HEADLAMP LOW BEAM RELAY
DESCRIPTION
The headlamp low beam relay is located in the
Junction Block (JB) below the driver side outboard
end of the instrument panel in the passenger com-
partment of the vehicle. The headlamp low beam
relay is a conventional International Standards
Organization (ISO) micro relay (Fig. 37). Relays con-
forming to the ISO specifications have common phys-
ical dimensions, current capacities, terminal
patterns, and terminal functions. The relay is con-
tained within a small, rectangular, molded plastic
housing and is connected to all of the required inputs
and outputs by five integral male spade-type termi-
nals that extend from the bottom of the relay base.
The headlamp low beam relay cannot be adjusted
or repaired and, if faulty or damaged, the unit must
be replaced.
OPERATION
The headlamp low beam relay is an electromechan-
ical switch that uses a low current input from the
Body Control Module (BCM) to control a high current
output to the headlamp low beam filaments. 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 electro-
magnetic field is produced by the coil windings. This
electromagnetic field draws the movable relay con-
tact point away from the fixed normally closed con-
tact point, and holds it against the fixed normally
open contact point. When the relay coil is de-ener-
gized, 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 headlamp low beam relay terminals are con-
nected to the vehicle electrical system through a con-
nector receptacle in the Junction Block (JB). The
inputs and outputs of the headlamp low beam relay
include:
²Common Feed Terminal- The common feed
terminal (30) receives battery current at all times
from a fuse in the Power Distribution Center (PDC)
through a fused B(+) circuit.
²Coil Ground Terminal- The coil ground termi-
nal (85) receives battery current at all times from a
fuse in the PDC through a fused B(+) circuit.

(3) Position the multi-function switch onto the
steering column lock housing. Be certain that the
switch alignment posts and locator tabs are fully
seated on the lock housing.
(4) Position the upper and lower shrouds onto the
steering column.
(5) Align the snap features on the lower shroud
with the receptacles on the upper shroud and apply
hand pressure to snap them together.
(6) From below the steering column, install and
tighten the two screws that secure the lower shroud
to the upper shroud. Tighten the screws to 2 N´m (20
in. lbs.).
(7) If the vehicle is equipped with the optional tilt
steering column, move the tilt steering column back
to the fully raised position and move the tilt release
lever into the locked (up) position.
(8) Reconnect the battery negative cable.
PARK LAMP RELAY
DESCRIPTION
The park lamp relay is located in the Junction
Block (JB) below the driver side outboard end of the
instrument panel in the passenger compartment of
the vehicle. The park lamp relay is a conventional
International Standards Organization (ISO) micro
relay (Fig. 53). Relays conforming to the ISO specifi-
cations have common physical dimensions, current
capacities, terminal patterns, and terminal functions.
The relay is contained within a small, rectangular,
molded plastic housing and is connected to all of therequired inputs and outputs by five integral male
spade-type terminals that extend from the bottom of
the relay base.
The park lamp relay cannot be adjusted or
repaired and, if faulty or damaged, the unit must be
replaced.
OPERATION
The park 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 park 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 park 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 park lamp relay include:
²Common Feed Terminal- The common feed
terminal (30) is connected to the park lamps through
the park lamp relay output circuit and provides
ground to the park lamps when the relay is de-ener-
gized, and battery current to the park lamps when-
ever the relay is energized.
²Coil Ground Terminal-
The coil ground termi-
nal (85) is connected to a control output of the Body
Control Module (BCM) through a park lamp relay con-
trol circuit. The BCM controls park 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 PDC through a fused B(+) circuit.
²Normally Open Terminal- The normally open
terminal (87) receives battery current at all times
from a fuse in the Power Distribution Center (PDC)
through a fused B(+) circuit.
²Normally Closed Terminal- The normally
closed terminal (87A) is connected to ground at all
times through a ground circuit that receives ground
through a splice block located in the instrument
panel wire harness 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).

