MULTI-FUNCTION SWITCH
DESCRIPTION - 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-func-
tion) 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.

OPERATION - TURN SIGNAL SYSTEM
Lane change signaling is actuated by applying par-
tial 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:
²Multi-function switch
²Body Control Module
²Integrated Power Module (IPM)
²Turn indicator lamp
²Front 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.
