The Smart Wheel Steering Wheel System
offers control of the horn, headlamp, marker
lamp flash, cruise control and wiper functions
from switch panels mounted on the steering
wheel. The system consists of electronic
modules enclosed in the steering wheel
and the Master Controller typically
generate unique signals as each
switch closes and will then transmit
them to the Master Controller. The
Master Controller decodes the signal for the
closed switch and operates the corresponding
080308
outputs for that function. Two additional
wires provide power and ground for the
steering wheel backlighting.
