TIRE PRESSURE WARNING SYSTEM INITIALIZATION

Note


  • Initialization can be confirmed through the tire pressure warning light.

  • The order in which the data is received is random.

  • If the signals from all the wheels are received, initialization is completed.

  • Initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures Click here.

  • Initialization is normally completed within a few minutes.

  • It may take up to a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 Click here.

  • If initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 37 km/h (23 mph) or more continues for 20 minutes or more.

  • During test mode (signal check mode), the system will not change to initialization mode even if the initialization procedure is performed.

  • When answer-back is displayed for the ID switching function, the system will not change to initialization mode even if the initialization procedure is performed.
