Left Turn Signal
Range: ON/OFFThe BCM uses the left turn signal input in order to determine the state of the left turn signal.
ON displays when the left turn signal switch engages. This commands the left turn signal lamps to illuminate.
OFF displays when the left turn signal switch does not engage or the turn signal lamps do not illuminate.
The BCM monitors the vehicle speed input for activation of the turn signal reminder chime feature. The scan tool display alternates between ON and OFF as the turn signal flashes.
