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 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 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 8-digit number (transmitter ID) before installation, as it cannot be seen after sensor is installed.
- 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.
- Select the "REGIST TIRE" mode (UTILITY - REGIST TIRE).
- Input the transmitter ID(s) (ID1 to ID4), using the intelligent tester, and transmit them to the tire pressure warning ECU. See Fig 2 and Fig 3 .
- Set the ID transmission condition to "ID REGISTRATION COMPLETE".NOTE: Any previously registered ID(s) will be deleted from the memory when the registration is completed.
- Turn ignition switch to OFF position.
- Turn ignition switch to ON position. Select the "TIRE PRESS" mode on the intelligent tester.
- Confirm that the tire pressure data is displayed for all 4 tires on the intelligent tester. This will confirm that the registration has been completed successfully.NOTE: It may take 5 - 6 minutes to update the tire pressure data.NOTE: If the ID(s) have not been registered, DTC C2171/71 is set in the tire pressure monitor ECU after about 3 minutes.
