Universal Transmitter: Description
Vehicles equipped with the optional universal transmitter (also known as the HomeLink® transmitter or Universal Garage Door Opener/UGDO) have a universal transmitter switch pod integral to the overhead console located in the headliner just behind the windshield opening header. The switch buttons are centered between the two map/reading lamps, forward of the sunglasses storage bin and, if equipped, the power sunroof switch. This switch has three momentary push buttons clearly marked by the Roman numerals I, II and III for identification of each of the three transmitter channels. The switch push buttons have instrument panel dimmer controlled LED units that provide back lighting for visibility at night.
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 (RF) signal for the remote operation of garage door openers, motorized gate openers, home or office lighting, security systems or most any other device equipped with a RF receiver operating in the 286 to 440 and 902 to 927 MegaHertz (MHz) frequency ranges. The transmitter is capable of operating systems using either rolling code or non-rolling code security technology.
The universal transmitter switch pod cannot be repaired and is only serviced as a unit with the overhead console. If the transmitter or any of the switches are ineffective or damaged, the entire overhead console unit must be replaced.
