Turn Signal Lamp: Description and Operation

2006 Saturn ION L4-2.0L SC VIN PSECTION Description and Operation


TURN SIGNAL LAMPS

When the turn signal switch is place in either the right or left turn position, the turn/hazard request circuit is pulled low, through a resistor. The body control module (BCM) uses the resistors to determine if the left or right turn signals have been requested. The BCM then supplies an ON-OFF voltage to the turn signal lamps and turn signal indicator on the selected side of the vehicle. The turn signals receive a ground at G101, G401, or G403.
