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 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.
