Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Controlling The Functions Using The Steering Wheel Buttons
(S60 (11-), V60, XC60, V70 (08-), XC70 (08-), S80 (07-))
(V40 (13-))
The steering wheel buttons connected to the steering wheel module (SWM) (3/130) can be used to control:
- Volume control and CD track / radio selection
- Menu selection for traffic information
- volume control during hands free carphone calls and menu selection for the phone module (PHM) (16/60)
- volume control for Television Module (TVM) (16/36) (option)
- volume control for Rear seat entertainment module (RSE) (16/109) (only XC60) (option)
The signals from the steering wheel buttons are transmitted to the steering wheel module (SWM) (3/130) with LIN communication. The steering wheel module (SWM) transmits the signals on to the Infotainment Control Module (ICM) (3/281) using LIN communication. The infotainment control module (ICM) in turn transmits the signals on to the affected control module on the MOST network.
For more information, see appropriate Design and Function information for the Steering wheel module (SWM).
