Steering Wheel Controls Description and Operation
The audio steering wheel control switches duplicate the function of the primary controls of the associated component, through a network of multiple
momentary contact switches and a series of resistors. The radio supplies voltage to the switches and monitors the return signal for a specific voltage drop
to occur unique to the one pressed. The radio then identifies the switch selected to activate the feature, otherwise sends a serial data message that is
received by the component controlled, activating the feature.
This information is intended to diagnosis the circuits between the radio and the audio steering wheel control switches. If the primary control for the
device is inoperative, refer to the appropriate information for the component the steering wheel control switch is functioning.
