General Information - MULTIFUNCTION Steering Wheel

WARNING: This page is about a different variant/trim than selected.

Buttons are integrated in the steering wheel for easier operation of Infotainment, telephone and the navigation system. On Tiptronic, rocker switches are also installed on the Left & Right.

The Multifunction Steering Wheel Control Module -J453- (in the right button) reads out the button information and transfers them over the LIN bus to the Steering Column Electronics Control Module -J527-. From the Steering Column Electronics Control Module -J527-, the information is transferred to the individual components via the CAN bus (comfort) and the Data Bus On Board Diagnostic Interface -J533-.

Fault Finding is performed using the "Guided Fault Finding" on Vehicle Diagnostic Tester.
