Hyundai Sonata LF: Tire Pressure Monitoring System / Description and Operation
The Tire Pressure Monitoring System (TPMS) monitors the
pressure and temperature inside the tire in order to warn the driver of
changes in pressure which may influence the operation of the vehicle.
The TPMS control module analyzes wireless information fro
In other words, the system detects the pneumatic pressure of
the tires and warns the driver of if the pneumatic pressure drops below
the standard level.

Lamp ON/OFF Conditions when the Tire Pressure Decreases or Air is Leaking from the Tire
| 1. |
Lamp ON
| A. |
The lamp turns ON when the tire pressure decreases below the standard level. |
|
| 2. |
Lamp OFF
| A. |
Low pneumatic pressure: The warning lamp turns OFF when the tire pressure exceeds the pressure required to turn off the lamp. |
|
TPMS Fault Warning Lamp
| 1. |
Warning Conditions and Display
| A. |
When the system detects a defect in the external operating
environment (low battery voltage, abnormal vehicle speed, etc), the
warning lamp blinks for about 1 minute and then turns ON. |
|
| 2. |
Lamp OFF
| A. |
The warning lamp turns OFF when the DTC is resolved. The DTC
is automatically resolved when the system does not receive any fault
signals for 30 or more ignition cycles after it changes to the previous
fault code. |
| • |
If this phenomenon occurs while driving, you should check the cause of the fault even after the DTC is resolved.
(Turn the ignition switch from OFF to ON. Then, check the lamp status.) |
| • |
The warning lamp turns off once the DTC is resolved. The
warning lamp stays on until you complete the check necessary to resolve
the DTC. |
| • |
If the DTC is resolved, the warning lamp turns OFF during the same ignition cycle. |

Certain defects are not diagnosed as DTCs. |
The following are major defects:
| A. |
In order to diagnose more symptoms of the fault when the
ignition line malfunctions, you must check the warning lamp when you
turn the ignition on. |
