Toyota Tacoma 2015-2018 Service Manual: Initialization



  • Initialization can only be performed for vehicles with a tire pressure warning reset switch.
  • If initialization is performed, the existing tire positions will be cleared, but will be automatically identified when the vehicle is driven at 37 km/h (23 mph) or more for 10 minutes or more.
  • 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 tire pressure warning valve and transmitters are received, initialization is completed.
  • Initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures (See page Initialization is normally completed within a few minutes. ).
  • Initialization is normally completed within a few minutes.
  • It may take 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 (See page If initialization has not been completed successfully, DTC C2177/77 ).
  • If initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 37 km/h (23 mph) or more is detected for 20 minutes or more.
  • During test mode (sensor check mode), the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.
  • Initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3. Illustration Text in Illustration
