2002 JEEP LIBERTY low beam

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.

HEADLAMP ALIGNMENT SCREEN PREPARATION
Prepare an alignment screen as illustrated.
(1) Position the vehicle on a level surface perpen-
dicular to a flat wall 7.62 meters (25 feet) away from
the front of the headlamp lens for North American
vehicles, or 10.0 meters (32.81 feet) away from the
front of the headlamp lens for Rest-Of-World vehicles
(Fig. 43). If necessary, tape a line on the floor at the
appropriate distance away from and parallel to the
wall.
(2) Measure up on the wall 1.27 meters (5 feet)
from the floor and tape a vertical line on the align-
ment screen at the centerline of the vehicle. Sight
along the centerline of the vehicle (from the rear of
the vehicle forward) to verify the accuracy of the cen-
terline placement.
(3) Rock the vehicle from side-to-side three times
to allow the suspension to stabilize, then jounce the
front suspension three times by pushing downward
on the front bumper and releasing. Measure the dis-
tance from the center of the headlamp lens to the
floor. Transfer this measurement to the alignment
screen and tape a horizontal line on the wall at this
mark. This line will be used for up-and-down adjust-
ment reference.(4) Measure the distance from the centerline of the
vehicle to the center of each headlamp being aligned.
Transfer these measurements to the alignment
screen and tape a vertical line this distance to each
side of the vehicle centerline. These lines will be used
for left/right reference.
HEADLAMP ADJUSTMENT
A properly aligned headlamp will project a pattern
on the alignment screen from just below horizontal to
75 millimeters (3 inches) below the headlamp center-
line for vehicles in North America, or from just below
horizontal to 125 millimeters (5 inches) below the
headlamp horizontal centerline for vehicles in Rest-
Of-World.
(1) Vehicles for all markets except Japan should
have the headlamp low beams selected with the dim-
mer (multi-function) switch during the adjustment
procedure. Vehicles for the Japanese market should
have the headlamp high beams selected.
(2) Cover the lens of the headlamp that is not
being adjusted.
(3) Turn the adjusting screw (Fig. 44) until the top
edge of the beam intensity pattern is positioned from
just below horizontal to 75 millimeters (3 inches)

OPERATION
The multi-function switch uses a combination of
resistor multiplexed and conventionally switched out-
puts to control the many functions and features it
provides. The switch receives battery current on a
fused ignition switch output (run-acc) circuit from a
fuse in the Junction Block (JB) whenever the ignition
switch is in the On or Accessory positions. The switch
receives a path to ground at all times through a
splice block located in the instrument panel wire har-
ness with an eyelet terminal connector that is
secured by a nut to a ground stud on the driver side
instrument panel end bracket near the Junction
Block (JB). Following are descriptions of how each of
the two multi-function switch control stalks operate
to control the functions and features they provide.
LEFT CONTROL STALK The left (lighting) control
stalk of the multi-function switch operates as follows:
²Front Fog Lamps- For vehicles so equipped,
the control knob on the end of the multi-function
switch left (lighting) control stalk is pulled outward
to activate the optional front fog lamps. The control
knob is mechanically keyed so that it cannot be
pulled outward unless it is first rotated to turn on
the exterior lighting. The multi-function switch pro-
vides a resistor multiplexed output to the Body Con-
trol Module (BCM) on a fog lamp switch sense
circuit, and the BCM responds by energizing or de-
energizing the front fog lamp relay in the Junction
Block (JB) as required.
²Headlamps-
The control knob on the end of the
multi-function switch left (lighting) control stalk is
rotated forward (counterclockwise) to its second detent
position to activate the headlamps. The multi-function
switch provides a resistor multiplexed output to the
Body Control Module (BCM) on a headlamp switch
sense circuit, and the BCM responds by energizing or
de-energizing the selected low or high beam relay
(Daytime Running Lamp relay in Canadian vehicles)
in the Junction Block (JB) as required.
²Headlamp Beam Selection-The left (lighting)
control stalk of the multi-function switch is pulled
towards the steering wheel past a detent to actuate
the integral beam select switch circuitry. Each time the
control stalk is activated in this manner, the opposite
headlamp beam from what is currently selected will be
energized. The multi-function switch provides a ground
output to the Body Control Module (BCM) on a high
beam switch sense circuit, and the BCM responds by
energizing or de-energizing the selected low or high
beam relay (Daytime Running Lamp relay in Canadian
vehicles) in the Junction Block (JB) as required.
