TPMS Issues After Wheel Swap - Toyota Yaris Forums

I have the 3 door hatchback. I looked all over the lower part of the dash and by the OBD2 port and I still can't find a reset button.

I did a little research on this yesterday and it suggests that the reset button simply tells the ECU to refresh and look for the existing TPMS ID's that are already stored. This button appears to only be present on older models (2011 and earlier) and is to be used after repairing a flat to reset the light. Here is the most notable source that I found: http://www.counterman.com/tpms-updat...nitor-systems/

It looks like I'll need to get a special scan tool to enter the new TPMS ID's into the computer. It's going for $150 on eBay. It's supposedly designed for my siutation and has a winter and summer setting where each of the ID's sets are stored.

The only problem is that you have to enter the new TPMS ID's manually. The TPMS ID's can be found on the sensors. So, take photos before you have the tires put on the rims. If you got used ones off of an old Yaris like I did, the seller has confirmed that you can use to tool to pull the ID's from the vehicle that the rims came off of. So, I won't have to break the bead of the tire to check.

I'm going to order one tonight and I'll post back next week to let everyone know if it works.
