TPMS Figure 2: Exploded view of tire pressure sensor. Figure 3: Installing tire pressure sensor. switch is turned to the OFF position during initialization. To initialize again, the tire pressure warning reset switch must be pressed again. 2. With the ignition switch OFF, connect the Techstream to the DLC3. 3. Turn the ignition switch to the ON position. 4. Enter the following menus: Chassis/Tire Pressure Monitor/Utility/ID Registration. NOTE: If this step is not completed within 30 seconds, registration mode will be canceled. 5. Perform the procedures displayed on the Techstream. NOTE: It may take about two to three minutes to update the tire pressure data. If the values are not displayed afer 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 afer three minutes or more. 6. Confirmation of transmitter ID registration: a. Enter the Techstream menu items in this order: Chassis/Tire Pressure Monitor/Data List. b. Confrm that the expected tire pressures of all tires are displayed on the screen. 1. Set the tire pressure of all wheels to the pressure specifed on the tire and loading information label. 2. Turn the ignition switch to the ON position. 3. Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks three times at onesecond intervals. 4. Connect the Toyota Techstream to the DLC3. 5. Enter the following menus: Chassis/ Tire Pressure Monitor/Data List. 6. Confrm that the expected tire pressure data of all tires are displayed on the Techstream screen in order to check the completion. NOTE: Initialization is normally completed within fve to six minutes. NOTE: If the initialization has not been completed successfully, DTC C2177/77 is set after the vehicle is driven for 20 minutes or more. NOTE: Te initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3. Tire pressure sensor registration NOTE: Before beginning the registration process on vehicles where tire pressure sensors have not been replaced, retrieve sensor transmiter ID(s) using the Techstream or by reading the ID on the tire pressure sensor. If the sensor is being replaced with a new one, make a note of the seven-digit number (transmiter ID) before installation, as it cannot be seen afer the sensor is installed (see Figure 1). 1. Set the tire pressure of all wheels to the pressure specifed on the tire and loading information label. www.moderntiredealer.com Demounting/mounting procedures CAUTION: The tire should be demounted from the wheel using the tire changer manufacturer's instructions. Use the following information to avoid damage during the demounting/mounting procedures. NOTE: The system will need to be initialized when tires are replaced with tires of diferent pressures; and tire pressure sensor and/or tire pressure monitor ECU are replaced. 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. See reset procedures. NOTE: If the negative batery terminal is disconnected, initialize the Power Window Control System afer the terminal is reconnected. Quik-Link: 800-687-1557 ext. 11138 65
