DESCRIPTION
-
During driving, the BCM receives the signal transmitted from the tire pressure sensor installed in each wheel. The BCM of this system has pressure judgment and trouble diagnosis functions. When the TPMS (Tire Pressure Monitoring System) detects low inflation pressure or another unusual symptom, the low tire pressure warning lamp in the combination meter turns ON.
-
Tire pressure varies as per the change in tire temperature. Therefore, warning tire pressure value is varied as per the change in tire temperature.
-
If the tire pressure is less than the warning tire pressure value, the low tire pressure warning lamp illuminates.
-
Location of the wheel is specified due to the synchronism of the wheel sensor position and tire pressure sensor position.
-
Activates TPMS when the Nissan Sentra vehicle speed is 25 MPH (40 km/h) or more.
-
TPMS has Easy Fill Tire Alert function to aid in tire inflation. Refer to System Description.
LOW TIRE PRESSURE WARNING LAMP INDICATION CONDITION
