8B - 2 CHIME/BUZZER
CHIME/BUZZER (Continued)
RUN position, the chime will sound six times (about
2 seconds). The chime will be a "fast" chime (same as
door ajar). The transmission has reverse gear adja-
cent to first gear. There is a 6-7 second delay to
accommodate mandatory bulb check and chimes (air-
bag, etc). The cluster monitors the reverse circuit and
chime as required.
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - BRAKE/PARK
BRAKE INDICATOR
The brake/park brake indicator illuminates when
the parking brake is applied with the ignition switch
turned to the ON position. The same lamp will also
illuminate if one of the two (hydraulic or ABS) ser-
vice brake systems fail when the brake pedal is
applied.
To test the system:
• As the ignition switch is turned to the START
position the lamp should light.
• Turn ignition switch to the ON position and
apply the parking brake. The lamp should light.
If lamp fails to light inspect for:
• A burned out lamp
• Loose, corroded or damaged socket
• A damaged circuit board
• A broken or disconnected wire at the switch
• Defective switch
To test the service brake warning system, refer to
Brakes, Diagnosis and Testing, Base Brake System
Diagnosis Charts, Red Brake Warning Lamp.
DIAGNOSIS AND TESTING - CHIME
CONDITIONS
NO TONE WHEN IGNITION SWITCH IS TURNED ON
AND DRIVERS SEAT BELT IS UNBUCKLED
(1) Using an ohmmeter, with the seat belt fully
retracted, check for continuity to ground at Pin 20 of
the 26-way cluster harness connector. If OK, go to
step 2. If not OK, repair as necessary.
(2) Using voltmeter, check for battery feed at Pin 4
of the 26-way cluster harness connector. Check for
ignition feed at Pin 14 of the 26-way cluster harness
connector. If not OK, repair as necessary.
NO FASTEN SEAT BELT LAMP WHEN IGNITION
SWITCH IS ON
(1) Check for battery feed at cluster harness con-
nector Pin 4.
(2) Check for ignition feed at cluster harness con-
nector Pin 14. Repair as necessary.
NO TONE WHEN HEADLAMPS ARE ON AND
DRIVERS DOOR IS OPEN
(1) Remove the key from the ignition.
(2) Check left door jamb switch for good ground
when drivers door is open.
(3) Check for ground at Pin 1 of the 26-way cluster
harness connector.
(4) Check for battery feed at cluster harness con-
nector Pin 4 of the 26-way cluster harness connector.
(5) Check for NO voltage at Pin 14. Ignition volt-
age must not be present for the chime to work.
(6) Check headlamp switch.
NO TONE WHEN KEY IS LEFT IN IGNITION AND
DRIVERS DOOR IS OPEN
(1) Check for continuity to ground at Pin 1 of the
26-way cluster harness connector. If OK, go to Step 4.
If not OK, repair as necessary.
(2) Check pin 19 of the 26-way connector to ground
while pulling key out/in from ignition switch. If not
chime, check ignition switch for problems.
(3) Using voltmeter, check for battery feed at Pin
21 of the 26-way cluster harness connector. Check for
NO ignition feed at Pin 14 of the 26-way cluster har-
ness connector. If OK, go to Step 4. If not OK, repair
as necessary.
(4) Open driver's door and ensure the ignition key
is in the OFF, LOCK, or ACC position. Check for con-
tinuity to ground at Pin 9 of the 26-way cluster har-
ness connector. If ground OK, replace cluster printed
circuit board. If no ground, check key-in switch or
door switch wiring and repair as necessary.
DIAGNOSIS AND TESTING - FASTEN SEAT
BELTS
To test the fasten seat belts function, turn the igni-
tion switch to the ON position with the driver's seat
belt unbuckled and fully retracted. The seat belt
warning lamp should light for four to eight seconds
and the tone should sound three to five times.
If the lamp does not light, check the connection at
the seat belt retractor. Replace as necessary.
DIAGNOSIS AND TESTING - KEY IN IGNITION
To test the key left in ignition function, insert key
into the ignition and open the driver's door. Chime
should sound until key is removed from ignition or
driver's door is closed.
If these conditions are met and there is still a
problem with the system, refer to Chime System
Conditions in this section for further diagnosis and
testing.
