Grand Caravan FWD V6-3.3L VIN 3 Flex Fuel (2002)
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 Left In Ignition Chime Test
The key-in ignition chime will act as a warning to the driver that the ignition key has been left in the ignition switch. This chime will operate for all
ignition positions except ON and START.
With the ignition switch in the OFF position ONLY
-
Driver's door is open/ajar (door ajar switch is closed to ground)
-
Key is in the ignition switch (ignition is in the LOCK position)
The chime will sound until one of the above conditions is removed or until battery protection time out (15 mm.) has expired. Chime rate: 168 to 192
chimes per minute.
To test the key-in ignition function, insert key into the ignition and open drivers door. Do not turn ignition ON. Chime should sound until key is removed
from ignition or drivers door is closed.
For diagnosis and testing of the Key-In chime for other ignition positions, use the same testing procedure as above but with the key in the accessory or
unlock position.
Low Oil Pressure Chime Test
The low oil pressure chime will warn the driver that the engine oil pressure is low. The oil pressure switch will close to ground during a low oil pressure
condition. The oil pressure lamp will illuminate in the message center. The PCM will monitor the oil pressure switch and signal a low oil pressure
condition. A continuous four minute warning chime will sound and the oil pressure lamp will come ON when the following conditions are met:
-
Ignition on and engine not cranking
-
Engine running at 420 to 480 rpm for 10 seconds
-
Oil pressure switch closed to ground for (1 second minimum, 2 seconds maximum)
Chime rate: 168 to 192 chimes per minute.
Seat Belt Chime Test
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 ORC. The cluster will also bulb check 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 but the lamp will remain ON until 6 seconds have expired.
To test the seat belt warning system, the ignition switch must be in the OFF position for 1 minute before starting the test. 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.
Tire Pressure Monitor Test
The Tire Pressure Warning chime, as well as the information being displayed in the EVIC, will act as a warning to the driver that a tire has either Low or
High pressure, or if there is a need to service the Tire Pressure Monitor System. With the ignition switch in the ON position and the "Low Pressure/ High
Pressure" or "Service the TPM System" displayed on the EVIC display, a single chime will sound.
Turn Signal ON Chime
The turn signal on chime will warn the driver that the turn signals have been left ON. When the body control module receives a turn signal input for 1.0
mile, vehicle speed is greater than 24 km/h (15 mph), the chime will sound continuously until the turn signal is turned OFF. If vehicle speed drops
below 24 km/h (15 mph) prior to the warning being activated, the accumulated distance traveled will be reset. The turn signal chime is not activated
when the emergency flashers are turned ON. Chime rate: 50 ± 12 chimes per minute.
For the turn signal warning system to operate:
-
Must have input from either the right or left turn signal lamps. Creates a voltage change between 0 and battery voltage.
-
The vehicle speed sensor sends a message to the Powertrain Control Module that vehicle has exceeded 24 km/h (15 mph) for 1.0 mile).
-
When the above two conditions are met, the chime will sound. The chime will stop when no further voltage change is detected.
-
If hazard warning signals are pulsing, no chime will sound.
-
If speed drops below 24 km/h (15 mph) before the warning is issued, the warning will not be issued and the distance counter will be reset.
-
If turn signal lamps are not working properly, the chime will not sound.
-
When using the scan tool, refer to the proper Body Diagnostic Manual for the procedure.
Warning Lamp Announcement Chime Test
The warning lamp announcement chime will warn the driver to scan the instrument cluster to observe which warning lamp is illuminated. Whenever the
volts, low fuel, airbag, door ajar or gate ajar lamps are first illuminated, the chime will sound one tone. The door/liftgate ajar warning lamp
announcement chime sounds only if the vehicle speed is above 4 m.p.h.
