Dakota R/T 2WD V8-5.9L VIN Z (1998)
Power Door Lock Control Module: Description and Operation
Central Timer Module
The Dakota (AN) and Durango (DN) utilizes a Central Timer Module (CTM). This system is available in a Base or Highline configuration. The Base
CAM, (Dakota) and the Interior Electronic Module (IEM) in Durango does not communicate on the CCD bus. 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)
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.
The CTM is fully addressable with the DRB III and it is the recommended method for diagnosis. The CTM reports 6 Diagnostic Trouble Codes. All
of the inputs to the CTM can be read with the DRB and the output can be actuated. If the inputs are OK and the outputs can be cycled with the DRB,
the problem is usually the Central Timer Module.
