Initializing Tire Pressure Monitor System
NOTE:
It is necessary to register the transmitter ID in the tire pressure warning ECU, prior to initialization, when replacing the tire pressure sensor and/or tire pressure warning ECU. See TIRE PRESSURE SENSOR REGISTRATION .
NOTE:
Initialization is normally completed within 5 to 6 minutes. If the initialization has not been completed successfully, DTC C2177/77 is set after the vehicle is driven for 20 minutes or more.
NOTE:
Initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3. See Fig 2.
- Set the tire pressure of all tires to the specified value(s).
- Turn the ignition switch to ON.
- Press and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times. With the ignition switch ON, wait for approximately 5 minutes.NOTE: For this vehicle, it may take longer than usual to receive data from the tire pressure warning valve and transmitter while the Data List is displayed. Therefore, before displaying the Data List, wait approximately 5 minutes to receive data from the tire pressure warning valve and transmitter.
- Turn the ignition switch OFF.
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON, then the Techstream ON.
- Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
- Confirm that the expected tire pressure data of all tires are displayed on the Techstream screen.
- The initialization is complete when the Data List "ID Tire Inflation Pressure" display shows the correct pressures.NOTE: It may take up to about 5 to 6 minutes to update the tire pressure data. If the values are not displayed after about 5 to 6 minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24.
