When the Body Control Module (BCM) receives a left turn signal ON command from the turn signal switch, the BCM will apply voltage to the left rear stop/turn lamp supply voltage circuit and left 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 left rear stop/turn lamp supply voltage circuit. The Diagnostic Trouble Code (DTC) is set when the left front and/or left rear turn signals will not operate or will remain always ON.
