCA button
The original owner installed an ugly giant toggle that manually turns on the reverse lights no matter anything - a good idea when trying to hook up a trailer at night, though poorly executed
PIC 3 = the end result in upper glove box

Could be better: Add a 4-pin plug so you can remove the upper glove in the future; my wires are soldered for the present.

 

Wow, another creative solution !! Thanks

 

What have you done to your 2nd gen Tundra today?

What I did to my 2nd Gen Tundra today: Got help from my neighbor, a Toyota Service Tech. (The read might be helpful here)

 

Found a TPMS Receiver/Antenna (89760-08010) at the wrecker for $5! Hope it's functional 'cause I'd like to accessorize with the difference between that and a new one.
In a Sienna, it's above the steering wheel. Pic/discussion posted here: https://www.tundras.com/threads/wha...2nd-gen-tundra-today.68/page-506#post-3416397

 

Worked like a charm! Bought the truck a month ago and that blinking light has been driving me nuts!! Thanks for this one!!

 

There is a drawback... Remember to check your tires for low pressure before you get in to drive your Tundra.

Bought mine a month ago also. You having as much fun as I am?

 

I live out into he sticks and have been on and off jobs sites for my whole life. So it's a requirement to check tires! Lol! That's why I don't really care about the sensors. I've wanted a tundra forever and just bought this '06 a month ago. Haven't had any fun with it, cause I'm working on figuring out my 4wd not working. I love the truck, but need this 4wd to work. Plan on posting what I find when it's fixed, cause I know this is a frequent question.

 

Awesome,
Glad you were able to beat it.

 

When It came on in my wife's Lexus, she called and said "what's the light that looks like parentheses" mean?

 

Bought a TPMS Programming Tool (

$264 Autel MaxiTPMS TS508WF TPMS Relearn Tool, 2024 Upgraded of TS508/TS408, Activate/Relearn/Reset All Sensors, One-Click TPMS Health Check, Program MX-Sensors (315/433 MHz), Read/Clear TPMS DTCs

Autel MaxiTPMS TS508WF - Kit with TPMS sensors).
The other day, I finally installed the TPMS Receiver/Antenna (89760-08010) obtained from the wrecker in December.
NOTE: The brackets are reversed and Sienna's is wider - swap the cover over with a torx bit and good to go.
Yesterday, I had the new sensors fitted and - presuming the used Receiver is good - it remains only to program them to the truck and turn on the 'warning light override' button installed earlier.
