Grand Caravan V6-3.3L VIN R (2005)
Radio Frequency Detector
If both the Universal Transmitter and the Electronic Vehicle Information Center (EVIC) are inoperative. 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:
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.
