Turn Signals

Right and left turn signal indicators are hard wired to turn signal switch and hazard switch. Turn signal indicator illuminates when turn signal lights supply voltage circuit is active. Body Control Module (BCM) is also hard wired to turn signal switch. If BCM determines that turn signal flasher signal circuit is active for more than 1.2 km (0.75 mile), BCM sends a class 2 message to radio in order to activate an audible warning.
