Central Timer Module ( CTM ) Low Option: Description and Operation
CENTRAL TIMER MODULE
The Dakota (AN) and (AN84) utilize a Central Timer Module (CTM). This system is available in a Base or Highline configuration.
The CTM performs most of the typical functions a Body Control Module would perform.
Fig.1 Central Timer Module
Two versions of the Central Timer Module (CTM) are available on this vehicle. Whichever version of the CTM the vehicle is equipped with, it is
concealed behind the trim on the left cowl side inner panel below the instrument panel (Fig. 1). The base models are not equipped with the optional
power lock system, the Remote Keyless Entry (RKE) system, the Vehicle Theft Security System (VTSS), or the remote radio controls. The high-line
version of the CTM are used on vehicles that are equipped with one or more of those options.
The CTM utilizes circuitry, and information carried on the Programmable Communications Interface (PCI) data bus network, along with many hard
wired inputs to monitor many sensor and switch inputs throughout the vehicle. In response to those inputs, the programming of the CTM allow it to
supply the vehicle occupants with audible and visual information, and to control and integrate many electronic functions and features of the vehicle
through both hard wired outputs and the transmission of electronic message outputs to other electronic modules in the vehicle over the PCI data bus.
