U147E RAM Code - Implausible Data Received From Left 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 Left Blind Spot Sensor (LBSS), Left Blind Spot Sensor harness is open or shorted, Left 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 U147E 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) will set if incorrect data received from the Left Blind Spot Sensor (LBSS).
What are the Possible Causes of the DTC U147E RAM?
- Faulty Left Blind Spot Sensor (LBSS)
- Left Blind Spot Sensor harness is open or shorted
- Left Blind Spot Sensor circuit poor electrical connection
How to Fix the DTC U147E RAM?
