DIAGNOSIS AND TESTING

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 DRB lll

t scan tool to perform PCI bus

diagnostics on the Body Control Module (BCM) for
battery, ignition and seat belt switch input.

(3) Use a DRB lll

t 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.

No fasten seat belt lamp when ignition switch is
turned on.

(1) Use DRB lll

t scan tool to perform PCI bus

diagnostics on BCM for battery and ignition switch
input

(2) Check for burned out bulb.
(3) Using the DRB lll

t scan tool, do the actuator

test on cluster. Refer to proper Body Diagnostic Pro-
cedures 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 DRB lll

t 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 DRB lll

t scan tool, check drivers door

ajar switch for good ground when driver’s door is
open.

(2) Use DRB lll

t 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 DRB lll

t scan tool, check drivers door

ajar switch for good ground when driver’s door is
open.

(2) Use DRB lll

t scan tool to perform PCI bus

diagnostics on BCM for battery, ignition switch input,
key-in-switch and driver’s door input and Chime Out-
put 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 DRB lll

t 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.

NOTE: Refer to Electrical, Electronic Control Mod-
ules, Body Control Module, Removal and Installa-
tion for service of the BCM.

DIAGNOSIS AND TESTING - EXTERIOR LAMPS
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.

Refer to Electrical, Lamps/Lighting - Exterior,

Headlamp Switch, Removal and Installation for ser-
vice procedures.

DIAGNOSIS AND TESTING - 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 will stay lit
until the belt is moved sufficiently to buckle the belt.
If the belt is not buckled, the light will not go out.

Refer to Electrical, Restraints, Seat Belt Buckle,

Removal and Installation for service procedures.

DIAGNOSIS AND TESTING - KEY IN IGNITION

To test the key 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 the
ignition switch or the drivers door is closed.

The Key-in Ignition switch is built into the ignition

switch assembly. Should the Key-in switch require
service,

the

ignition

switch

assembly
