Garage Door Opener Transmitter: Component Tests and General Diagnostics
UNIVERSAL TRANSMITTER
If the Universal Transmitter is inoperative, but the Electronic Vehicle Information Center (EVIC) is operating normally,See: Programming and
Relearning for instructions on training the Transmitter. Retrain the Transmitter with a known good transmitter as instructed and test the Transmitter
operation again.
If the unit is still inoperative, test the universal transmitter with Radio Frequency Detector special tool as described below:
1. Turn the Radio Frequency (RF) Detector ON. A "chirp" will sound and the green power Light Emitting Diode (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 for each button. If any button is
inoperative, replace the universal transmitter assembly, See: Service and Repair/Universal Transmitter - Removal.
If both the Transmitter and the EVIC module are inoperative,See: Driver/Vehicle Information Display/Testing and Inspection for further diagnosis.
Refer to the appropriate wiring information for complete circuit schematic or connector pin-out information.
