B0528 Code - Right Turn Signal Circuit High
Quick Answer
When the Body Control Module (BCM) receives a right turn signal ON command from the turn signal switch, the BCM will apply voltage to the right rear stop/turn lamp supply voltage circuit and right turn signal lamps supply voltage circuit. Common causes include Faulty Right Turn Signal Lamp Bulb, Right Turn Signal Lamp Bulb harness is open or shorted, Right Turn Signal Lamp Bulb circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
