Turn Signal Cancel Cam: Description and Operation
The turn signal cancelling cam is concealed within the steering column below the steering wheel. The turn signal cancelling cam consists of two lobes
that are integral to the lower surface of the clockspring rotor. The clockspring mechanism provides turn signal cancellation as well as a constant
electrical connection between the horn switch, driver side airbag module and speed control switches on the steering wheel and the instrument panel wire
harness on the steering column. The housing of the clockspring is secured to the steering column and remains stationary. The rotor of the clockspring,
including the turn signal cancelling cam lobes rotate with the steering wheel.
The turn signal cancelling cam is integral to the clockspring and cannot be repaired. If faulty or damaged, the entire clockspring assembly must be
replaced.
The turn signal cancelling cam has two lobes molded into the lower surface of the clockspring rotor. When the turn signals are activated by moving the
multi-function switch control stalk to a detent position, a turn signal cancel actuator is extended from the inside surface of the multi-function switch
housing toward the clockspring rotor. When the steering wheel is rotated during the turn, one of the two turn signal cancelling cam lobes will contact the
turn signal cancel actuator, releasing the multi-function switch control stalk from its detent and cancelling the turn signal event.
