Code U11FA Dodge Description
The microprocessor analyzes the sensor data to determine whether any detected objects should be reported. When it is determined that an object should be reported, the Sensor controls its respective left or right BSM display directly through a hard wired output to the Outside Rearview Mirrors. The sensor also sends an electronic request message over the CAN Bus to the radio. The Radio then mutes any current output through the speakers and generates a chime as an audible alert.
Each sensor performs a bulb test by illuminating the triangle icon in the Outside Rearview Mirror at each ignition ON cycle.
The Diagnostic Trouble Code (DTC) sets when no BUS messages from the Right Blind Spot Sensor (RBSS) are received for greater than 1.05 seconds.
