Grand Caravan V6-3.3L VIN R (2005)
Audible Warning Device: Testing and Inspection
NO TONE WHEN IGNITION SWITCH IS TURNED ON AND DRIVERS SEAT BELT IS NOT BUCKLED.
1. Using a DRB III (R) 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 12v
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 pin-out and location views for the various
wire harness connectors, splices and grounds.
3. Check drivers seat belt buckle switch input (from Occupant Restraint Controller (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 Programmable Communication Interface (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 manual.
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 (12v) on BCM connector (PX2) pin 34 with harness connected.
5. Check BCM sensors to verify headlamp switch position.
