Universal Transmitter: Overview Jeep Compass I рестайлинг 2

Scheme 370

Some vehicles are equipped with a Universal Transmitter transceiver (4). The universal transmitter transceiver (4) is located in the headliner (5) just to the rear of the courtesy/reading lamps (1). The only visible component of the universal transmitter are the three transmitter push buttons. The three universal transmitter push buttons are identified with raised buttons and contain a transmit indicator that lights during operation and programming functions.

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 280 to 435 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 system will not transmit operating signals if the Vehicle Theft Security System is armed.

The universal transmitter cannot be repaired, and if inoperative or damaged, the complete module assembly must be replaced.

OPERATION

The HomeLink® transceiver 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 HomeLink® transceiver, see the owner's manual in the vehicle glove box.

If the universal transmitter is inoperative, retrain the universal transmitter with a known good transmitter. Be certain that the transmitter battery is okay. Refer to STANDARD PROCEDURE . Test the universal transmitter operation again. If the unit is still inoperative, test the universal transmitter with the Radio Frequency Detector special tool as described below

1. Turn the Radio Frequency (RF) Detector ON (3). An audible chirp will sound and the green power Light Emitting Diode (LED) unit (2) will light. If the green LED unit does not light, replace the battery (4).
2. Hold the RF detector within 2.5 cm (1 inch) of the TRAINED universal transmitter and press any one of the transmitter buttons.
3. The red signal detection LED units (1) will light and the tool will beep if a radio signal is detected. Repeat this test for all three transmitter buttons. If the tool does not detect a radio signal for any of the three buttons, replace the inoperative universal transmitter assembly. Refer to «REMOVAL»(ref-612742-S15413790692014043000000) .
