Grand Caravan AWD V6-3.8L VIN L (2001)
Audible Warning Device: Testing and Inspection
Chime System Diagnosis
NO TONE WHEN IGNITION SWITCH IS TURNED ON AND DRIVER'S SEAT BELT IS NOT BUCKLED.
1. Using a DRB III scan tool, actuate chime (BCM actuates).
2. Using a voltmeter, check for voltage:
a. BCM has two battery feeds at pin 1 and pin 5 of the 6-way connector.
b. Pin 5 of the (BX2) 32 way connector of the BCM for ignition feed.
c. Check voltage (PX2) connector, pin 34 for 12 V.
d. If voltage OK, go to step Step 3
e. If NO voltage repair as necessary. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire
and connector repair procedures, further details on wire harness routing and retention, as well as pinout and location views for the various wire
harness connectors, splices and grounds.
3. Check driver's seat belt buckle switch input (form ORC) for a closed circuit when not buckled. If input not seen, look for open in wiring or switch.
The switch is grounded when belt is not buckled.
4. Verify PCI data bus communication between ORC and BCM.
NO FASTEN SEAT BELT LAMP WHEN IGNITION SWITCH IS TURNED ON.
1. Check for burned out lamp.
2. Using a voltmeter check for voltage at the cluster connector:
a. Pin 2 of the mechanical instrument cluster for battery feed.
b. Pin 11 of the mechanical instrument cluster for ignition voltage.
3. Repair as necessary.
FASTEN SEAT BELT LAMP OR TONE CONTINUES FOR MORE THAN 10 SECONDS AFTER SEAT BELTS ARE FASTENED AND
DRIVER'S DOOR IS CLOSED.
Refer to the proper Body Diagnostic Procedures.
NO TONE WHEN PARK OR HEADLAMPS ARE ON AND DRIVER'S DOOR IS OPEN.
Make sure ignition is in lock position with the key removed.
1. Check the BCM DTC's and BCM sensors to verify the door is open. Repair as necessary.
2. Actuate Chime (BCM actuates).
3. Inspect BCM connectors and wires for proper connection.
4. Measure with a voltmeter the voltage (12 V) on BCM connector (Px2) pin 34 with harness connected.
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) and
-
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 critical chime will warn the driver that the vehicle's engine is overheating. While monitoring the coolant temperature, the
Powertrain Control Module (PCM) will send on the PCI data bus as engine temperature every 1.376 seconds to the cluster. The MIC 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 122 °C (252 °F) the MIC requests a chime from the BCM and the engine temperature lamp comes ON. The MIC
turns OFF the lamp when the engine temperature reaches 117 °C (242 °F). The MIC will chime continuously (request from the BCM). The chime will
turn OFF after four minutes or when the temperature reaches 117 °C (242 °F), which ever occurs first.
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/key out of ignition:
-
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:
