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

Knocked this out using a blue ScotchLock - works like a charm.

Took me all of 15 minutes and no more annoying TPMS light!
 
Tpms

...... I have been checking my air pressure for 35 years without an ECM telling me I am low said:
I to have checked my pressures manually a long time before TPMS. However, one time the light came on while driving and probably saved me from buying a new tire. Sure wish replacements were less expensive.
 
That's way too complicated! All you need to do is unplug the cable from the TPMS receiver, stick a piece of wire into the connector to disable the warning lamp and ground the other end to the chassis. Then tape up the end and you are done!
 
On the 08 and newer, doesn't have the white/black wire as stated above. So I tried the pink/black wire and taped it to straight ground, no go on this mod. If any one has found the color codes or straight ground please post.
 
Didn't work, took awile for the light to come back on, still working on it. 08 t4r.

Edit: This did work on the 08, the connector moved around and didn't make a good contact. I moved it around and light went off, moved again and light came back on. SO good to go.


PINK W/ BLACK STRIP AND BLACK W/ RED STRIP WIRES.

Just did this today. First time since I purchased the vehicle that I haven't had the light on my dash. Dealership I bought it from installed all new sensors, but was still throwing a light on. I have checked my tire pressure for years, so this light is useless to me. Thanks for this!
 
Are there any negatives or downsides electrically to doing this? Does it add drain to the battery or generate extra current in places that don't normally get it?

On my first 04, brand new from dealer, had this light come on all the time even when enough pressure all around. They had to replace the TPMS module to correct the problem. After bringing in 3 times under 1000 miles.
 
Well apparently I don't need to do this mod afterall. I just ditched all the TPMS sensors (except the spare...haven't gotten a new tire for it yet) when I installed new tires and my TPMS light hasn't come on. It's been over 100 miles.
 
Give it a day there WXman, the monitor is probably still looking for them to compute the pressure. It will give up and the light will come on then. Mine did this when changing my rims.

This is why I did this mod, due to 2 sets of rims.

Possibly. But I did this on Friday. So I've driven the 4R for 3 days already and it's still not on. I think that's odd. Would be awesome if the ECU is smart enough to know that if ALL of the sensors disappear it was because the owner means for them to. We'll see..

Curious, when you say you ditched them, are you meaning thrown them away or are they still at your house/garage?

I know they have a battery in them. I think I seen where the light will come on when dead. Just curious, as stated, I have both sets of rims at my house and this light used to hesitate to come on for a day or 2, when I leave, ( non installed ones).

No, mine are gone. I sold them with the wheels to somebody else. I hope my TPMS light stays off. I'm curious about this too.