POWER LOCKS
DESCRIPTION
POWER LOCKS
A power operated door and tailgate lock system is
available factory-installed equipment on this model.
The power lock system allows all of the doors and thetailgate to be locked or unlocked electrically by oper-
ating a switch on either front door trim panel. The
power lock system receives non-switched battery cur-
rent through a fuse in the Junction Block (JB), so
that the power locks remain operational, regardless
of the ignition switch position.
The Body Control Module (BCM) locks the doors
and tailgate automatically when the vehicle is driven
beyond the speed of 25.7 Km/h (15 mph), all doors
KJPOWER SYSTEMS 8N - 1

(4) Using an ohmmeter, check for continuity
between the pins of the wire harness connector while
pulling on the tailgate handle.
(5) If no continuity is found, replace the tailgate
handle assembly (Refer to 23 - BODY/DECKLID/
HATCH/LIFTGATE/TAILGATE/EXTERIOR HAN-
DLE - REMOVAL).
DOOR LOCK RELAY
DESCRIPTION
The power door lock system uses the following
relays for the front and rear passenger doors only:
²Driver door unlock relay
²Door lock relay
²Passenger Doors unlock relay
The tailgate uses outputs from the Body Control
Module (BCM).
The relays are electromechanical devices that
switch battery current to the door lock circuit when
the Body Control Module (BCM) grounds the relay
coil. These relays are located in the Junction Block
(JB). For complete circuit diagrams, 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.
The relays are a International Standards Organi-
zation (ISO) micro-relay. Relays conforming to the
ISO specifications have common physical dimensions,
current capacities, terminal patterns, and terminal
functions. The ISO micro-relay terminal functions
are the same as a conventional ISO relay. However,
the ISO micro-relay terminal pattern (or footprint) is
different, the current capacity is lower, and the phys-
ical dimensions are smaller than those of the conven-
tional ISO relay.
The relay cannot be repaired or adjusted and, if
faulty or damaged, it must be replaced.
OPERATION
The ISO relay consists of an electromagnetic coil, a
resistor and three (two fixed and one movable) elec-
trical contacts. The movable (common feed) relay con-
tact is held against one of the fixed contacts
(normally closed) by spring pressure. When the elec-
tromagnetic coil is energized, it draws the movable
contact away from the normally closed fixed contact,
and holds it against the other (normally open) fixed
contact.When the electromagnetic coil is de-energized,
spring pressure returns the movable contact to the
normally closed position. The resistor is connected in
parallel with the electromagnetic coil in the relay,
and helps to dissipate voltage spikes that are pro-
duced when the coil is de-energized.
DIAGNOSIS AND TESTING - DOOR LOCK
RELAY
The power lock relays (Fig. 4) are located in the
Junction Block (JB) under the instrument panel. For
complete circuit diagrams, refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, details of wire harness routing and
retention, connector pin-out information and location
views for the various wire harness connectors, splices
and grounds.

MODULE
DESCRIPTION
When an RKE lock message is sent to the Body
Control Module (BCM), the BCM actuates the doors
and the tailgate lock, the interior lighting is turned
off, the horn chirps (if this feature is enabled), the
exterior lamps flash (if this feature is enabled) and, if
the vehicle is so equipped, the Vehicle Theft Security
System (VTSS) is armed. When an RKE unlock mes-
sage is sent to the BCM, the BCM actuates the
driver side front door (or all doors and the tailgate if
this feature is enabled) unlock, the interior lighting
is turned on and, if the vehicle is so equipped, the
VTSS is disarmed.When an RKE panic message is sent to the BCM,
the BCM actuates the driver side front door (or all
doors and the tailgate if this feature is enabled)
unlock, the interior lighting is turned on and, if the
vehicle is so equipped, the VTSS is disarmed. The
panic message will also cause the exterior lamps
(including the headlights) to flash, and the horn to
pulse for about three minutes, or until a second panic
message is sent to the BCM. A vehicle speed of about
25.7 kilometers-per-hour (15 miles-per-hour) will also
cancel the panic event.
Refer to the owner's manual for more information
on the features, use and operation of the RKE sys-
tem.

