Turn Signals: Description and Operation

The turn signal system consists of:
- Turn signal miniature bulbs
- Lighting control module
- Multifunction switch
- Indicator bulbs in the virtual image instrument cluster
- Circuit wiring and circuit protection

Turn signal system operates as follows:
- The multi-function switch is protected by fuse junction panel Fuse 3 (10A). This fuse is hot in RUN.
- Circuits 104 (LB/O) and 105 (R/W) connect lighting control module to the left and right turn signal switches 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 utilizes 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 RH 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 LH turn indicator in the instrument cluster.
