B0525 GMC – Right Turn Signal Circuit

B0525 GMC Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

B0525 GMC Possible Causes

Faulty Instrument Panel Cluster (IPC),Instrument Panel Cluster (IPC) harness is open or shorted,Instrument Panel Cluster (IPC) circuit poor electrical connection,Faulty Body Control Module (BCM)

B0525 GMC Description

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 turn signal indicator supply voltage circuit. The turn signal flasher, which is integrated within the BCM, will flash the right turn signal indicator lamp in the Instrument Panel Cluster (IPC) simultaneously with the turn signal lamps. The BCM will set the Diagnostic Trouble Code (DTC) when the BCM receives a right turn signal command and the right turn signal indicator supply voltage circuit is open, shorted to ground, or shorted to voltage.
