Turn Signals: Description and Operation

Turn Signal Operation


With the ignition switch in RUN, voltage is supplied to the turn signal/hazard relay contact and flasher unit.

The flasher unit provides pulsed voltage to the turn signal switch. When the turn signal switch is pushed to LEFT, pulsed voltage is provided to the left front and rear turn signal lights, the left turn signal indicator light, and the front side marker flasher relay. The front side marker flasher relay in turn provides pulsed voltage to the left front side marker light. The front side marker flasher relay also receives an input from the headlight switch. When the headlight switch is in HEAD or PARK, the front side marker light will flash alternately with the other turn signal lights.


Hazard Lights Operation


With the hazard switch ON, voltage is applied at all times to the turn signal/hazard relay. Hazard light operation is similar to turn signal operation, except that all the lights flash simultaneously.
