Hyundai Elantra: Tire Pressure Monitoring System / TPMS Receiver
Description and operation
TPMS Receiver : BCM(body control module) integrated management

1. | Early state •
| Platform information and sensor ID are not input. |
|
2. | Normal State •
| To detect tire air pressure and DTC, the receiver must be in normal operation. |
•
| The receiver can check the position and information of the sensor. |
|
1. | General Function •
| Auto-learn takes place only once per Ignition cycle. |
•
| After this process is successfully completed, it is input into four sensor ID storage devices. |
•
| Until the end of automatic learning, if there is a drop in air pressure and air leakage, the previously learned sensor and each wheel position are detected. |
•
| Preliminary tire expansion and DTC status are not indicated. |
|
2. | General Conditions to Learn New Sensors •
| Automatic learning works only when the speed is over 15.5 mph (25 kph). |
•
| Typical time at driving continuously over 15.5 mph(25 kph) to learn a new sensor is up to 10 minutes. |
|
3. | General Conditions to Un-Learn a sensor that is removed •
| It takes less than 10 minutes at 15.5 mph(20-30 kph). |
•
| It depends on the speed of the vehicle and the number of sensors input to the receiver. |
