Tire Pressure Sensor Registration: Notes
NOTE:
When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized (registered) by the tire pressure monitor ECU prior to system initialization. To perform this procedure, a Toyota Techstream must be used. It is not necessary to register the sensor ID(s) when only tire rotation is performed.
NOTE:
Before beginning registration process on vehicles where tire pressure sensors have not been replaced, retrieve sensor transmitter ID(s) using Techstream or by reading the ID on the tire pressure sensor. If sensor is being replaced with a new one, make a note of the 7-digit number (transmitter ID) before installation, as it cannot be seen after sensor is installed. See Figure.
