Toyota Tacoma (2015-2018) Service Manual / Tire And Wheel / Tire Pressure Warning System / Initialization

INITIALIZATION

NOTICE:

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.
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 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. Text in Illustration
