Hazard Warning Flasher: Description and Operation
The turn signal flasher and the hazard warning flasher are combined into one unit called a Combination Flasher (combo-flasher). The combo-flasher is a
smart relay located on the back of the multi-function switch. The combo-flasher is black in color and has a dampener material wrapped on it. Constant
battery voltage is supplied to the flasher so that it can perform the hazard warning function, and ignition switched battery voltage is supplied for the turn
signal function. However, when the flasher is idle no current is drawn through the module. The unit does not become active until it is provided a signal
ground from the turn signal switch or hazard warning switch.
The combo-flasher controls the flashing of the hazard warning system and the turn signal system. An inoperative bulb or incomplete turn signal circuit
will cause the flasher rate to double. Typical flash rate is about ninety flashes per minute. When a bulb is burnt out, or when a circuit for a lamp is open,
the turn signal flash rate will increase to a minimum of 180 flashes per minute. However, an open lamp circuit or burnt out bulb does not change the
hazard warning flash rate.
Turn signal inputs that actuate the combination flasher are low current grounds, each drawing a maximum of 300 milliamperes. The turn signal inputs
are provided to the flasher through the multifunction switch on the steering column. The hazard warning signal input is a low current ground drawing a
maximum of 600 milliamperes. The hazard warning input can be provided through the multifunction switch on the steering column.
