Hyundai Accent (HC) (2017 - 2022) Service Manual: TPMS Sensor

- Description 1.General descriptionWU 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.

Hyundai Accent (HC) (2017 - 2022) Service Manual: MDPS Assembly

- Removal 1.Disconnect the battery negative cable and wait for at least three minutes before beginning work. 2.Put a flat tool (Ø4mm) into a guide hole located in the bottom of steering wheel and press a spring.     • When put a tool into a hole, make sure not to damage an airbag cusion by a tool. 3.Turn a steering wheel anti-clockwise, so make a guide hole (A) shown on the rightside.
