B23A1 RAM Description
The Flash to Pass/Optical Horn Switch for this vehicle is integral to the Multifunction Switch. The Multifunction Switch is connected to the left side of the Clockspring/SAS. The Multifunction switch provides the primary controls for the front and rear wiper and washer systems, turn signals and for headlamp high beam selection. The Multifunction Switch communicates with the Steering Angle Sensor (SAS) (integral to the Steering Column Control Module) via the LIN Bus. The SAS then converts this data to a CAN Bus signal and broadcasts the message to the corresponding module on the bus.
