GENERAL INFORMATION
This group covers the buzzer warning system,
which is standard equipment on XJ (Cherokee)/YJ
(Wrangler) models. The system provides an audible
warning to the driver when it monitors the following
conditions:
²key is in ignition switch with the driver's door
open
²head or park lamps are on with driver's door open
(XJ only)
²driver's seat belt is not buckled with ignition
switch in ON position.
Following are general descriptions of the major
components in the buzzer warning system. Refer to
Group 8W - Wiring Diagrams for complete circuit de-
scriptions and diagrams.
BUZZER MODULE
The buzzer module is located in the fuseblock mod-
ule under the left end of the instrument panel. It re-
ceives battery voltage at all times from (fuse 15 - XJ,
fuse 3 - YJ) the fuseblock module. It also receives a
second battery feed (fuse 17 - XJ, fuse 9 - YJ) when
the ignition switch is in the ON or START position.
Other inputs to the module include the driver's door
jamb switch, the driver's seat belt switch, the ignition
key-in switch, and the headlamp switch (XJ only). The
only output of the module is a timed 4 to 8 second feed
to the seat belt reminder lamp in the message center of
the instrument cluster. The timer function begins after
the ignition switch is turned to the ON position.
The buzzer module can not be repaired. If faulty, it
must be replaced.
DRIVER'S DOOR JAMB SWITCH
The driver's door jamb switch is mounted to the
driver's door hinge pillar. The switch closes a path to
ground for the buzzer module through the key-in
switch or headlamp switch (XJ only) when the driv-
er's door is opened, and opens when the driver's door
is closed. This switch can not be repaired. If faulty, it
must be replaced.
IGNITION KEY-IN SWITCH
XJ MODELS
The key-in switch is integral to the ignition switch,
which is mounted on the right side of the steering col-
umn. It closes a path to ground for the buzzer module
when the ignition key is inserted in the ignition lock cyl-
inder and the driver's door jamb switch is closed (door
open). The switch opens when the key is removed from
the ignition lock cylinder. This switch can not be re-
paired. If faulty, the entire ignition switch must be re-
placed. Refer to Group 8D - Ignition Systems for service
procedures.
YJ MODELS
The key-in switch is mounted within the steering col-
umn in the lock cylinder housing. It closes a path to
ground for the buzzer module when the ignition key is
inserted in the ignition lock cylinder and the driver's
door jamb switch is closed (door open). The switch opens
when the key is removed from the ignition lock cylinder.
This switch is available for service replacement. Refer
to Group 19 - Steering for service procedures.
HEADLAMP SWITCH (XJ ONLY)
The headlamp switch is located in the instrument
panel. It closes a path to ground for the buzzer module
when the park or headlamps are on and the driver's
door jamb switch is closed (door open). The switch opens
the ground path when the park and headlamps are
turned off. The headlamp switch can not be repaired. If
faulty, it must be replaced. Refer to Group 8E - Instru-
ment Panel and Gauges for service procedures.
DRIVER'S SEAT BELT SWITCH
The driver's seat belt switch is integral to the driv-
er's seat belt buckle-half assembly. The switch is nor-
mally closed, providing a ground path to the buzzer
module. When the tip-half of the seat belt is inserted
into the seat belt buckle, the switch opens the buzzer
module ground path. The seat belt switch can not be
repaired. If faulty, the entire driver's seat belt buck-
le-half must be replaced. Refer to Group 23 - Body
Components for service procedures.

DIAGNOSIS
BUZZER MODULE
(1) Check fuses (15 and 17 - XJ, 3 and 9 - YJ) in
the fuseblock module. If fuses are OK, go to next
step. If not OK, replace fuses as required.
(2) Check for battery voltage at fuse (15 - XJ, 3 -
YJ) in fuseblock module. If OK, go to next step. If not
OK, repair feed circuit from power distribution center
as required.
(3) Turn ignition switch to ON position. Check for
battery voltage at fuse (17 - XJ, 9 - YJ) in the fuse-
block module. If OK, go to next step. If not OK, re-
pair feed from ignition switch as required.
(4) Turn ignition switch to OFF position. Replace
buzzer module with a known good unit and test op-
eration. If not OK, remove buzzer module and go to
next step.
(5) Check for battery voltage at cavity for buzzer
terminal 7 in buzzer module connector (Fig. 1). If
OK, go to next step. If not OK, repair circuit to fuse
(15 - XJ, 3 - YJ).
(6) Turn ignition switch to ON position. Check for
battery voltage at cavity for buzzer terminal 1 in
buzzer module connector. If OK, go to next step. If
not OK, repair circuit to fuse (17 - XJ, 9 - YJ) in fuse-
block module.
(7) Turn ignition switch to OFF position. Check for
continuity between cavity for buzzer terminal 3 and
a good ground. There should be continuity. If OK, go
to diagnosis for switch that is related to buzzer mal-
function. If not OK, repair circuit to ground as re-
quired.
DRIVER'S DOOR JAMB SWITCH
