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 (with CAN VIM) 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 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. See Fig 2.
- Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
- Connect the intelligent tester (with CAN VIM) to DLC3. See Fig 1.
- Turn the ignition switch to ON position.
- Read and record the transmitter IDs (ID1 to ID4) by using the DATA LIST. See Fig 2 and Fig 3 .
- Select the "REGIST TIRE" mode.
- Select the "MAIN" registration mode.
- Input the transmitter IDs (ID1 to ID4) using the intelligent tester and transmit it to the tire pressure monitor ECU.
- Set ID transmission condition to "SUCCEEDED".NOTE: The previously registered IDs will be deleted from the memory when the registration is completed.
- When intelligent tester confirms that ID registration has successfully been completed, turn ignition switch to OFF position.
- Turn ignition switch to ON position. Select the "SIGNAL CHECK" mode on the intelligent tester.
- Confirm that the transmitter IDs and the tire pressure data is displayed for all 4 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 60 minutes.
