Code B284A RAM Description

The B284A diagnostic trouble code (DTC) indicates a low voltage condition in the Passenger Blind Spot Warning Light Control Circuit. This code is typically associated with vehicles equipped with advanced driver-assistance systems (ADAS), particularly those featuring blind spot monitoring (BSM) systems. The BSM system utilizes sensors located in the rear corners of the vehicle to detect vehicles in adjacent lanes, alerting the driver through visual indicators, usually located in the side mirrors or on the dashboard.
