DIY - Bypassing Tire Pressure Warning System (TPWS / TPMS) - Page 6 - Toyota Yaris Forums

Ok so a few days ago I did this. I added a switch. And it worked perfect for a few days. But now the light flashes and when I turn the switch off is stays on (doesn't flash).

Measure the voltage on the brown wire.

I'm not getting any voltage off the brown, white, or red wire, where is the fuse for this thing?

It's the ECU-IG 10A fuse.

In the fuse panel that faces the driver's side floor mat at the bottom left of the dash.

You're looking in the wrong place. Lay on the floor and look up at the bottom of the dash (directly under where you are looking). You'll see a plastic panel with the fuse locations. Pull that plastic cover off and the fuses will be visible.

found it thanks a bunch

but now when I turn my headlights on the instrument panel goes dim, under daytime running lights the dash is illuminated, very odd and can't find anything in the owners manual.

That's the normal behavior for the instrument panel lighting - Full bright with headlights off and dimmed, per the knob, with headlights on.

Your Yaris has daytime running lights?

yes 09, found it was just the dimmer switch turned off, for some reason the dimmer switch dims the dash only when the headlihts are on.

My '07 & 2 '09s have normal headlights that you have to turn on, no DRLs. (Thankfully!) Must be a state law thing.
