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.
DIAGNOSIS AND TESTING - MULTI-FUNCTION
SWITCH
To test turn signal, headlamp beam select and opti-
cal horn portion of the multi-function switch:
(1) Remove the multi-function switch, refer to
Electrical, Lamps/Lighting - Exterior, Multi-Function
Switch, Removal, and Installation.
(2) Using an ohmmeter check the resistance read-
ings between multi-function switch pins. Refer to
Wiring Diagrams for proper pin numbers and the
MULTI-FUNCTION SWITCH RESISTANCE table.

OVERHEAD CONSOLE
DESCRIPTION
Three overhead consoles are available on RS/RG
models. These are the Electronic Vehicle Information
Center (EVIC), Compass Mini-Trip Computer
(CMTC) or a Compass Temperature Computer (CT).
All consoles are equipped with two reading/courtesy
lamps and if the vehicle is equipped with a power
liftgate or power sliding door(s) the overhead console
will also include command switches for these fea-
tures. The overhead console is mounted with one
screw and two snap clips to a molded plastic retainer
bracket located above the headliner.
DESCRIPTION - COMPASS
All the available overhead consoles on this model
include Compass information. While in the compass/temperature mode, the compass will display the
direction in which the vehicle is pointed using the
eight major compass headings (Examples: north is N,
northeast is NE). The self-calibrating compass unit
requires no adjusting in normal use. The only cali-
bration that may prove necessary is to drive the vehi-
cle in three complete circles at 5 to 8 kilometers-per-
hour (3 to 5 miles-per-hour), on level ground, in not
less than forty-eight seconds. This will reorient the
compass unit to its vehicle.
The compass unit also will compensate for magne-
tism the body of the vehicle may acquire during nor-
mal use. However, avoid placing anything magnetic
directly on the roof of the vehicle. Magnetic mounts
for an antenna, a repair order hat, or a funeral pro-
cession flag can exceed the compensating ability of
the compass unit if placed on the roof panel. Mag-
netic bit drivers used on the fasteners that hold the
overhead console assembly to the roof header can
