accompanied with a continuous chime for approxi-
mately ninety-six seconds or until the driver seat belt
is buckled. When the enhanced seat belt feature is
not initiated or if the feature is disabled, the seat
belt indicator will be turned ON continuously until
the driver seat belt is buckled.

In the same ignition cycle, if the seat belt is again

unbuckled for more than ten seconds with the vehicle
speed greater than five mph (8 km/h), the enhanced
seat belt reminder feature will again be initiated.

The enhanced seat belt reminder feature is cus-

tomer programmable and can be enabled/disabled
with the use of a DRBIII

t scan tool, or by the cus-

tomer completing a sequence of steps.

CUSTOMER PROGRAMMING OF ENHANCED SEAT BELT
REMINDER FEATURE

(1) With the ignition not in RUN or START, buckle

the driver seat belt.

(2) Turn the ignition switch to the RUN or START

position and wait for the seat belt reminder check to
be completed.

(3) Unbuckle and then re-buckle the driver seat

belt causing the indicator to go ON and OFF three or
more times ending with the seat belt buckled.

(4) Return the ignition switch back to a non-RUN

or no-START position (the feature will toggle from
the current status) and a confirmation chime will
sound indicating to the customer the proper sequence
to enable/disable the feature was performed.

EXTERIOR LAMPS LEFT ON

An audible chime tone that indicates the exterior

lamps were left on.

FASTEN SEAT BELTS

At power up, a seat belt lamp bulb check will be

conducted by the instrument cluster. If the driver
side seat belt buckle is unbuckled during the bulb
check, an accompanying chime will sound within the
duration of the bulb check.

KEY LEFT IN IGNITION

An audible chime tone that indicates the key was

left in ignition.

SINGLE WARNING CHIME

After bulb check at power-up, if any of the follow-

ing indicators are still activated, the cluster will
request a single chime from the BCM. ABS, Air Bag,
Check Engine, Charging System, Engine Tempera-
ture, Low Fuel (after 10 seconds for accurate fuel
information), and BRAKE (if speed is greater than 2
mph).

DIAGNOSIS AND TESTING

DIAGNOSIS AND TESTING - CHIME
CONDITIONS

For Removal and Installation of Junction Block

(JB) (Refer to 8 - ELECTRICAL/POWER DISTRIBU-
TION/JUNCTION BLOCK - REMOVAL).

For Removal and Installation of Body Control Mod-

ule (BCM), refer to Electrical, Electronic Control
Modules,

Body

Control

Modules,

Removal,

and

Installation.

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 retracted.

(2) Use DRB III

t scan tool to perform PCI data

bus diagnostics on the BCM for battery, ignition and
seat belt switch inputs.

(3) Use DRB III

t scan tool to perform actuator

diagnostics on BCM Chime.

(4) Check for tone in any other function.
(5) Remove BCM from Junction Block. Check for

battery voltage at terminal JB-12 and ignition feed
at terminal JB-6 of BCM (Fig. 1). Refer to the appro-
priate 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 connec-
tors, splices and grounds.

(6) If voltage not OK, repair as necessary.

NO FASTEN SEAT BELT LAMP WHEN IGNITION
SWITCH IS TURNED ON

(1) At power-up, the cluster will turn ON the seat

belt warning indicator for 6 ± 1 seconds as required
regardless of the driver side seat belt buckle status.
If the warning indicator does not turn ON, verify if
the socketed red LED is seated properly and good
contact with the PC-board is present. If not seated
properly, then seat the LED properly by twisting the
socket counterclockwise. If seated properly, replace
the LED.

SEAT BELT LAMP ON FOR MORE THAN 7
SECONDS AFTER DRIVER SEAT BELT BUCKLE
SWITCH IS FASTENED AND IGNITION ON

(1) Use a DRB III

t scan tool to verify status of the

driver seat belt buckle switch as received by the
instrument cluster. Compare to the actual seat belt
buckle status: If buckled, lamp is OFF or if unbuck-
led, lamp is ON. If the status received by the instru-
ment cluster does match the actual buckle seat belt
switch status (buckled/unbuckled), then check the
driver seat belt switch and wiring for proper connec-
tion.

