Hyundai Tucson: Tire Pressure Monitoring System / TPMS Sensor Description and Operation
| 1. |
Mode
| (1) |
Configuration State
| A. |
All sensors should be in the Low Line (Base) state. |
| B. |
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
| A. |
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. |
| B. |
The LF command to this state must contain the sensors ID. |
|
| (3) |
Storage Auto State:
| A. |
This state is a Low current consumption state. |
| B. |
Sensors are in this state when they first arrive at the dealership (either on the vehicle or as replacement spares). |
| C. |
In this state, the sensor does not measure pressure / temperature / battery level. |
| D. |
The sensor will not transmit in this state unless requested to do so by the initiate command. |
|
| (4) |
Alert State:
| A. |
The sensor automatically enters this state if the measured
temperature exceeds 230 °F(110 °C) and over temperature shutdown is
likely. |
| B. |
In this state, pressure is measured every 4 seconds and RF data transmitted every 4 seconds. |
| C. |
The state lasts for 1 minute if it is pressure triggered. |
| D. |
This state is alse entered when a 3 psi change in pressure from the last RF transmission occurs. |
