²Coil Battery Terminal- The coil battery ter-
minal (86) is connected to a control output of the
Body Control Module (BCM) through a low beam
relay control circuit. The BCM controls headlamp low
beam operation by controlling a ground path through
this circuit.
²Normally Open Terminal- The normally open
terminal (87) is connected to the headlamp low beam
filaments through the low beam relay output circuit
and provides battery current to the headlamp low
beams whenever the relay is energized.
²Normally Closed Terminal- The normally
closed terminal (87A) is not connected in this appli-
cation.
The headlamp low beam relay can be diagnosed
using conventional diagnostic tools and methods.
DIAGNOSIS AND TESTING - HEADLAMP LOW
BEAM RELAY
The headlamp low beam relay (Fig. 38) is located
in the Junction Block (JB) under the driver side out-
board end of the instrument panel. Refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.

MULTI-FUNCTION SWITCH
DESCRIPTION
The multi-function switch is located on the steering
column, just below the steering wheel (Fig. 50). The
only visible components of the multi-function switch
are two levers, or control stalks that extend through
dedicated openings in each side of the steering col-
umn shrouds. The remainder of the switch, its
mounting provisions, and its electrical connections
are all concealed beneath the steering column
shrouds. The switch housing and controls are con-
structed of molded black plastic. A saddle-like forma-
tion in the center of the multi-function switch
housing straddles the steering column tube just
below the column lock housing, and two posts inte-
gral to the lower surface of the switch housing
engage two holes on the forward-facing side of the
lock housing. Two integral ledge-like locating tabs
near the top of the rearward facing switch housing
surface are supported and located by two upright
stanchions that extend upward from the top of the
lock housing. Also on the rearward facing switch
housing surface near the center, an integral ledge-
like mounting tab rests on a similar ledge-like tab
that extends from each side of the steering column
lock housing. When the steering column shrouds are
installed on the column, the switch mounting tabs
are clamped along with the mounting tabs of the
clockspring between the integral mounting stan-
chions of the upper shroud and the lock housing tabs,
and are secured to the steering column lock housing
by the same two screws that secure the two shroud
halves to each other and the column.
There are several versions of the multi-function
switch to support both optional equipment and equip-
ment that is required only in certain markets. Each
multi-function switch control stalk has both white
nomenclature and International Control and Display
Symbol graphics applied to it, which clearly identify
its many functions. Each control stalk has a control

OPERATION
The rear fog lamp relay is an electromechanical
switch that uses a low current input from the Body
Control Module (BCM) to control a high current out-
put to the rear fog lamps. The movable common feed
contact point is held against the fixed normally
closed contact point by spring pressure. When the
relay coil is energized, an electromagnetic field is
produced by the coil windings. This electromagnetic
field draws the movable relay contact point away
from the fixed normally closed contact point, and
holds it against the fixed normally open contact
point. When the relay coil is de-energized, spring
pressure returns the movable contact point back
against the fixed normally closed contact point. A
resistor is connected in parallel with the relay coil in
the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as
the electromagnetic field of the relay coil collapses.
The rear fog lamp relay terminals are connected to
the vehicle electrical system through a connector
receptacle in the Junction Block (JB). The inputs and
outputs of the rear fog lamp relay include:
²Common Feed Terminal- The common feed
terminal (30) receives battery current at all times
from a fuse in the JB through a fused B(+) circuit.
²Coil Ground Terminal- The coil ground termi-
nal (85) is connected to a control output of the pre-
mium Body Control Module (BCM) through a rear
fog lamp relay control circuit. The BCM controls rear
fog lamp operation by controlling a ground path
through this circuit.
²Coil Battery Terminal- The coil battery ter-
minal (86) receives battery current at all times from
a fuse in the JB through a fused B(+) circuit.
²Normally Open Terminal- The normally open
terminal (87) is connected to the rear fog lamps
through a rear fog lamp relay output circuit and pro-
vides battery current to the rear fog lamps whenever
the relay is energized.
²Normally Closed Terminal- The normally
closed terminal (87A) is not connected in this appli-
cation.
The rear fog lamp relay can be diagnosed using
conventional diagnostic tools and methods.
