Universal Transmitter
WARNING: This page is about a different car, the 2007 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
If the Universal Transmitter is inoperative, but the Electronic Vehicle Information Center (EVIC) is operating normally, see STANDARD PROCEDURE 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:
- 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.
- Hold the RF detector within one inch of the TRAINED universal transmitter and press any of the transmitters buttons.
- 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 REMOVAL .
If both the Transmitter and the Electronic Overhead Module (EOM) are inoperative, see DIAGNOSIS AND TESTING for further diagnosis. Refer to the appropriate wiring information for complete circuit schematic or connector pin-out information.
