Turn Signal on Chime
No Tone When Ignition Switch Is Turned On And Driver's Seat Belt Is Not Buckled1. Using a scan tool (DRB) test:
a. BCM Sensor Test for battery voltage and ignition voltage.
b. BCM Switch Test for seat belt switch status with the belt buckle and unbuckled.
2. Using a voltmeter, check for voltage:
a. Pin 9 of the internal 23 way connector of the BCM for battery feed.
b. Pin 8 of the internal 23 way connector of the BCM for ignition feed.
c. If voltage OK, go to step Step 3
d. If NO voltage repair as necessary. Refer component locations and circuit information.
3. Check driver's seat belt buckle switch input for a ground when not buckled.
- If input not seen, look for open in wiring or switch. The switch is grounded when belt is not buckled.
4. Repair as necessary.
No Fasten Seat Belt Lamp When Ignition Switch Is Turned On
1. Verify that the cluster is operating and the seat belt lamp is not burned out.
- Use a multi-meter and test the two connectors at the rear of the cluster for:
- Battery feed Pin 5 of the Red connector.
- Ignition Feed, Pin 5 of the Blue connector with the ignition switch in the run position.
2. Repair as necessary.
Chime With Belt Buckled Or No Chime With Belt Unbuckled When Ignition Is Turned On
1. Check left seat belt buckle switch for closed circuit when the seat belt buckle is buckled.
a. Test the seat belt buckle connector, with the connector disconnected.
- Use a Ohmmeter, connect a lead to each of the terminals.
- No continuity when the seat belt buckle not buckled.
- Continuity when the seat belt buckle is buckled.
- If OK, go to Step b.
- If not OK, replace seat belt buckle switch.
b. Test Pin 78 of the BCM connector for continuity to ground when the seat belt buckle is connected.
- If OK, replace BCM for tone condition.
- If not OK, repair wire to seat belt buckle switch,
No Tone When Park Or Headlamps Are On And Driver's Door Is Open
1. Ensure that the ignition switch is OFF.
2. Check left door ajar switch for good ground when driver's door is open. Repair as necessary.
3. Inspect BCM connectors and wires for proper connection.
- If OK, replace BCM for tone condition.
DOME LAMP ON CHIME
The dome lamp on chime Will warn the driver that the dome lamps have been left on.
When the ignition is OFF:
- Driver's door OPEN (door ajar switch is closed to ground
- Dome lamps are ON (dome lamp switch is closed to ground),
The chime will sound continuously until Driver's door is closed, dome lamps tuned OFF or until the battery protection time out of 15 minutes has expired.
Chime rate: 168 to 192 chimes per minute.
ENGINE TEMPERATURE HIGH AND CRITICAL CHIME
The engine temperature high and critical chime will warn the driver that the engine is overheating. While monitoring the coolant temperature, the Powertrain Control Module (PCM) will send on the CCD bus as engine temperature every 1.376 seconds to the Body Control Module (BCM). The BCM calculates engine temperature and determines if a warning should occur. This feature is functional only with the Ignition Switch in the Run/Start position.
When the engine temperature reaches HIGH temperature of 121C (250F) the BCM will chime one tone and the engine temperature lamp comes ON. The BCM turns OFF the lamp when the engine temperature reaches 117°C (242°F). The BCM will chime a second warning when the engine temperature reaches CRITICAL temperature of 125°C (257°F).
EXTERIOR LAMPS ON CHIME
The exterior lamp on chime will warn the driver that the exterior lights have been left on.
With the ignition switch OFF:
- Driver's door is open (door ajar switch is closed to ground)
- Parking lamps or headlamps ON (parking lamp switch is closed to ground)
The chime will sound until lights are turned OFF, driver's door closed or until the battery protection time out of 3 minutes has expired.
Chime rate: 168 to 192 chimes per minute.
To test the exterior lamps left on function:
- Turn ignition off
- Remove ignition key
- Turn exterior lamps on with driver's door open. Chime should sound until lamps are turned off or driver's door is closed.
KEY-IN IGNITION CHIME
The key-in ignition chime will act as a warning to the driver that the ignition key has been left in the ignition switch.
With the ignition switch is in the OFF position ONLY:
- Driver's door is open/ajar (door ajar switch is closed to ground)
- Key is in the ignition switch (key-in ignition switch is closed to ground)
The chime will sound until one of the above conditions is removed.
Chime rate: 168 to 192 chimes per minute.
To test the key-in ignition function, insert key into the ignition and open Driver's door. Do not turn ignition ON. Chime should sound until key is removed from ignition or Driver's door is closed.
LOW OIL PRESSURE CHIME
The engine low oil pressure chime will warn the driver that the vehicle's engine oil pressure is low. The oil pressure switch, which will close to ground during a low oil pressure condition, will directly illuminate the check engine lamp located in the message center. The BCM will monitor the oil pressure switch and signal a low oil pressure condition with one warning chime when the following conditions are met:
1. Ignition switch is in the ON position
2. Engine running, indicated by RPM above 1,500±30 for 10 seconds.
3. Oil pressure switch closed to ground for one second minimum to two seconds maximum
SEAT BELT CHIME
The seat belt chime will sound for 4 to 8 seconds, when the ignition is turned on and the driver's seat belt is not buckled (seat belt switch is closed to ground). This is a reminder to the driver to buckle the seat belt. The seat belt lamp is controlled by the BCM via the CCD bus. The cluster will illuminate the seat belt warning lamp for 6 seconds. Buckling the Driver's seat belt before the time out has expired will cause the chime to stop immediately.
Chime rate: 38 to 62 chimes per minute.
To test the seat belt warning system, start with the ignition switch in the OFF position. Turn the ignition switch to the ON position with the driver's seat belt not buckled. The seat belt warning lamp should light and the chime should sound 4 to 8 seconds.
SEAT BELT LAMP
The seat belt lamp in the instrument cluster signals the driver's to fasten the seat belt. The seat belt lamp is illuminated for 6 seconds after the instrument cluster receives the message from the Body Control Module. The seat belt lamp is therefore illuminated for 6 seconds whenever the ignition switch is moved to run/start position. While ignition is off, the seat belt lamp will not be illuminated. This lamp will be illuminated for 6 seconds with every run/start cycle of the ignition switch.
Chime rate: 50±12 chimes per minute.
WARNING LAMP ANNOUNCEMENT CHIME
The warning lamp announcement chime will warn the driver to scan the instrument cluster to observe the gauges and lamp indicators. Whenever the check gauge, low fuel, low washer fluid level, door/check lid ajar, low tire pressure, low oil pressure, airbag warning, or service engine soon lamps are first illuminated, the chime will sound one tone. The door/deck lid ajar warning lamp announcement chime sounds only if the vehicle speed is above 2 m.p.h.
Two seconds after ignition switch is turned ON or until the seat belt warning chime ends, multiple warning announcement chimes will be consolidated into one warning announcement. This will occur 2 seconds after the seat belt warning chime ends.