POWER SEATS
DESCRIPTION
Individually controlled, electrically powered front
seats are available as factory-installed equipment on
this model. Vehicles with this option can be visually
identified by the two separate power seat switches,
mounted on each of the front seat cushion side
shields (Fig. 1). The power seat system option allows
the front seating positions to be electrically adjustedfor optimum vehicle control and comfort. The power
seat cushion can be adjusted forward, rearward, front
up, front down, rear up, or rear down. The power
seat system for this vehicle includes the following
major components, which are described in further
detail later in this section:
²Power Seat Switches- Two power seat
switches are used per vehicle, one for the driver and
one for the front seat passenger. Refer to the left and
right power seat switch information later in this sec-
tion.
²Power Seat Tracks- Two power seat tracks
are used per vehicle, one for the driver and one for
the front seat passenger seats. Refer to the power
seat track information later in this section.
²Circuit Breaker- An automatic resetting cir-
cuit breaker (# 1) is located in the Junction Block
and is used to protect the power seat system from
current overload.
Hard wired circuitry connects the power seat sys-
tem components to each other through the electrical
system of the vehicle. These hard wired circuits are
integral to several wire harnesses, which are routed
throughout the vehicle and retained by many differ-
ent methods. These circuits may be connected to each
other, to the vehicle electrical system and to the
power seat system components through the use of a
combination of soldered splices, splice block connec-
tors and many different types of wire harness termi-
nal connectors and insulators. Refer to theWiring
section of this manual for more information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, further details
on wire harness routing and retention, as well as
pin-out and location views for the various wire har-
ness connectors, splices and grounds.
Fig. 1 KJ Heated/Power Seat
8N - 14 POWER SEATSKJ

OPERATION
The power seat system receives battery current
through a fuse in the Power Distribution Center
(PDC) and a circuit breaker in the Junction Block,
regardless of the ignition switch position.
When a power seat switch control knob or knobs
are actuated, a battery feed and a ground path are
applied through the switch contacts to the appropri-
ate power seat track adjuster motor. The selected
adjuster motor operates to move the seat track
through its drive unit in the selected direction until
the switch is released, or until the travel limit of the
seat track is reached. When the switch is moved in
the opposite direction, the battery feed and ground
path to the motor are reversed through the switch
contacts. This causes the adjuster motor to run in the
opposite direction.
Refer to the owner's manual in the vehicle glove
box for more information on the features, use and
operation of the power seat system.
DIAGNOSIS AND TESTING - POWER SEATS
Before any testing of the power seat system is
attempted, the battery should be fully-charged and
all wire harness connections and pins cleaned and
tightened to ensure proper continuity and grounds.
Refer to the appropriate wiring information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, further details
on wire harness routing and retention, as well as
pin-out and joint connector location views for the var-
ious wire harness connectors, splices and grounds.
(1) If all power seats are inoperative, check the
automatic resetting circuit breaker in the Junction
Block. (Refer to 8 - ELECTRICAL/POWER DISTRI-
BUTION/CIRCUIT BREAKER - DIAGNOSIS AND
TESTING).
(2) With the dome lamp on, apply the power seat
switch in the direction of the failure.
(3) If the dome lamp dims, the seat or the power
seat track may be jammed. Check under and behind
the seat for binding or obstructions.
(4) If the dome lamp does not dim, proceed with
testing of the individual power seat system compo-
nents and circuits.
SEAT TRACK
DESCRIPTION
The six-way power seat option includes a power
seat track assembly located under each front seat
(Fig. 2). The power seat track assembly replaces the
standard manually operated seat tracks. The lower
half of the power seat track is secured at the frontwith two bolts to the floor panel seat cross member,
and at the rear with one bolt and one nut to the floor
panel. Four bolts secure the bottom of the seat cush-
ion frame to the upper half of the power seat track
unit.
The power seat track assembly cannot be repaired,
and is serviced only as a complete assembly. If any
component in this assembly is faulty or damaged, the
entire power seat track must be replaced.
OPERATION
The power seat track unit includes three reversible
electric motors that are secured to the upper half of
the track unit. Each motor moves the seat adjuster
through a combination of worm-drive gearboxes and
screw-type drive units. Each of the three driver side
power seat track motors also has a position potenti-
ometer integral to the motor assembly, which elec-
tronically monitors the motor position.
The front and rear of the seat are operated by two
separate vertical adjustment motors. These motors
can be operated independently of each other, tilting
the entire seat assembly forward or rearward; or,
they can be operated in unison by selecting the
proper power seat switch functions, which will raise
or lower the entire seat assembly. The third motor is
the horizontal adjustment motor, which moves the
seat track in the forward and rearward directions.
