Garage Door Opener Transmitter: Description and Operation
Universal Transmitter - Description
DESCRIPTION
NOTE: The Electronic Vehicle Information Center (EVIC) module is sometimes referred to as the Electronic Overhead Module (EOM) for
the purposes of scan tool and diagnostic information naming. Please treat the EVIC and EOM as one and the same when diagnosing
the vehicle.
The HomeLink(R) transceiver is integral to the Electronic Vehicle Information Center (EVIC) module located in the overhead console. The only visible
component of the HomeLink(R) transceiver are the three transmitter push buttons (3). The buttons are marked with one, two or three dots, respectively,
for identification of each channel.
Each of the three HomeLink(R) transceiver push buttons controls an independent radio transceiver 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 HomeLink(R) transceiver is capable of operating systems using either rolling code or non-rolling code technology.
The HomeLink(R) transceiver cannot be repaired, and is available for service only as part of the EVIC module. This unit includes the push button
switches for both the transceiver (3) and EVIC (1, 2, 4 and 5) as well as the vacuum-fluorescent display (6) and the plastic module case. See:
Driver/Vehicle Information Display/Service and Repair/Removal and Replacement/Electronic Vehicle Information Center - Removal for replacement
