GENERAL INFORMATION
INTRODUCTION
WARNING:
ON VEHICLES EQUIPPED WITH AN
AIRBAG, REFER TO THE AIRBAG PORTION OF
THIS SECTION FOR STEERING WHEEL OR SWITCH
REMOVAL AND INSTALLATION PROCEDURES.
The chime warning/reminder system includes sig-
nals for fasten seat belts, exterior lamps left on and
key left in ignition (Fig. 1).
When using the scan tool (DRB), refer to the

CHIME WARNING/REMINDER SYSTEM
8U - 1
DESCRIPTION AND OPERATION
EXTERIOR LAMPS LEFT ON
An audible chime tone indicates the exterior lamps
left on.
FASTEN SEAT BELTS
A warning lamp on the instrument panel, and an
audible chime tone are used as the fasten seat belt
warning/reminder.
KEY LEFT IN IGNITION
An audible chime tone that indicates the ignition
key was left in the ignition switch.
DIAGNOSIS AND TESTING
CHIME CONDITIONS
No tone when ignition switch is turned on and
drivers seat belt is unbuckled and fully
retracted.
(1) Check driver’s seat belt retractor switch for a
ground when belt is unbuckled.
(2) Use a scan tool (DRB) to perform PCI bus diag-
nostics on the Body Control Module (BCM) for bat-
tery, ignition and seat belt switch input.
(3) Use a scan tool to perform actuator diagnostics
on BCM chime.
(4) Check for battery feed at terminal J1-7 and
ignition feed at terminal J1-5 of the BCM connector.
(5) Check for tone in any other function.

GENERAL INFORMATION (Continued)
No fasten seat belt lamp when ignition switch
is turned on.
(1) Use scan tool to perform PCI bus diagnostics
on BCM for battery and ignition switch input
(2) Check for burned out bulb.
(3) Using the scan tool, do the actuator test on
cluster. Refer to proper Body Diagnostic Procedures
Manual.
(4) Check for battery feed at terminal J1-7 of the
BCM connector.
(5) Check for ignition feed at terminal J1-5 of the
BCM connector.
Fasten seat belt lamp or tone continue for
more than 10 seconds after seat belts are
fastened and ignition ON.
(1) Use scan tool to perform PCI bus diagnostics
on BCM for battery and ignition switch input.
(2) Inspect the BCM connectors and wires for
proper connection.
No tone when headlamps are on, ignition
switch is OFF and driver’s door is open.
(1) Using a scan tool (DRB), check drivers door
ajar switch for good ground when driver’s door is
open.
(2) Use scan tool to perform PCI bus diagnostics
on BCM for battery, ignition switch input, headlamp
switch and driver’s door input and Chime Output
Test.
(3) Inspect BCM connectors and wires for proper
connection.
(4) Check for battery feed at terminal J1-7 of BCM
connector.
(5) Check headlamp switch.
No tone when key is left in ignition. Ignition
switch is in the OFF position and driver’s door
is open.
(1) Using a scan tool (DRB), check drivers door
ajar switch for good ground when driver’s door is
open.
(2) Use scan tool to perform PCI bus diagnostics
on BCM for battery, ignition switch input, key-in-
switch and driver’s door input and Chime Output
Test.
(3) Inspect BCM connectors and wires for proper
connection.
(4) Check for battery feed at terminal J1-7 of BCM
connector.
(5) Check key-in switch.
Chimes continue when headlamps are turned
off and/or key is removed from ignition.
(1) Use scan tool to perform PCI bus diagnostics
on BCM for headlamp or key-in-ignition inputs.
(2) Check wiring for a grounded condition between
key-in switch and BCM.
(3) Inspect the BCM connectors and wires for
proper connection.
EXTERIOR LAMPS LEFT ON
To test the headlamps left on function, remove the
ignition key, turn exterior lamps on with driver’s
door open. Chime should sound until headlamps are
turned off or drivers door is closed.
FASTEN SEAT BELTS
To test the fasten seat belt function, start with the
ignition switch in the OFF position. Turn the ignition
switch to the ON position with the driver’s seat belt
unbuckled. The seat belt warning lamp should light
for 4 to 8 seconds and the tone should sound 4 to 8
seconds.
KEY LEFT IN IGNITION
To test the key left in ignition function, the ignition
switch must be in the OFF position with key in the
ignition switch. The driver’s door must be open. The
chime should sound until key is removed from igni-
tion switch or drivers door is closed.
REMOVAL AND INSTALLATION
BODY CONTROL MODULE REMOVAL
Refer to Group 8E, Instrument Panel and Systems
for Removal and Installation procedures.
HEADLAMP SWITCH
Refer to Group 8E, Instrument Panel and Systems
for Headlamp Removal and Installation procedures.
SEAT BELT BUCKLE
Refer to Group 23, Body for Seat Belt Buckle
Removal and Installation procedures.