NO TONE OR DOOR INDICATED IN PLACE OF
ODOMETER WHEN A DOOR IS AJAR AND VEHICLE
BEGINS MOVING

The vehicle must be moving for the chime to occur.

However the door indicator will come ON regardless
of the vehicle movement. The PCI data bus, Trans-
mission Control Module (TCM) and Powertrain Con-
trol Module (PCM) must be operational.

(1) Check all door jamb switches.
(2) Use DRB III

t scan tool to perform PCI data

bus diagnostics on BCM for battery and ignition
switch input

(3) Inspect BCM connectors and wires for proper

connection.

(4) Remove BCM from Junction Block. Check for

battery voltage at terminal JB-12 and ignition feed
at terminal JB-6 of BCM. Refer to the appropriate
wiring information.

(5) If voltage not OK, repair as necessary.

NO TONE WHEN HEADLAMPS ARE ON, IGNITION
SWITCH IS OFF AND DRIVER’S DOOR IS OPEN.

(1) Check left door jamb switch for good ground

when driver’s door is open.

(2) Use DRB III

t scan tool to perform PCI data

bus diagnostics on BCM for battery, ignition switch
input, headlamp and driver’s door input and Chime
Output Test.

(3) Check headlamp switch.
(4) Inspect BCM connectors and wires for proper

connection.

(5) Remove BCM from Junction Block. Check for

battery voltage at terminal JB-12 and ignition feed
at terminal JB-6 of BCM. Refer to the appropriate
wiring information.

(6) If voltage not OK, repair as necessary.

NO TONE WHEN IGNITION KEY IS LEFT IN
IGNITION SWITCH AND IT IS IN THE OFF
POSITION WITH DRIVER’S DOOR IS OPEN

(1) Check left door jamb switch for good ground

when drivers door is open.

(2) Use DRB III

t scan tool to perform PCI data

bus diagnostics on BCM for battery, ignition switch
input, key-in-switch and driver’s door input and
Chime Output Test.

(3) Check key-in switch.
(4) Inspect BCM connectors and wires for proper

connection.

(5) Remove BCM from Junction Block. Check for

battery voltage at terminal JB-12 and ignition feed
at terminal JB-6 of BCM. Refer to the appropriate
wiring information.

(6) If voltage not OK, repair as necessary.

CHIMES CONTINUE WHEN HEADLAMPS ARE
TURNED OFF AND/OR KEY IS REMOVED FROM
IGNITION

(1) Use DRB III

t scan tool to perform PCI data

bus diagnostics on BCM for headlamp or key-in-igni-
tion inputs.

(2) Check wiring for a grounded condition between

key-in switch and BCM. Check headlamp switch to
BCM wiring for short to battery.

(3) Inspect BCM connectors and wires for proper

connection.

DIAGNOSIS AND TESTING - EXTERIOR LAMPS
LEFT ON

To test the headlamps left on function, turn igni-

tion off, turn exterior lamps on with driver’s door
open. Chime should sound until headlamps are
turned off or drivers door is closed.

DIAGNOSIS AND TESTING - KEY LEFT IN
IGNITION SWITCH

To test the key left in ignition function:
• The ignition switch must be in the OFF position

with key in ignition.

• Driver’s door open.

• Chime should sound until key is removed from

ignition or drivers door is closed.

DIAGNOSIS AND TESTING - FASTEN SEAT
BELTS

To test, the ignition switch must be in the OFF

position before testing the fasten seat belts. Turn the
ignition switch to the ON position with the driver’s
seat belt unbuckled. The seat belt warning lamp
should light for 5 to 7 seconds and the chime should
sound 5 to 7 seconds.
