Theory Of Operation
The Steering Wheel Control Audio Switch, when pressed, sends a multiplexed signal to the Right Steering Switch. The switching status is transferred to the Steering Control Module (SCM) by way of the LIN bus, a serial sub-bus. The SCM converts the data to CAN(B) and sends the message to the corresponding module on the bus.
The Steering Wheel Control Menu Switch is part of the Right Steering Switch. The switching status is transferred to the Steering Control Module (SCM) by way of the LIN bus, a serial sub-bus. The SCM converts the data to CAN(B) and sends the message to the corresponding module on the bus.
The Steering Wheel Control Up Switch, when pressed, sends a multiplexed signal to the Right Steering Switch. The switching status is transferred to the Steering Column Control Module (SCCM) by way of the LIN bus, a serial sub-bus. The SCCM converts the data to CAN(B) and sends the message to the corresponding module on the bus.
The Steering Wheel Control Down Switch, when pressed, sends a multiplexed signal to the Right Steering Switch. The switching status is transferred to the Steering Control Module (SCM) by way of the LIN bus, a serial sub-bus. The SCM converts the data to CAN(B) and sends the message to the corresponding module on the bus.
The Steering Wheel Control Side Switch, when pressed, sends a multiplexed signal to the Right Steering Switch. The switching status is transferred to the Steering Control Module (SCM) by way of the LIN bus, a serial sub-bus. The SCM converts the data to CAN(B) and sends the message to the corresponding module on the bus.
The Steering Wheel Control Plus (+) Switch is part of the Right Steering Switch. The switching status is transferred to the Steering Control Module (SCM) by way of the LIN bus, a serial sub-bus. The SCM converts the data to CAN(B) and sends the message to the corresponding module on the bus.
The Steering Wheel Control Minus (-) Switch is part of the Right Steering Switch. The switching status is transferred to the Steering Control Module (SCM) by way of the LIN bus, a serial sub-bus. The SCM converts the data to CAN(B) and sends the message to the corresponding module on the bus.
The Steering Wheel Control Compass/Temperature Switch is part of the Right Steering Switch. The switching status is transferred to the Steering Control Module (SCM) by way of the LIN bus, a serial sub-bus. The SCM converts the data to CAN(B) and sends the message to the corresponding module on the bus.
The Horn Switch is connected to the Right Steering Switch. The switching status is transferred to the Steering Control Module (SCM) by way of the LIN bus, a serial sub-bus. The SCM converts the data to CAN B and sends the message to the corresponding module on the bus.
The Steering Wheel Control Switch status is transferred to the Steering Control Module (SCM) by way of the LIN bus, a serial sub-bus. The SCM converts the data to CAN and sends the messages to the corresponding module(s) on the bus.
