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. See Fig 1.
- 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.
