I was looking through the service manual today and apparantly there is a tire pressure diagnostic port somewhere in the vehicle, but it doesn't say where. By activation the diagnostic mode the tire pressure light will blink X amount of times to indicate which tire is low. Anyone have any clue where this harness is?

 

Did you find out about this? And how do I get that beep beep module?

 

I want to know about the TPS diagnostic aswell if anyone knows...

 

Yes, I actually did figure this out.

On my '04' there is a small plastic knock out near the hood pop. I popped the knock out out and behind it there was a small two pin white connector. I actually removed my whole lower dash, because it the harness was taped around a bundle of wires, but it can most likely be accessed without dropping the panel.

There is actaully only one wire in the connector. I grabbed a push button switch and put one side in to the connector, and I grounded the other side.

Then, you have to hold the button down for ~10 seconds and then let it go. Wait a few seconds and the light will turn off, and then it will blink X amount of times to indicate which tire is low. 1 flash is front left, but I forget the other ones (it is in the service manual). Kind of a neat little feature, especially if you live where the weather changes drastically and your light turns on a lot.

 

So this was on the inside of the car? Can you take a pic of where it was?

 

I just want a way to disable the TPMS light. Any ideas? Thanks

 

Make sure each tire has above 30psi of air in it!!!!



I was hoping there would be a way through the diag port to disable the light, but I couldn't find one.

 

Hows the beep module coming along KPierson? Any idea how much it will cost?

 

Awesome find, really appreciate all the tech info. I’m a dork so I love this stuff.

 

for the record...(and for those of you too lazy to look in the manual lol)

 

is that only the 06 nav screen?

 

It's def not on the '04 screen.
