Central Timer Module

Central Timer Module (CTM) communicates with other modules over Programmable Communication Interface (PCI) bus network. PCI bus is a single wire multiplexed network capable of supporting binary encoded messages shared between multiple modules. Modules are wired in parallel. Messages are addressed to only be recognized by the module(s) in which the message was intended. This reduces the complexity of vehicle wiring and size of wiring harness. CTM fault messages are accessed through 16-pin Data Link Connector (DLC) using Chrysler's Diagnostic Readout Box (DRBIII(R)) scan tool, or generic scan tool. CTM controls and supports the following features (if equipped).
