B2339 RAM Description
The Horn Switch is connected to the Right Steering Switch. The switching status is transferred to the Cluster by way of the LIN bus, a serial sub-bus. The Cluster converts the data to a CAN Bus signal and sends the message to the corresponding module on the bus. The Diagnostic Trouble Code (DTC) sets when the Cluster senses that the Horn Switch is pressed for greater than 45 seconds.
