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 rear stop/turn lamp supply voltage circuit and right turn signal lamps supply voltage circuit. The turn signal flasher is integrated within the BCM and will flash both circuits simultaneously. The turn signal indicator is also illuminated utilizing the right rear stop/turn lamp supply voltage circuit. The Diagnostic Trouble Code (DTC) is set when the right front and/or right rear turn signals will not operate or will remain always ON.
