Central Timer Module

WARNING: This page is about a different car, the 2004 Dodge Dakota and 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

The high-line Central Timer Module (CTM) can also control some features of the audio system when the vehicle is equipped with the optional remote radio switches. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit.

The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The RAZ and RBQ radio receiver with a remote radio switch option is one of the features that the CTM controls. The CTM is programmed to send switch status messages over the Programmable Communications Interface (PCI) data bus to control the volume, seek, and pre-set station advance functions of the optional radio receiver. The CTM monitors the status of the remote radio switches located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch status messages to the radio receiver. The electronic circuitry within the radio receiver responds to the switch status messages it receives by adjusting the radio settings as requested.

(Refer to CENTRAL TIMER MODULE for more information on the high-line CTM.) (Refer to ELECTRICAL/AUDIO/REMOTE SWITCHES DESCRIPTION ) for more information on this component. In addition, radio receivers connected to the PCI data bus have several audio system functions that can be diagnosed using a DRB III(R) scan tool. Refer to BODY DIAGNOSTIC PROCEDURES (2003) or BODY DIAGNOSTIC PROCEDURES (2004) for more information on DRB III(R) testing of the audio systems.
