2008 TPMS bypass

[Toyota Jim]

Since my google searches didn't come up with anything for 07 and up, and I was tired of my TPMS light being on, I got to work. I figured I'd share what I did on my 4Runner to see if it helps anyone else. Obviously try at your own risk, I accept no responsibility... blah, blah, blah.

Here's the wiring diagram. The pink/black is still the TPMS light wire (pin 5). The black/red is the 12v IGN source into the TPMS module (pin 7).

I cut the pink/black wire and connected the harness end to the black/red wire. Basically, I'm putting 12v on either side of the dash light, so it can't complete the circuit and light up.

This instantly turned off the flashing light on the dash for me. I haven't noticed any negative effects from doing this, nor should it drain the battery, because it's an IGN hot.

I hope this helps!

Wouldn't it have been easier to just pull the bulb out of the dash? Or cut the power wire going to the bulb so it doesn't see power at all?

One screw compared to pulling the instrument cluster out? I think this was easier.

Just not a fan if twisting wires together like that. You would likely have had the same result by just cutting the feed wire to the bulb, no? That or buying new TPMS sensors of course.

New TPMS wasn't in the cards. I also soldered this before I taped it up. Sorry I didn't explain that.

There's nothing wrong with the connection and I get the cost of TPMS sensors can be insane unless you find a deal on ebay or something. You said you're sending power to both legs of the bulb. If you were to just cut the one wire that powers the bulb and not splice into anything else, wouldn't that shut the light off also?

 

[Toyota Jim]

Yes it would. However, one screw under the glove box was an easier option than chasing a harness behind the instrument cluster.

PSI/temp data is available off the sensors. Data can be viewed from an ....(eg. Pioneer NEX with idatalink Maestro)

That write up I found, but it doesn't work on my truck.

Followed Toyota Jim's directions above on an '08 Sport and so far it's worked like a charm. New SCS Ray 10's on the UPS truck for delivery today. No need for TPMS sensors when I have them mounted.

Nice, thanks for sharing!

 

[Toyota Jim]

Glad it works for you guys!

 

[SummitRunner]

Thanks, I'll have to try this soon

So.... You just took ground away from the bulb?

And the computer does not care about the tpms?

It only activates the dash bulb? Not a check engine light or anything?

Correct.

here is an easy way with NO WIRE CUTTING

MAKE A NOTE AND LEAVE IN YOUR OWNERS MANUAL THAT YOU DID THE MOD FOR FUTURE OWNERS.
I will change my tire sensors when i get my next set of tires....until then this was my fix.

CHECK PRESSURE OFTEN!

here I bypassed my sons 2007 4 runner.... the board is under the cover plate that mounts under the glove box.

Here is the module with the cable un plugged


here you can see how the clip holds the circuit board into the housing.

here the pins (they are different for the GEN 5).... its a 16 pin card (gen 5 are 12 pin so the jumpers they are different!!!!)

Here you can see below how I added a jumper on the circuit board corresponding to the pink black and the white black wires

(here is the jumper)

This worked today on 09 SR5 for me! One modification, Didn’t clip Pink Black. Just jumped PinkBlack to RedBlack with 3M Scotchlok and left PinkBlack connect to pin connector.

I need to definately try this on my son's 05. I am sick of the tpms light. I have installed and programmed 5 new sensors- spare included. They worked great and then started acting up- tpms light flashing and then went solid. I checked and pressures were fine in all 5 tires. Replaced sensors with schrader ez sensors this time. Programmed and relearned and all was good for 2 days. Tires of messing with it.

Correct.

Would this also work for 2004 ?

Careful, ive seen it mentioned with:

pink/blk & white/blk
pink/blk & blk/red

Ive seen a video with pink/blk & white/blk, and then ive seen schematics with pink/blk & blk/red

According to the schematics on Page 1, why couldnt you simply cut the pink/blk wire and be done with it?
