Turn Signals: Description and Operation

The turn signal system consists of:
^ turn signal miniature bulbs.
^ turn signal indicators in the instrument cluster.
^ lighting control module.
^ multi-function switch.
^ circuit wiring and circuit protection.

Power is supplied to the lighting control module through instrument panel Fuse 6 (10 A). This fuse is hot in START or RUN. The lighting control module is connected to the turn signal switch portion of the multi-function switch. Ground is provided to the lighting control module and the turn signal miniature bulbs through Circuit 57 (BK).

Turn signal functions are performed by double filament bulbs in lamp assemblies located next to the headlamps. The turn/hazard function uses the second filament of the appropriate bulb(s).
^ With the multi-function switch in the right turn position, power is supplied to the RH front and rear turn signal miniature bulbs and the right turn indicator in the instrument cluster.
^ With the multi-function switch in the left turn position, power is supplied to the LH front and rear turn signal miniature bulbs and the left turn indicator in the instrument cluster.
