Tire Pressure Sensor Registration

NOTE: When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized by the tire pressure monitor ECU prior to system initialization. To perform this procedure, a Toyota intelligent tester must be used. It is not necessary to register the sensor IDs when only tire rotation is performed.
NOTE: If transmitter IDs cannot be registered, the tire pressure monitor ECU is probably in initialization mode. Initialization mode can be terminated by making a short circuit between terminals No. 4 and 13 of the DLC3 connector (located under left side of instrument panel).
NOTE: Before beginning registration process on vehicles where tire pressure sensors have not been replaced, retrieve sensor transmitter IDs using intelligent tester 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.
NOTE: When system is in initialization mode after the reset switch has been operated, the registration is disabled until the initialization process is canceled or completed.
  1. Set the tire pressure of all wheels (including spare tire) to pressure specified on the tire and loading information label.
  2. Connect the intelligent tester to DLC3. See Fig 1.
  3. Turn the ignition switch to the ON position.
  4. Read and record the transmitter IDs (ID1 to ID5) by using the DATA LIST. See Fig 2.
  5. Input the transmitter IDs (ID1 to ID5) using the intelligent tester and transmit it to the tire pressure monitor ECU. See Fig 3.
  6. Select the "REGIST TIRE" mode.
  7. Select the "MAIN" registration mode.
  8. Set ID transmission condition to "COMPLETE".
    NOTE: The previously registered IDs will be deleted from the memory when the registration is completed.
    NOTE: If steps  48 are not completed within 5 minutes, the mode will return to the normal operation mode.
  9. When intelligent tester confirms that ID registration has successfully been completed, turn ignition switch to OFF position.
  10. Turn ignition switch to ON position. Select the "SIGNAL CHECK" mode on the intelligent tester.
  11. Confirm that the transmitter IDs and the tire pressure data is displayed for all 5 tires on the intelligent tester.
    NOTE: It may take up to one minute to update the tire pressure data.
    NOTE: If the IDs have not been registered, DTC C2171/71 is set in the tire pressure monitor ECU after about 30 minutes.
