Driver/Vehicle Information Display: Description and Operation
Universal Transmitter
A Universal Transmitter transceiver is available on some vehicles. The universal transmitter transceiver is integral to the Electronic Vehicle Information
Center (EVIC) and the Compass Mini-Trip Computer (CMTC) modules, which are 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 can be easily identified.
Each of the three universal transmitter push buttons controls 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:
-
Cleared Channels - Indicates that all of the transmitter codes stored in the universal transmitter have been successfully cleared.
-
Training - Indicates that the universal transmitter is in its transmitter learning mode.
-
Trained - Indicates that the universal transmitter has successfully acquired a new transmitter code.
-
Transmit - 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 of these components is
faulty or damaged, the complete EVIC or CMTC module must be replaced.
