DIY - Bypassing Tire Pressure Warning System (TPWS / TPMS)

[tradergordo]

I did this fix on a 2010 Yaris and it worked perfectly, so thanks a lot! But now I want to do the same on a 2014 Yaris (4 door hatchback) but I don't see the TPMS ECU behind the glove box. Does anyone know where it is? I couldn't find any free repair manuals online like there are for older models, cheapest one on eBay is $60...

There is not a simple solution for 3rd gen (2012+), as the TPMS ECU now sends the info to the cluster via CAN bus message, rather than by a simple single line driving an LED.

The third gens do allow you to easily relearn the TPMS sensors by simply pressing a button, so the simplest solution is to have a second set of sensors in your alternate rims.
