U11FA RAM Code - Lost Communication With Right Blind Spot Sensor
Quick Answer
The Blind Spot Monitor (BSM) system has two primary components; a Left Blind Spot Sensor (LBSS) and Right Blind Spot Sensor (RBSS). Common causes include Faulty Right Blind Spot Sensor, Right Blind Spot Sensor harness is open or shorted, Right Blind Spot Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U11FA RAM 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.
What are the Possible Causes of the DTC U11FA RAM?
- Faulty Right Blind Spot Sensor
- Right Blind Spot Sensor harness is open or shorted
- Right Blind Spot Sensor circuit poor electrical connection
How to Fix the DTC U11FA RAM?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
