Turn Signals: Description and Operation

PRINCIPLES OF OPERATION

Turn Signal/Hazard Lamps
Switched ignition voltage is supplied to the electronic flasher relay for the turn signals. Power is then routed to the multifunction switch. When the multifunction switch is placed in the LH or RH turn positions, voltage is routed to the LH or RH turn signal lamps. The electronic flasher relay will then cycle the voltage on and off approximately 80 times per minute. If a front or rear turn bulb is inoperative, the electronic flasher relay will then cycle the voltage on and off approximately 160 times per minute. The hazard switch is integral to the multifunction switch. Battery voltage is supplied to the electronic flasher for the hazard lamp operation. The electronic flasher routes power to the multifunction switch. When the hazard switch is engaged, power is routed to all the turn lamps. The electronic flasher relay will then cycle the voltage on and off approximately 80 times per minute.
