Steering wheel switch module

The steering wheel switch module is a single unit that includes the following components:

• the combination switch holder (1),
• the clock spring (2),
• the wiper switch (3),
• the audio system control (4) (depending on version),
• the cruise control switch (5) (depending on version),
• The lighting switch (6).

The steering wheel switch module provides the human-machine interface for the radio, cruise control, wiper and lighting controls.

The steering wheel switch module transmits the user's actions to the BSI via the VAN CAR 1 multiplexed network.

The steering wheel switch module also performs the following functions:

• controlling the buzzer integrated in the instrument cluster housing according to sound requests sent by the BSI,
• receiving RF messages from the plip and the tire underinflation transmitters,
• communicating with the transponder for the coded immobilizer,
• relaying information from the steering wheel angle sensor.
