Tire Pressure Sensor: Description and Operation
TPMS SENSOR
DESCRIPTION
DESCRIPTION
1. MODE
1) Configuration State
^
All sensors should be in the Low Line (Base) state.
^
In Low Line (Base) configuration, sensor transmissions occur every 3 minutes 20 seconds (nominal) and pressure is measured every 20
seconds.
2) Normal Fixed Base State
^
Sensor transmissions continue at the Low Line (Base) configuration defined rates until the state is either changed by LF command or by the
sensor detecting a condition that requires a temporary change to another state.
^
The LF command to this state must contain the sensors ID.
3) Storage Base State:
^
This state is a Low current consumption state.
^
Sensors are in this state when they first arrive at the dealership (either on the vehicle or as replacement spares).
^
In this state, the sensor does not measure pressure/temperature/battery level.
^
The sensor will not transmit in this state unless requested to do so by the initiate command.
4) Alert State:
^
The sensor automatically enters this state if the measured temperature exceeds 230°F (110°C) and over temperature shutdown is likely.
^
In this state, pressure is measured every 4 seconds and RF data transmitted every 4 seconds.
^
The state lasts for 1 minute if it is pressure triggered.
^
After state is also entered when a 3 psi change in pressure from the last RF transmission occurs.
