Description
DESCRIPTION
NOTE: The Compass Mini-Trip Computer (CMTC) and Electronic Vehicle Information Center (EVIC) modules are sometimes referred to as
Electronic Overhead Modules (EOM) for the purposes of scan tool and diagnostic information naming. Please treat the CMTC, EVIC and
EOM as one and the same when diagnosing the vehicle.
NOTE: Overhead console with Compass Mini-Trip Computer (CMTC) shown. Overhead console with Electronic Vehicle Information Center
(EVIC) is similar.
The HomeLink(R) transceiver is integral to the CMTC or EVIC modules. The only visible component of the HomeLink(R) transceiver are the three 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 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 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 CMTC or EVIC modules. This unit includes the push
button switches for both the HomeLink(R) transceiver and CMTC or EVIC, The Vacuum-Fluorescent Display (VFD) and the plastic module case.
