Audi Q5: Multifunction Steering Wheel, General Information
Buttons are integrated in the steering wheel for easier operation of Infotainment, telephone and the navigation system. On vehicles with Tiptronic, rocker switches are also installed on the left and right.
The Multifunction Steering Wheel Control Module -J453- (under 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-.
Perform the Fault Finding with the Vehicle Diagnostic Tester.
