(3) Gently push the plunger on the brake lamp
switch in until it stops.
(4) With the switch in this depressed position
(plunger pushed in), use an ohmmeter to test each of
the three internal switches as shown (Fig. 2). You
should achieve the results as listed in the figure.
If you do not achieve the results as listed in both
figures, the switch is faulty and must be replaced.
Refer to Removal And Installation in this section.
If the switch is found to be operating properly, it
may be misadjusted. Do not reinstall the switch,
replace it. (Refer to 8 - ELECTRICAL/LAMPS/
LIGHTING - EXTERIOR/BRAKE LAMP SWITCH -
INSTALLATION)
CAUTION: The switch can only be adjusted once.
That is during initial installation of the switch. If the
switch is not adjusted properly or has beenremoved for any reason, a new switch must be
installed and adjusted.
REMOVAL
(1) Disconnect and isolate the battery negative
cable from its post on the battery.
(2) Remove silencer panel below steering column
and knee blocker.
(3) Remove the brake lamp switch by rotating the
switch in a counterclockwise direction approximately
30 degrees and pulling it out of the bracket (Fig. 3).
(4) Release the locking tab and disconnect the wir-
ing connector from the switch.
(5) Discard the brake lamp switch. It must not be
reused.
INSTALLATION
CAUTION: Do not reuse the original brake lamp
switch. The switch can only be adjusted once. That
is during initial installation of the switch. If the
switch is not adjusted properly or has been
removed for some service, a new switch must be
installed and adjusted.
(1) Mount and adjust the NEW brake lamp switch
using the following procedure:
(a) Connect the wiring connector to the switch
and latch the locking tab.

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.
