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.
