removal JEEP LIBERTY 2002 KJ / 1.G Workshop Manual

Relays conforming to the ISO specifications have
common physical dimensions, current capacities, ter-
minal patterns, and terminal functions. The relay is
contained 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 trailer tow relays cannot be adjusted or
repaired and, if faulty or damaged, the inoperative
relay must be replaced.
OPERATION
The trailer tow relays are electromechanical
switches. The relays each use an input from the cir-
cuit that they isolate from the trailer wiring to con-
trol a high current output to the trailer. 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 electro-
magnetic 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 terminals of each trailer tow relay are con-
nected to the vehicle electrical system through a con-nector bank in the rear lighting wire harness above
the right rear wheelhouse. 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. The trailer tow relays can be diagnosed
using conventional diagnostic tools and methods.
DIAGNOSIS AND TESTING - TRAILER TOW
RELAY
The trailer tow relays (Fig. 65) are located in a
connector bank above the right rear wheelhouse.
Refer to the appropriate wiring information. The wir-
ing 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.

BAGS, DISABLE THE SUPPLEMENTAL RESTRAINT

OR INSTRUMENT PANEL COMPONENT DIAGNOSIS
OR SERVICE. DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE (GROUND) CABLE, THEN
WAIT TWO MINUTES FOR THE SYSTEM CAPACI-
TOR TO DISCHARGE BEFORE PERFORMING FUR-
THER DIAGNOSIS OR SERVICE. THIS IS THE ONLY
SURE WAY TO DISABLE THE SUPPLEMENTAL
RESTRAINT SYSTEM. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCI-
DENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
(1) Remove the trailer tow relay from the connec-
tor bank. (Refer to 8 - ELECTRICAL/LAMPS/LIGHT-
ING - EXTERIOR/TRAILER TOW RELAY -
REMOVAL).
(2) A relay in the de-energized position should
have continuity between terminals 87A and 30, and
no continuity between terminals 87 and 30. If OK, go
to Step 3. If not OK, replace the faulty relay.
(3) Resistance between terminals 85 and 86 (elec-
tromagnet) should be 75   8 ohms. If OK, go to Step
4. If not OK, replace the faulty relay.
(4) Connect a battery to terminals 85 and 86.
There should now be continuity between terminals
30 and 87, and no continuity between terminals 87A
and 30. If OK, test the input and output circuits of
the relay. Refer to the appropriate wiring informa-
tion.

DOOR AJAR SWITCH
DESCRIPTION
This vehicle has four door ajar switches, one for
each door. Each switch is concealed within and inte-
gral to its respective door latch unit. The switches
are momentary leaf contact-type units that are actu-
ated by the door latch mechanisms. A short pigtail
wire and connector on each door latch connects the
door ajar switch to the vehicle electrical system
through its respective door wire harness. The door
ajar switches cannot be adjusted or repaired and, if
faulty or damaged, the door latch unit must be
replaced. (Refer to 23 - BODY/DOOR - FRONT/
LATCH - REMOVAL) or (Refer to 23 - BODY/DOOR -
REAR/LATCH - REMOVAL).
OPERATION
The door ajar switches are actuated by the door
latch mechanisms. When a door is closed and prop-
erly latched, its door ajar switch is an open circuit.
When a door is open or only partially latched, the
door ajar switch is a closed circuit. The door ajar
switches are hard wired between a body ground and
the Body Control Module (BCM). The driver side
front door ajar switch is connected to the BCM
through a driver door ajar switch sense circuit, while
the remaining three door ajar switches are connected
to the BCM through a passenger door ajar switch
sense circuit in a parallel-series arrangement. The
BCM reads the door ajar switch status through an
internal pull-up, then uses these inputs to control
many electronic functions and features of the vehicle.
The door ajar switches can be diagnosed using con-
ventional diagnostic tools and methods; however, for
proper diagnosis of the BCM, and both the hard
wired and electronic BCM outputs affected by the
door ajar switch inputs, a DRBIIItscan tool is
required. Refer to the appropriate diagnostic infor-
mation.
FLIP-UP GLASS AJAR SWITCH
DESCRIPTION
A flip-up glass ajar switch is standard equipment
in this vehicle. This switch is concealed within and
integral to the flip-up glass latch unit. The switch is
a momentary leaf contact-type unit that is actuated
by the flip-up glass latch mechanism. A dedicated
connector receptacle on the flip-up glass latch unit
connects the flip-up glass ajar switch to the vehicle
electrical system through the tailgate wire harness.
The flip-up glass ajar switch cannot be adjusted or
repaired and, if faulty or damaged, the flip-up glass
latch unit must be replaced. (Refer to 23 - BODY/
SWING GATE/FLIP-UP GLASS LATCH - REMOV-
AL).
OPERATION
The flip-up glass ajar switch is actuated by the
flip-up glass latch mechanism. When the flip-up glass
is closed and properly latched, the flip-up glass ajar
switch is an open circuit. When the flip-up glass is
open or only partially latched, the flip-up glass ajar
switch is a closed circuit. The flip-up glass ajar
switch is hard wired between a body ground, the
Body Control Module (BCM), and the rear wiper
motor. The output of the switch is connected to the
BCM and rear wiper motor through a flip-up glass
ajar switch sense circuit. The BCM reads the flip-up
glass ajar switch status through an internal pull-up,
then uses this input to control many electronic func-
