B0530 Buick Code - Left Turn Signal Circuit
Quick Answer
When the Body Control Module (BCM) receives a left turn signal ON command from the turn signal switch, the BCM will apply a voltage to the left turn signal indicator supply voltage circuit. Common causes include Faulty Instrument Panel Cluster (IPC), Instrument Panel Cluster (IPC) harness is open or shorted, Instrument Panel Cluster (IPC) 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.
