Durango 2WD V8-5.2L VIN Y (1999)
Audible Warning Device: Description and Operation
CHIME SYSTEM
The chime system is built into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the
instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 ± 12
chimes per minute for reminders and High; 180 ± 12 chimes per minute for serious conditions that require immediate attention. The high rate
chime sounds when the key is left in the ignition and the doors are open or the headlights are left ON. The low rate chime sounds for any of the
other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door
is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the
same time the warning light on the cluster is illuminated.

-
Ignition OFF, key in ignition, driver's door open
