Hello all. I am looking to disable the tpms system on my 2007 Lexus Rx350. I check tire pressures weekly and dont want to deal with the light on in the dash. I have seen ways to do it on other Lexus vehicles but mine has different colors on the plug going into the tpms module. I have attatched a picture of the plug. Any help is greatly appreciated.

 

 

Did you ever figure out how to disable it?

 

Where did you find the module. Do you have a pic of the location of the module. From my understanding some has the blue and green wire connected to disable the light on the dash.

 

Did you accomplish the disable without removing the light bulb?

 

I would also like to know

 

You will need Techstream to correctly disable your TPMS. Cleanest way to do it. Or go to a Toyota dealer and have them do it, however since it is a safety item, they might say no.

 

So whats the story of which two wires need to be spiced together for the rx? Blue wire & ? one?

 

Bought 4 new sensors to have Discount tire to install w/ new tires.....One of the sensors was mispackaged, so they installed the three I had w/ a still good one that worked....whoa no more tpms light on & the new tires work great as well.......

 

I tried but was unsuccessful in my attempts to bypass the TPMS the conventional method (splicing the two wires). Unlike most of the other Toyotas, our cars use Canbus for the TPMS instead of a simple pink "IND" wire that goes right to the idiot light and will turn off with 5V. Lots of hours of reading various other wire diagrams and I have decided to give up on that method because it is testing my patience. The GS350 and IS350 seem to have the same situation going on as well.

I'll probably just find out which wire goes to the light into the dash itself and kill power there. Will post my findings.

 

Or just remove the bulb, Matt......Little more $, but I just replaced three of the sensors......

 

I think it may be an LED bulb, all of my old Highlander’s dashboard lights are so I bet the RX would be the same.

I would definitely consider the sensors if they weren’t so expensive, were serviceable and if I didn’t have to swap between two sets of rims/tires.
