Turn Signal Switch: Description and Operation
MULTI-FUNCTION SWITCH
Turn Signal System
The turn signals are actuated with a lever on Multi-Function Switch, located on the left side of the steering wheel. The signals are automatically
turned OFF by a canceling cam (two lobes molded to the clock spring mechanism). The cam comes in contact with the cancel actuator on the turn
signal (multi-function) switch assembly. Either cam lobe, pushing on the cancel actuator, returns the switch to the OFF position. The
multi-function switch is a resistive MUX switch that feeds inputs to the BCM.
Lane change signaling is actuated by applying partial turn signal stalk movement toward the direction desired until the indicator lamps flashes in
the instrument cluster. When the switch stalk is released the stalk will spring back into the neutral position turning OFF the turn signal.
With the ignition switch ON and the turn signal switch stalk actuated left or right, current flows through the:
-
Multi-function switch
-
Body Control Module
-
Integrated Power Module (IPM)
-
Turn indicator lamp
-
Front and rear turn signal bulbs.
A chime will sound after the vehicle has traveled a distance of approximately 1.0 mile and a speed of 15 mph, with the turn signal ON.
