Hyundai Kona (OS) 2018-2021 Service Manual / Suspension System (NON-ECS) / Tire Pressure Monitoring System / TPMS Sensor Description and operation

Description

General description

WU is a sensor placed in the tire that reports pressure and temperature.

The WU is mounted inside the wheels, fixed to the valve. The angle between the valve and the housing of the WU is variable.

This allows adaptation to various types of rims.

The Wheel Unit is made of a PCB supporting the electronic hardware and encapsulated inside a housing which is potted with polyurethane.

It is self-powered by a battery and includes all systems for parameter measurement (pressure, temperature and centrifugal acceleration and optionally rotation direction), RF transmission and LF detection.

To achieve the specified battery lifetime, the WU supports various measurement and transmission timings, depending on WU operation mode.

For RF transmission, WU uses an internal antenna.

2.	First Block Mode : When vehicle start driving, Sensor enter Mode First Block. Typical period of RF emissions is 16 sec. for 40 times for Auto-learning and Auto-location function.

3.	Driving Mode : After 19 min. parking and then finishing Mode First Block mode, WU enter Driving mode. Typical period of RF emissions are 64 sec above 4g vehicle speed.

4.	Parking Mode : at below 3g Vehicle speed, enter Parking mode. Typical periodicities of RF emissions are 13 hours.
