Turn Signal Cancel Cam: Description and Operation
Description
DESCRIPTION
The turn signal cancel cam (3) is concealed within the steering column. The turn signal cancel cam consists of two lobes on a molded plastic ring that is
snapped into the lower hub of the clockspring rotor. The clockspring mechanism provides turn signal cancellation as well as a constant electrical
connection between the horn switch, driver airbag, speed control switches, and remote radio switches on the steering wheel and the instrument panel wire
harness on the steering column. The housing of the clockspring (2) is secured to the multi-function switch mounting housing on the steering column and
remains stationary. The rotor of the clockspring, including the turn signal cancel cam lobes rotate with the steering wheel.
The turn signal cancel cam is serviced as a unit with the clockspring and cannot be repaired. If ineffective or damaged, the entire clockspring unit must
be replaced. See: Restraint Systems/Air Bag Systems/Clockspring Assembly / Spiral Cable/Service and Repair/Removal and Replacement/Removal .
