This article I will share experience about how to erase transmitter ID2 code C2122 and add new TPMS sensor on Toyota Lexus or Scion.Help it helps!
What tools you need for erase transmitter ID2 code C2122?
After a quick look online, i get the software and USB adapter (it’s called mini vci) for usually under $30 shipped.
Don’t pay high insane dealer fees!! Also I have no idea how to do aftermarket TPMS sensors. I ONLY put OEM parts in my Toyota Vehicles. So I know there is some other weird programming you have to do with the aftermarket sensors.
I got this OEM Denso TPMS Sensor from Amazon.com for $35 shipped. MAKE SURE you know the CORRECT TPMS DENSO PART NUMBER for your vehicle!!! There are a few different ones this software will do ALL OEM sensors but you need to make sure you have the right sensor!!!
TPMS is not ON actually. Flashing means that i have an actual tire so it’s not that i have low tire even though i could have a low tire. It’s the fact, there must be something wrong with the TPMS.
Then go to the software Teachstream:
