Title: TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: INITIALIZATION; 2016 - 2020 MY Sienna [12/2015 - ] |
INITIALIZATION
NOTICE:
-
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 (See page
).
-
Initialization is normally completed within 5 or 6 minutes.
-
It may take up to 5 or 6 minutes until the values are displayed. If the values are not displayed after several 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 8 km/h (5 mph) or more continues 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.
