B0532 Code - Left Turn Signal Circuit Low
Quick Answer
When the Body Control Module (BCM) receives a left turn signal ON command from the turn signal switch, the BCM will apply voltage to the left rear stop/turn lamp supply voltage circuit and left turn signal lamps supply voltage circuit. Common causes include Faulty Left Turn Signal Lamp Bulb, Left Turn Signal Lamp Bulb harness is open or shorted, Left 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.
