AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE
MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT.
CENTRAL TIMER MODULE
The Durango utilizes a Central Timer Module (CTM). This system is available in a Base or Highline configuration. The Base CTM does not
communicate on the CCD bus and will not be addressed. The CTM performs most of the typical functions a Body Control Module would perform.
The Highline CTM provides the following features:
-
Remote Keyless Entry (RKE)
-
Chime
-
Courtesy Lamp controls/Illuminated Entry
-
Power Door Locks
-
Speed Sensitive Intermittent Wipers
-
Enhanced Accident Response
-
Vehicle Theft Security System (VTSS)
The module is located on the right side of the glove box behind a metal bracket. It contains a white 18-way and a green 14-way connector.
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.
The chime will sound for the following conditions:
-
Ignition OFF, key in ignition, driver's door open
-
Ignition OFF, headlamps ON, driver's door open
-
Seat belt warning
-
Check engine lamp illuminated (after prove-out)
