The steering wheel control switches duplicate the function of the primary
controls of the associated component,
through a network of momentary contact switches and a series of resistors. The
body control module (BCM)
supplies voltage to the switches and monitors the return signal. When a switch
is pressed, a specific voltage
drops across the resistor unique to that switch. The BCM identifies the switch
selected and sends a serial data
message to the component controlled by the switch, activating the feature.
This section is intended to diagnose the circuits between the BCM and the
steering wheel control switches. If
the primary control for the device is inoperative, refer to the appropriate
section for the component the steering
wheel control switch is used for.
