JEEP GRAND CHEROKEE 2002 WJ / 2.G Workshop Manual

²Hazard Warning Control- The hazard warn-
ing push button is pressed down to activate the haz-
ard warning system, and pressed down again to turn
the system off. The left multi-function switch pro-
vides a ground to the hazard warning sense input of
the combination flasher to control activation of the
hazard warning lamps.
²Headlamps- The Body Control Module (BCM)
monitors the left multi-function switch then, based
upon that multiplexed input, controls an output to
the headlamp low or high beam relays to illuminate
or extinguish the headlamps.
²Headlamp Beam Selection- The Body Control
Module (BCM) monitors the left multi-function
switch then, based upon that switched ground input,
controls an output to the headlamp low or high beam
relays to activate the selected headlamp beam.
²Headlamp Optical Horn- The Body Control
Module (BCM) monitors the left multi-function
switch then, based upon that switched ground input,
controls an output to the headlamp high beam relay
to activate the headlamp high beams.
²Park Lamps- The Body Control Module (BCM)
monitors the left multi-function switch then, based
upon that multiplexed input, controls an output to
the park lamp relay to illuminate or extinguish the
parking lamps.
²Rear Fog Lamps- The Body Control Module
(BCM) monitors the left multi-function switch then,
based upon that multiplexed input, controls an out-
put to the rear fog lamp relay to illuminate or extin-
guish the rear fog lamps.
²Turn Signal Control- The left multi-function
switch control stalk actuates the turn signal switch.
The Body Control Module (BCM) monitors the left
multi-function switch then, based upon that multi-
plexed input, provides a variable voltage output to
control the lighting of the turn signals.
Following are descriptions of the how the left
multi-function switch operates to control the many
interior lighting functions and features it provides:
²Panel Lamps Dimming- The Body Control
Module (BCM) monitors the left multi-function
switch then, based upon that multiplexed input, pro-
vides a variable voltage output through several panel
lamps driver circuits to control the lighting of many
incandescent panel lamps. The BCM also sends panel
lamps dimming messages over the Programmable
Communications Interface (PCI) data bus to other
modules to control Display lighting levels in those
modules.²Interior Lamps Defeat- The Body Control
Module (BCM) monitors the left multi-function
switch then, based upon that multiplexed input,
internally disables the function the BCM normally
provides to control the illumination of the interior
lamps.
²Interior Lamps On- The Body Control Module
(BCM) monitors the left multi-function switch then,
based upon that multiplexed input, provides a control
output to activate all of the interior lamp circuits.
²Parade Mode- The Body Control Module
(BCM) monitors the left multi-function switch then,
based upon that multiplexed input, provides a volt-
age output through several panel lamps driver cir-
cuits to control the lighting of many incandescent
panel lamps. The BCM also sends panel lamps dim-
ming messages over the Programmable Communica-
tions Interface (PCI) data bus to other modules on
the bus to control lighting levels in those modules.

TURN SIGNAL CANCEL CAM
DESCRIPTION
The turn signal cancel cam is concealed within the
multi-function switch housing below the steering
wheel and the clockspring mechanism. The turn sig-
nal cancel cam consists of a disc unit with two inte-
gral lobes. The upper lobe of the cam has an
alignment hole that is used to align it with another
hole in the back of the multi-function switch mount-
ing housing. The upper surface of the turn signal
cancel cam features three holes, two round and one
oblong. These holes engage and key the cancel cam to
three matching pins in the hub of the clockspring
mechanism. The hub of the clockspring and the turn
signal cancel cam rotate with the steering wheel. The
centered clockspring housing is then secured to the
multi-function switch mounting housing over the top
of the turn signal cancel cam.
The turn signal cancel cam is serviced as a assem-
bly with the multi-function switch housing. The turn
signal cancel cam cannot be repaired and, if faulty or
damaged, the multi-function switch mounting hous-
ing unit must be replaced. (Refer to 8 - ELECTRI-
CAL/LAMPS/LIGHTING - EXTERIOR/LEFT MULTI-
FUNCTION SWITCH - REMOVAL - MULTI-
FUNCTION SWITCH MOUNTING HOUSING).
OPERATION
The turn signal cancel cam has two lobes. When
the turn signals are activated by moving the left
multi-function switch control stalk to a detent posi-
tion, a turn signal cancel actuator is extended from
the inside surface of the multi-function switch hous-
ing toward the center of the steering column and the
turn signal cancel cam. When the steering wheel is
rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn sig-
nal cancel actuator. The cancel actuator latches
against the cancel cam rotation in the direction oppo-
site that which is signaled.

DOOR AJAR SWITCH
DESCRIPTION
DESCRIPTION - DOOR AJAR SWITCH
The door ajar switches are integral to the door
latch mechnicism. The front door ajar switches are
actuated by the front door latch mechanisms, and are
hard wired between a body ground and the Driver
Door Module (DDM) or the Passenger Door Module
(PDM). The rear door ajar switches are actuated by
the rear door latch mechanisms, and are hard wired
between a body ground and the Body Control Module
(BCM) through the rear door and body wire har-
nesses.
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/DOORS - REAR/LATCH - REMOVAL) for the
service procedures. For complete circuit diagrams,
refer to the appropriate wiring information.
