Component Tests and General Diagnostics

HOMELINK(R) TRANSMITTER





RADIO FREQUENCY DETECTOR #9001

If both the HomeLink(R) Transmitter and the compass mini trip computer display are inoperative, refer to Driver/Vehicle Information Center or Garage Door Opener for further diagnosis. If the HomeLink(R) Transmitter is inoperative, but the compass mini trip computer display is operating normally, refer to instructions on training the HomeLink(R) Transmitter. Retrain the HomeLink(R) Transmitter with a known good hand held transmitter as instructed and test the HomeLink(R) Transmitter operation again. If the unit is still inoperative, test the HomeLink(R) transmitter with the Radio Frequency Detector special tool 9001 or equivalent 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 HomeLink(R) 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 HomeLink(R) transmitter assembly.

For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
