Tire Pressure Sensor Registration

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. To perform this procedure, a Toyota Techstream must be used. It is not necessary to register the sensor IDs when only tire rotation is performed.

NOTE: Before beginning registration process on vehicles where tire pressure sensors have not been replaced, retrieve sensor transmitter IDs 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.

Set the tire pressure of all wheels (including spare tire) to pressure specified on the tire and loading information label.
With the ignition OFF, connect the Techstream to DLC3.
Turn the ignition switch to ON position.
Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.
Perform the procedures displayed on the screen.
Confirmation of transmitter ID registration:
1. Enter the Techstream menu items in this order: Chassis / Tire Pressure Monitor / Data List.
2. Confirm that the expected tire pressures of all tires are displayed on the screen.
NOTE: It may take up to about 2 to 3 minutes to update the tire pressure data. If the values are not displayed after several minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24. If the IDs have not been registered, DTC C2171/71 is set after 3 minutes or more.
