Hazard Warning Lamps: Description and Operation

Hazard Warning Lamps

The hazard warning lamps use the front and rear turn signal indicator lamps as previously described. These are controlled by the LCM in response to a hazard warning lamp request from the instrument panel switch.

Crash Signal Activation
In the event of an accident of a severity to activate and deploy the airbags, the restraint control module requests various electrical operations to assist with the crash situation. The restraints control module requests via the bus systems to the LCM to activate the hazard warning lamps. These will continue to operate until deselected using the hazard warning lamp switch in the instrument panel. The lamps flash at a frequency which is the same as the frequency used to flash the headlamp high beam in the same situation.
