### Inflatable Restraint Steering Wheel Module Coil

The inflatable restraint steering wheel module coil assembly contains 4 wires used by the steering wheel controls. The 4 wires allow the voltage to be applied while the steering wheel is being turned.

### Steering Wheel Radio Control Switches

The radio control switch controls the volume and the station frequency. The radio control switch receives power from the RSA/SWC Reference power circuit from the radio via CKT 314. Press the switch to the desired function in order to allow a different voltage output through CKT 1796 to the radio for each switch pressed. This change in voltage is provided by a network of series resistors inside the steering wheel control switches.
