Universal Transmitter: Description

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

Some DR models are equipped with a universal transmitter transceiver. The universal transmitter is integral to the Electronic Vehicle Information Center (EVIC) and the Compass Mini-Trip Computer (CMTC), which is located in the overhead console. The only visible component of the universal transmitter are the three transmitter push buttons centered between the modules push buttons located just rearward of the display screen in the overhead console. The three universal transmitter push buttons are identified with one, two or three light indicators so that they be easily identified.

Each of the three universal transmitter push buttons control an independent radio transmitter channel. Each of these three channels can be trained to transmit a different radio frequency signal for the remote operation of garage door openers, motorized gate openers, home or office lighting, security systems or just about any other device that can be equipped with a radio receiver in the 286 to 399 MegaHertz (MHz) frequency range for remote operation. The universal transmitter is capable of operating systems using either rolling code or non-rolling code technology.

The electronics module displays messages and a small house-shaped icon with one, two or three dots corresponding to the three transmitter buttons to indicate the status of the universal transmitter. The EVIC messages are:

Clearing Channels - Indicates that all of the transmitter codes stored in the universal transmitter have been successfully cleared.
Channel "X" Training - Indicates that the universal transmitter is in its transmitter learning mode.
Channel "X" Trained - Indicates that the universal transmitter has successfully acquired a new transmitter code.
Channel "X" Transmitting - Indicates that a trained universal transmitter button has been depressed and that the universal transmitter is transmitting.

The universal transmitter cannot be repaired, and is available for service only as a unit with the EVIC or CMTC modules. If any part of the universal transmitter is faulty or damaged, the complete EVIC or CMTC module must be replaced.
