Code B2332 RAM Description

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 Diagnostic Trouble Code (DTC) sets when the Steering Control Module senses that the Horn Switch is in the Set position for greater than 50 seconds.
