TPMS diagnostic information – Toyota Prius, Prius C, Prius V 2006-2019
After the TREAD Act was mandated in 2007, all vehicles manufactured in the United States beginning in 2008, must be installed with direct or indirect TPMS systems. The Toyota Prius is installed with a direct TPMS system, which means there are TPMS sensors in the wheel.
When services are performed, such as a tire change or TPMS sensor replacement, in one or more tires of a Toyota Prius, a TPMS relearn is recommended to transfer the sensor information to the vehicle’s ECU.

Before you begin:
Be sure to have the TPMS sensor ID information for the sensors in the wheels that are not currently registered with the vehicle. Use a TPMS activation or trigger tool that displays the sensor ID’s on the screen, such as a VT31 or VT36 to read the TPMS sensor ID’s, then be sure to write them down.
Next, make sure the ATQuickset software is installed on your PC. Connect the tool to your PC using the USB cable that comes with the kit.
Some Toyota models have a “SET” or “TPMS RESET” button, which is located below the steering wheel or under the glovebox. When the button is pressed, the system tries to locate the sensor ID’s that are already stored. The “SET button” can be used when performing a tire rotation that has different tire pressures in the front and rear, changing or adjusting the tire pressure, or changing tire size, or when tires are replaced.
If the “SET” button is pushed after new sensor IDs are introduced and before a relearn is performed, the ECU must be unlocked in order for the relearn procedure to work correctly. Some advanced TPMS scan tools have the capability to unlock the ECU. If your TPMS scan tool has the “UNLOCK ECU” option, the relearn procedure can be properly performed.
Use the VT56 to retrieve Toyota TPMS DTC codes by selecting the “Service” icon. After selecting the Make, Model, and Year, select the DTC code icon. Use the OBDII module to retrieve the Toyota DTC TPMS information to diagnose and service the TPMS issues determined.
