8B - 4 CHIME/BUZZER - SERVICE INFORMATION
Hard wired circuitry connects many of the chime warning system components to each other through the electrical
system of the vehicle.
If the Instrument Cluster or the chime tone generator is damaged or faulty, the Instrument Cluster assembly must be
replaced.
DIAGNOSIS AND TESTING - CHIME WARNING SYSTEM
Refer to the appropriate wiring information. Conventional diagnostic methods may not prove conclusive in the diag-
nosis of the Instrument Cluster. The most reliable, efficient and accurate means to diagnose the Instrument Cluster
and the Controller Area Network (CAN) data bus network inputs for the chime warning system requires the use of
a DRB III scan tool and the appropriate diagnostic information.
WARNING: DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE
THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM
CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE
ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
CHIME WARNING SYSTEM DIAGNOSIS
CONDITION
NO SEAT BELT WARNING
CHIME WITH SEAT BELT
UNBUCKLED, BUT OTHER
CHIME FEATURES OK
SEAT BELT WARNING
CHIME SOUNDS WITH
SEAT BELT BUCKLED
POSSIBLE CAUSES
1. Seat belt switch ground
circuit open.
2. Seat belt switch sense
circuit open.
3. Faulty seat belt switch.
1. Seat belt switch sense
circuit shorted.
2. Faulty seat belt switch.
CORRECTION
1. Check for continuity between the ground circuit
of the wire harness connector for the seat belt
switch and a good ground. Repair the ground
circuit, if required.
2. Check for continuity between the seat belt
switch sense circuit of the wire harness connector
for the seat belt switch and the instrument cluster
wire harness connector. Repair the seat belt
switch sense circuit, if required.
3. Check for continuity between the ground circuit
and the seat belt switch sense circuit of the seat
belt switch pigtail wire connector. There should be
continuity with the seat belt unbuckled. Replace
the faulty seat belt, if required.
1. With the wire harness connector for the seat
belt switch and the instrument cluster wire
harness connector disconnected, there should be
no continuity between the seat belt switch sense
circuit and a good ground. Repair the seat belt
switch sense circuit, if required.
2. Check for continuity between the ground circuit
and the seat belt switch sense circuit of the seat
belt switch pigtail wire connector. There should be
no continuity with the seat belt buckled. Replace
the faulty seat belt, if required.
