Garage Door Opener Transmitter: Description and Operation
UNIVERSAL TRANSMITTER
On some LFI models a Universal Transmitter is standard factory-installed equipment. The universal transmitter transceiver is integral to the
Electronic Vehicle Information Center (EVIC), which is located in the overhead console. The only visible component of the universal transmitter
are the three transmitter push buttons centered between the four EVIC push buttons located just rearward of the EVIC 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
by sight.
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 288 to 410 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 EVIC 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 module. This unit includes the push button
switches and the plastic module. If any of these components is faulty or damaged, the complete EVIC module must be replaced.
The universal transmitter operates on a non-switched source of battery current so the unit will remain functional, regardless of the ignition switch
position. For more information on the features, programming procedures and operation of the universal transmitter, see the owner's manual in the
vehicle glove box.
