Audible Warning Device: Testing and Inspection

For Removal and Installation of Junction Block (JB).

For Removal and Installation of Body Control Module (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 DRBIII(R) scan tool to perform PCI data bus diagnostics on the BCM for battery, ignition and seat belt switch inputs.
3. Use DRBIII(R) scan tool to perform actuator diagnostics on BCM Chime.
4. Check for tone in any other function.

Junction Block Connector To The BCM:

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. 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 connectors, 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 DRBIII(R) 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 unbuckled, lamp is ON. If the status received by the instrument cluster does match the actual buckle seat belt switch status (buckled/unbuckled), then check the driver seat belt switch and wiring for proper connection.

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, Transmission Control Module (TCM) and Powertrain Control Module (PCM) must be operational.
1. Check all door jamb switches.
2. Use DRBIII(R) 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 DRBIII(R) 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 DRIVERS DOOR IS OPEN
1. Check left door jamb switch for good ground when drivers door is open.
2. Use DRBIII(R) 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 DRBIII(R) scan tool to perform PCI data bus diagnostics on BCM for headlamp or key-in-ignition 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.

EXTERIOR LAMPS LEFT ON
To test the headlamps left on function, turn ignition off, turn exterior lamps on with driver's door open. Chime should sound until headlamps are turned off or drivers door is closed.

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.

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.
