Garage Door Opener Transmitter: Testing and Inspection
UNIVERSAL TRANSMITTER
If both the Universal Transmitter and the Electronic Vehicle Information Center (EVIC) are inoperative, refer to Driver/Vehicle Information Display
testing. If the Universal Transmitter is inoperative, but the EVIC is operating normally, retrain the Transmitter with a known good transmitter. If the unit
is still inoperative, test the universal transmitter with the Radio Frequency Detector special tool as described below(Figure 1):
1. Turn the Radio Frequency (RF) Detector ON. A "chirp" will sound and the green power LED will light. If the green LED does not light, replace
the battery.
2. Hold the RF detector within one inch of the TRAINED universal transmitter and press any of the transmitters buttons.
3. The red signal detection LEDs will light and the tool will beep if a radio signal is detected. Repeat this test three times.
