Using Special Tool 9001, first test to ensure that the transmitter is functioning. Typical testing distance is 1 in. (2.5 cm) for Asian transmitters, and 12 in. (30.5 cm) for all others. To test, position the transmitter as shown. Press any transmitter button, then test each button individually. The tool will beep if a radio signal strength that lights five or more LEDs is detected. Repeat this test three times. If transmitter fails any of the tests, refer to POWER LOCKS - ELECTRICAL DIAGNOSTICS .
