Garage Door Opener Transmitter: Description and Operation
UNIVERSAL TRANSMITTER
On some LH models a Universal Garage Door Opener (UGDO) transceiver is standard factory-in-stalled equipment. The UGDO transceiver is
integral to the Electronic Vehicle Information Center (EVIC), which is located in the overhead console. The only visible component of the UGDO
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 UGDO transmitter push buttons are identified with one, two or three light indicators so that they be easily identified
by sight or by feel.
Each of the three UGDO 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 Mega Hertz (MHz) frequency range
for remote operation. The UGDO 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 UGDO. The EVIC messages are:
-
Cleared Channels - Indicates that all of the transmitter codes stored in the UGDO have been successfully cleared.
-
Training - Indicates that the UGDO is in its transmitter learning mode.
-
Trained - Indicates that the UGDO has successfully acquired a new transmitter code.
-
Transmit - Indicates that a trained UGDO transmitter button has been depressed and that the UGDO is transmitting.
The UGDO 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 and display lens. If any of these components is faulty or damaged, the complete EVIC module must be replaced.
The UGDO 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 UGDO, see the owner's manual in the vehicle glove box.
