The turn signal flasher, which is integrated within the BCM, will flash the left 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 left turn signal command and the left turn signal indicator supply voltage circuit is open, shorted to ground, or shorted to voltage.
