UNIVERSAL TRANSMITTER
If the Universal Transmitter is inoperative, but the Electronic Vehicle Information Center (EVIC) is operating normally. 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 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.
If both the Transmitter and the EVIC module are inoperative. Refer to the appropriate wiring information for complete circuit schematic or connector
pin-out information.
